A prospective study of the effect of functional endoscopic sinus surgery on the recovery of olfactory function in patients with chronic rhinosinusitis with nasal polyposis / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the efficacy of functional endoscopic sinus surgery（FESS） in the treatment of olfactory dysfunction in patients with chronic rhinosinusitis with nasal polyps （CRSwNP） , at the same time, it provides an evidence for the prognosis evaluation of olfaction and the clinical application of oERPs to evaluate the plasticity of olfaction cortex. Methods:From October 2021 to October 2022, 45 patients with CRSwNP who underwent FESS nine-step standardized treatment in our department were recruited as the research subjects, divided into 22 patients with eosinophilic CRSwNP（ECRS）and 23 patients with non-eosinophilic CRSwNP（nECRS）. VAS-olfactory dysfunction （VAS-OD） score, SNOT-22 olfactory score, Sniffin' Sticks test and oERPs collection and processing were performed before the operation. All items were evaluated again 3 months after the operation. Results:VAS-OD and SNOT-22 olfactory score were significantly lower in all CRSwNP patients after the operation than those before the operation[F（1, 43） =357.429, P<0.001; F（1, 43） =185.657, P<0.001], the scores of T, D, I and TDI scores in Sniffin' Sticks test were significantly higher than those before the operation[F（1, 43） =126.302, P<0.001; F（1, 43） =311.301, P<0.001; F（1, 43） =131.401, P<0.001; F（1, 43） =295.885, P<0.001]; The decrease of VAS-OD and SNOT-22 olfactory score in the ECRS group was smaller than that in the nECRS group[F（1, 43） =4.825, P=0.033; F（1, 43） =9.916, P=0.003], T, D and TDI scores were significantly lower in nECRS group than those in nECRS group[F（1, 43） =6.719, P=0.013; F（1, 43） =4.890, P=0.032; F（1, 43） =4.469, P=0.040]; There was a positive correlation between preoperative eosinophil-to-lymphocyte ratio（ELR） and SNOT-22 olfactory score and how much it changes（r=0.455, P=0.002; r=-0.414, P=0.005）, a negative correlation between T, TDI score and how much they change respectively（r=-0.431, P=0.003; r=-0.385, P=0.009; r=-0.383, P=0.010; r=-0.316, P=0.035）. The latency of P3 was significantly shorter after operation than that before operation in all CRSwNP patients[F（1, 14） =24.840, P<0.001], however, the amplitude has no significant surgical effect. Conclusion:FESS could significantly improve the olfactory function of CRSwNP patients, while changes in plasticity may occur in the olfactory cortex. In addition, the preoperative peripheral blood eosinophil granulocyte level can predict the postoperative olfactory improvement.

Correlation between chronic sinusitis subtypes and basophil levels in peripheral blood / 临床耳鼻咽喉头颈外科杂志

Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis （CRS） subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis （eCRS） group （47 cases） and non eosinophilic chronic sinusitis （non-eCRS） group （79 cases）. The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio（bEBR）, basophils-to-neutrophils ratio（BNR）, basophils-to-lymphocytes ratio（BLR）, basophils-to-monocytes ratio（BMR） were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio（bEBR） were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio（BNR） were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio（BLR） were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio（BMR） were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group（P<0.01）, while there was no statistically significant difference between non-eCRS group and healthy control group（P>0.05）. Basophil counts （r=0.185 5, P<0.05）, BLR（r=0.226 9, P<0.05）, BMR（r=0.228 1, P<0.01） in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils（r=0.479 2, P<0.01）, lymphocytes（r=0.259 4, P<0.01）, and monocytes（r=0.256 4, P<0.01） in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

Efficacy of glucocorticoid stent implantation in ethmoid sinus after endoscopic sinus surgery for chronic rhinosinusitis with nasal polyps / 临床耳鼻咽喉头颈外科杂志

Objective:To evaluate the efficacy of glucocorticoid sinus stents implanted 2 weeks after functional endoscopic sinus surgery（FESS） for the treatment of chronic rhinosinusitis with nasal polyps（CRSwNP）. Methods:CRSwNP patients with similar bilateral lesions were randomly divided into two groups, with a stent group of 25 patients and a control group of 24 patients. Patients in the stent group had glucocorticoid sinus stents implanted into the bilateral ethmoid sinuses 2 weeks after FESS, while the control group underwent postoperative debridement only. Follow-up assessments occurred at postoperative weeks 2, 4, 8, and 12. Patients were asked to assess their sensation of nasal symptoms using a 10-point visual analog scale. Efficacy was assessed by endoscopic evaluations. Sinus obstruction, crusting/coagulation, polyp formation, middle turbinate position, adhesions, mucosa epithelialization, and postoperative intervention were assessed as efficacy outcomes. GraphPad Prism 9 was applied for statistical analysis. Results:At 4 and 8 weeks postoperatively, the stent group showed significant improvement in VAS scores of nasal congestion and runny nose compared with the control group（P<0.05）. No significant difference was observed in the VAS scores of head and facial stuffiness, loss of smell, or nasal dryness/crusting between the two groups（P>0.05）. Compared with the control group, the stent group had a lower rate of polypoid formation at 4, 8, and 12 weeks postoperatively. At postoperative week 12, the rate of mucosal epithelialization in the ethmoid cavity was significantly higher in the stent group. During the follow-up, the frequency of postoperative intervention was significantly lower in the stent group than in the control group（P<0.05）. Besides, a lower incidence of middle turbinate lateralization was found in the stent group at 8 and 12 weeks postoperatively. At 8 weeks postoperatively, the stent group had a percentage of adhesion lower than that of the control group（all P<0.05）. Conclusion:Implantation of glucocorticoid sinus stents after FESS can maintain sinus cavity patency, improve the inflammatory status of the operative cavity, reduce postoperative interventions, and promote benign regression of the operative cavity.

Symptom assessment after nasal irrigation with xylitol in the postoperative period of endonasal endoscopic surgery / Avaliação dos sintomas após irrigação nasal com xilitol no período pós-operatório de cirurgias endoscópicas endonasais

Abstract Introduction: Chronic rhinosinusitis is an inflammatory condition of the nasal cavity and the paranasal sinuses that requires multifactorial treatment. Xylitol can be employed with nasal irrigation and can provide better control of the disease. Objective: To evaluate the association between the effects of nasal lavage with saline solution compared to nasal lavage with a xylitol solution. Methods: Fifty-two patients, divided into two groups (n = 26 in the "Xylitol" group and n = 26 in the "Saline solution" group) answered questionnaires validated in Portuguese (NOSE and SNOT-22) about their nasal symptoms and general symptoms, before and after endonasal endoscopic surgery and after a period of 30 days of nasal irrigation. Results: The "Xylitol" group showed significant improvement in pain relief and nasal symptom reduction after surgery and nasal irrigation with xylitol solution (p < 0.001). The "Saline solution" group also showed symptom improvement, but on a smaller scale. Conclusion: This study suggests that the xylitol solution can be useful in the postoperative period after endonasal endoscopic surgery, because it leads to a greater reduction in nasal symptoms.

Resumo Introdução: Rinossinusite crônica é um quadro de inflamação da cavidade nasal e dos seios paranasais que necessita de tratamento multifatorial. O xilitol pode ser associado às irrigações nasais e pode prover melhor controle da doença. Objetivo: Avaliar a relação entre os efeitos da lavagem nasal com solução fisiológica em comparação à lavagem nasal com solução de xilitol. Método: Divididos em dois grupos (n = 26 no grupo Xilitol e n = 26 no grupo Soro), 52 pacientes responderam à questionários validados em língua portuguesa (NOSE e SNOT-22) sobre seus sintomas nasais e sintomas gerais, antes e depois de cirurgia endoscópica endonasal e após um período de 30 dias de irrigação nasal. Resultados: O grupo Xilitol apresentou melhoria significativa dos sintomas de dor e sintomas nasais após a cirurgia e a irrigação nasal com solução de xilitol (p < 0,001). O grupo Soro também apresentou melhoria dos sintomas, porém em menor escala. Conclusão: Este estudo sugere que a solução de xilitol pode ser usada no período pós-operatório de cirurgia endoscópica endonasal por levar a uma maior redução nos sintomas nasais.

Resultados clínicos e imagenológicos en pacientes con rinosinusitis crónica odontogénica / Evaluation of clinical and imaging results in patients with chronic odontogenic rhinosinusitis

INTRODUCCIÓN: La rinosinusitis crónica odontogénica (RSCO) es un proceso inflamatorio/infeccioso de la mucosa nasal y senos paranasales (SPN) de origen dental. Corresponde a una patología subdiagnosticada en la actualidad. El gold standard diagnóstico es la tomografia computarizada. Los tratamientos difieren, desde tratamiento médico aislado hasta médico-quirúrgico de SPN o combinados. OBJETIVO: Caracterizar los resultados clinicos e imagenológicos de pacientes con RSCO en función del tratamiento recibido, para establecer recomendaciones terapéuticas. Describir la frecuencia de subdiagnóstico de esta patología. MATERIAL Y MÉTODO: Estudio descriptivo, retrospectivo. Se incluyeron pacientes con diagnóstico clínico e imagenológico de RSCO entre los años 2013-2017 en un centro de atención médico privado, a los que se realizó una tomografía computarizada cone beam de control. Fueron excluidos aquellos con rinosinusitis crónica, cirugía endoscópica funcional (CEF) previa, cáncer, embarazadas, rechazo a tomografía computarizada cone beam, ausencia de imágenes preoperatorias y menores de 18 años. RESULTADOS: De un total de 27 pacientes, en los operados de CEF (n =24; 89%) la resolución total de los síntomas se logró en 20/24 (83%), resolución parcial 3/24 (12,5%) y persistencia de los síntomas 1/24 (4%). Discusión: De los pacientes con RSCO 22/27 (81%) no tenían reportado el foco dental en el informe radiológico a pesar de ser visible. Aquellos pacientes con sintomatologia postratamiento, hubo factores identificados como la bilateralidad, mala dentadura general, falta de combinación de tratamiento dental y CEF. CONCLUSIONES: La CEF combinada con tratamiento dental concomitante, tiene un alto grado de éxito radiológico y clínico en esta patología. No fue posible demostrar si siempre es requerida la exodoncia con cierre de fístula oro-antral o si se pueden seleccionar pacientes para un tratamiento más conservador.

INTRODUCTION: Chronic odontogenic rhinosinusitis (CORS) is an inflammatory/infectious process of the nasal mucosa and sinuses of dental origin. Actually, it corresponds to an underdiagnosed pathology. The gold standard diagnosis is computed tomography. The treatments differ, from isolated medical treatment to medical-surgical sinuses or combined. AIM: To characterize the clinical and imaging results of patients with CORS according to the treatment received, to establish therapeutic recommendations. In addition to describing the frequency of subdiagnosis of this pathology. MATERIAL AND METHOD: Descriptive, retrospective study. Patients with clinical and imaging diagnosis of CORS between 2013-2017 were included in a private medical care center, to whom a cone beam computed tomography control was performed. Those with chronic rhinosinusitis, previous functional endoscopic sinus surgery (FESS), cancer, pregnant women, rejection of cone beam computed tomography, absence of preoperative images and those under 18 years were excluded. RESULTS: Of all patients operated on FESS (n =24; 89%) the total resolution of the symptoms was 20/24 (83%), partial resolution 3/24 (12.5%) and persistence of the symptoms a 1/24 (4%). Discussion: 22/27 (81%) of patients with CORS had not reported the dental focus in the radiological report despite being visible. Those patients with post-treatment symptoms had identified factors such as bilaterality, general bad teeth, lack of combination of dental treatment and FESS. CONCLUSION: The FESS combined with concomitant dental treatment, has a high degree of radiological and clinical success in this pathology. It was not possible to demonstrate whether exodontia with closure of oroantral fistula is always required or if patients can be selected for a more conservative treatment.

Comparison of natural ostiodilatation and endoscopic sinus surgery in the same patient with chronic sinusitis / Comparação entre a dilatação do óstio natural e a cirurgia endoscópica nasossinusal no mesmo paciente com sinusite crônica

Abstract Introduction Chronic rhinosinusitis is a broad clinical syndrome characterized by mucosal inflammation of the nose and paranasal sinuses. In order for the paranasal sinuses to maintain their physiological functions; the ostiomeatal complex drainage pathways must be open. Surgical procedures are an important treatment option in patients who do not respond adequately to medical treatment. Although the methods and instruments used in functional endoscopic sinus surgery have continued to improve in recent years, the scar tissue formed during operation disrupts the drainage of the sinuses and reduces postoperative success. The natural ostiodilatation method, which is performed by balloon sinoplasty method, has become more and more popular in recent years. Objectives To compare the technique of balloon sinoplasty with the classical functional endoscopic sinus surgery method by considering the severity of chronic sinusitis on the same patient. Methods Total of 61 chronic sinusitis patients was included in the study. Paranasal sinus tomography of the patients was taken and according to the Lund-Mackay scoring, chronic sinusitis levels were determined. Cases were divided into two groups: Group 1 (severe chronic sinusitis group) and Group 2 (mild chronic sinusitis). Results There was no statistically significant difference in the results of comparison of sinuses which underwent balloon sinoplasty and classical functional endoscopic sinus surgery in Group 2 after Lund-Mackay scores. However in Group 1, the results of the comparison of postoperative Lund-Mackay scores of the balloon sinoplasty and the classical endoscopic operation were statistically significantly lower than those of the face half operated with the classical functional endoscopic sinus surgery. Conclusion The success of balloon sinoplasty in patients with mild sinusitis is the same as in classic functional endoscopic sinus surgery. However, as the severity of sinusitis increases, the efficacy of balloon sinoplasty decreases.

Resumo Introdução A rinossinusite crônica é uma síndrome clínica ampla, caracterizada por inflamação da mucosa nasal e seios paranasais. Para que os seios paranasais mantenham suas funções fisiológicas, as vias de drenagem do complexo ostiomeatal devem estar abertas. Os procedimentos cirúrgicos são uma importante opção de tratamento em pacientes que não respondem adequadamente ao tratamento clínico. Embora os métodos e instrumentos utilizados na cirurgia endoscópica funcional dos seios paranasais tenham melhorado continuamente, o tecido cicatricial formado durante a cirurgia interrompe a drenagem dos seios nasais e reduz o sucesso pós-operatório. O método natural de dilatação ostial, que é aplicado por meio da técnica de sinuplastia com balão, tem se tornado cada vez mais popular nos últimos anos. Objetivos Comparar a técnica de sinuplastia com balão com o método convencional de cirurgia endoscópica, no mesmo paciente, considerando a gravidade da rinossinusite crônica. Método Foram incluídos no estudo 61 pacientes com rinossinusite crônica. Por meio de tomografia dos seios paranasais e de acordo a escala de Lund-Mackay foram determinados os graus da rinossinusite crônica. Os casos foram divididos em dois grupos: Grupo 1 (grupo com rinossinusite crônica grave) e Grupo 2 (rinossinusite crônica leve). Resultados No Grupo 2 não houve diferença estatisticamente significante, segundo a escala de Lund-Mackay, no resultado da comparação dos seios paranasais nos quais foram realizadas a sinuplastia com balão e por cirurgia endoscópica convencional. No entanto, no Grupo 1, os resultados da comparação dos escores pós-operatórios de Lund-Mackay mostraram-se estatística e significativamente melhores naqueles submetidos à cirurgia endoscópica funcional dos seios paranasais. Conclusão O sucesso da sinuplastia com balão em pacientes com rinossinusite leve é o mesmo da cirurgia endoscópica funcional dos seios da face tradicional. No entanto, à medida que a gravidade da rinossinusite aumenta, a eficácia da sinuplastia com balão diminui.

Systematic review of the literature on surgical treatment of chronic rhinosinusitis in children: what is the best approach? / Revisão sistemática da literatura no tratamento cirúrgico da rinossinusite crônica na infância: qual a melhor abordagem?

ABSTRACT Objective: To carry out a systematic literature review on the surgical treatment of chronic rhinosinusitis in the pediatric population. Data sources: A bibliographic review methodology was used, based on data from National Library of Medicine (Medline), PubMed, Latin American and Caribbean Health Sciences Literature (LILACS) and Scientific Electronic Library Online (SciELO), of the indexed works from 2006 to 2016, including the pediatric population from zero to 13 years of age. The search keywords according to Medical Subject Heading (MESH) and Health Sciences Descriptors (DeCS) were: child, surgery, sinusitis and chronic disease. A total of 318 articles were collected, five of which met the inclusion criteria and were used as a basis for this review. All articles were prospective cohort studies, level of evidence 2B, according to the criterion used by evidence-based medicine. Data synthesis: The literature agreed that the next step for the cases refractory to drug treatment in chronic rhinosinusitis in childhood would be surgery. Adenoidectomy would be the initial method, for the safety of the procedure and improvement in about 50% of the cases, although more significant results were found in patients who associated this procedure with facial sinus surgery. Conclusions: Surgical treatment should be indicated for chronic rhinosinusitis in childhood after treatment failure. The results pointed out that adenoidectomy, when associated with some type of approach to the facial sinus, present better results.

RESUMO Objetivo: Realizar uma revisão sistemática da literatura sobre o tratamento cirúrgico da rinossinusite crônica na população pediátrica. Fonte de dados: Utilizou-se metodologia de revisão bibliográfica, por meio de levantamentos nas bases de dados científicas National Library of Medicine (Medline), PubMed, Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Electronic Library Online (SciELO), dos trabalhos indexados no período entre 2006 e 2016, incluindo a população pediátrica de zero a 13 anos. Os descritores de busca, segundo o Medical Subject Heading (MESH) e os Descritores em Ciências da Saúde (DeCS), foram: Child, Surgery, Sinusitis e Chronic Disease. Foram levantados 318 artigos, dos quais cinco preencheram os critérios de inclusão e foram usados como base para esta revisão. Todos os artigos foram estudos de coorte prospectivos, nível de evidência 2B, segundo critério usado pela medicina baseada em evidências. Síntese dos dados: Foi consenso na literatura que, para os casos refratários ao tratamento medicamentoso na rinossinusite crônica na infância, o próximo passo seria a cirurgia. A adenoidectomia seria o método inicial, pela segurança do procedimento e pela melhora em cerca de 50% dos casos, embora resultados mais significativos terem sido encontrados em pacientes que associaram esse procedimento à cirurgia dos seios da face. Conclusões: O tratamento cirúrgico pode ser indicado na rinossinusite crônica na infância após falha terapêutica. Os resultados apontaram que a adenoidectomia, quando associada a algum tipo de abordagem aos seios, apresenta melhores resultados.

Lacrimal Diversion Devices (Sinopsys Lacrimal Stent): Sharing our Experience with Patients with Chronic Rhinosinusitis without Polyposis

Introduction: Chronic rhinosinusitis (CRS) is a highly prevalent pathology in our society. Due to the prevalence of this condition and to the persisting symptoms despite an appropriate medical treatment, surgical techniques are often required. Lately, minimal invasive techniques have been described, such as lacrimal diversion devices (LDDs). This technique offers a fast and convenient choice for delivery of sinus irrigation and topical medication. Objective: We aimed to describe our experience with LDDs and evaluate the safety and effectiveness of the procedure in patients with moderate to severe CRS without nasal polyposis (CRSsNP) and persistent symptomatology despite medical therapy. Methods: A total of 7 patients underwent bilateral lacrimal stents placement in the operating room. A retrospective observational study was conducted. The Sino-Nasal Outcome Test-20 (SNOT-20) survey was performed and the score obtained was compared before and 1 month after the procedure. Results: The LDDs were used for an average of 80 days. During the follow-up, only three patients had a mild complication with the device (granuloma in the punctum, obstruction, and early extrusion). The mean baseline SNOT-20 score dropped significantly ( p = 0.015) from 25.85 to 11.57 (mean: - 14.29) 1 month after the procedure. Conclusion: According to our experience and results, the use of LDD is a novel, feasible, and less invasive technique to treat refractory CRS. It reduces the risk of mucosal stripping, provides short-term outcomes, and the surgical procedure does not require advanced training in endoscopic sinus surgery. Moreover, it can be performed in-office under local anesthesia or sedation (AU)

Sleep quality assessment in chronic rhinosinusitis patients submitted to endoscopic sinus surgery: a meta-analysis / Avaliação da qualidade do sono em pacientes com rinossinusite crônica submetidos à cirurgia endoscópica nasossinusal: uma meta-análise

Abstract Introduction: Chronic rhinosinusitis can lead to poor sleep quality in affected individuals. Endoscopic nasal surgery has been indicated for patients with chronic rhinosinusitis, resulting in improved quality of life, but it is still unknown if there is a similar improvement in sleep quality after the surgical procedure. Objective: To estimate the sleep quality of patients with chronic rhinosinusitis after undergoing endoscopic sinus surgery. Methods: The literature search was conducted in the indexed databases PubMed, Embase, Lilacs, SciELO, Google Scholar, Web of Science, Scopus, Database of Thesis and Dissertations of CAPES, Cochrane Library, Clinical Trials and in the grey literature. It included studies that reported the sleep quality of patients with chronic rhinosinusitis after undergoing endoscopic sinus surgery based on questionnaires assessing quality of life. Two researchers independently conducted the study selection and extraction. The random effects model was chosen to conduct the meta-analysis that was performed using the statistical package STATA, version 11. Results: Overall, 4 studies and 509 subjects were included in the systematic review. Improved sleep quality was observed in 90% of the patients. There was an improvement (on average, from 57% to 67%) in each of the five symptoms related to sleep quality. The results of the meta-analysis revealed high heterogeneity. Conclusions: This review shows that a large percentage of patients report improved sleep quality after endoscopic sinus surgery.

Conclusões: Esta revisão mostra que uma grande porcentagem de indivíduos relata melhoria na qualidade do sono após a cirurgia endoscópica nasossinusal.

Use of the long-term quality of life assessment in the decision to indicate surgery in patients with chronic rhinosinusitis / Uso da avaliação da qualidade de vida em longo prazo na decisão de indicação cirúrgica em pacientes com rinossinusite crônica

Abstract Introduction: Quality-of-life questionnaires have been used to support decision-making in patients with chronic rhinosinusitis in the past decade. The choice of treatment in practice, however, also considers the patient's decision. Objective: To assess the long-term quality of life of patients with chronic rhinosinusitis who decided to avoid surgery. Methods: This is a prospective longitudinal study with a group of patients with chronic rhinosinusitis, with and without indication for surgery, with application of the questionnaire SNOT-22 in two periods: between 2011 and 2012 and between June and August 2016, via email. Results: Data were collected from 42 patients, of which 13 presented indications for surgery and 29 were not indicated for surgery. The average quality of life score was 42.1 (±16.4) in the group with an indication for surgery and 40.6 (±23.4) in the group without this indication, p = 0.84. All the patients were assessed by a single doctor with blinding in relation to the initial score. No differences were detected between the groups. The impact of the chronic rhinosinusitis was reduced even among the patients with the indication for surgery. Both groups scored over 40. Conclusion: This study can help predict the impact of the chronic rhinosinusitis over time and better adjust expectations with non-surgical treatment.

Resumo Introdução: Questionários de qualidade de vida têm sido usados na última década para apoiar a tomada de decisão em pacientes com rinossinusite crônica. Entretanto, na prática, a escolha do tratamento também considera a decisão do paciente. Objetivo: Avaliar a qualidade de vida em longo prazo de pacientes com rinossinusite crônica que decidiram não se submeter à cirurgia. Método: Estudo longitudinal prospectivo com um grupo de pacientes com rinossinusite crônica, com e sem recomendação de cirurgia, com aplicação do questionário Sino-Nasal Outcome Test 22 (SNOT-22, teste de desfecho sinonasal) em dois períodos: entre 2011 e 2012 e entre junho e agosto de 2016, via e-mail. Resultados: Foram coletados dados de 42 pacientes, dos quais 13 tiveram recomendação para cirurgia e 29 não tiveram. O escore médio de qualidade de vida foi de 42,1 (± 16,4) no grupo com indicação de cirurgia e de 40,6 (± 23,4) no grupo sem essa indicação, p = 0,84. Todos os pacientes foram avaliados por um único médico, cegado para o escore inicial. Não foram detectadas diferenças entre os grupos. O impacto da rinossinusite crônica foi reduzido mesmo entre os pacientes com indicação de cirurgia. Ambos os grupos apresentaram um escore acima de 40. Conclusão: Este estudo pode ajudar a prever o impacto da rinossinusite crônica ao longo do tempo e ajustar de forma mais adequada as expectativas com o tratamento não cirúrgico.

Steroid vs. antibiotic impregnated absorbable nasal packing for wound healing after endoscopic sinus surgery: a randomized, double blind, placebo-controlled study / Tampão nasal absorvível embebido em esteroides versus antibióticos para cicatrização de feridas após cirurgia endoscópica nasossinusal: estudo randomizado, duplo cego, placebo controlado

Abstract Introduction: Endoscopic sinus surgery can lead to crusting or synechiae formation, which can affect the healing process. Objective: The aim of our study was to compare the influence of steroid versus antibiotic versus saline solution impregnated absorbable nasal spacers on postoperative wound healing and patient satisfaction. Methods: Eighty patients, 33 women and 47 men, were enrolled in this study. At the end of the surgery, two pieces of 4 cm biodegradable material were applied in each ethmoid cavity. One of them was impregnated with saline solution, while the second one with steroid, or with antibiotic. Results: We observed statistically significant differences in the Lund-Kennedy score between the control and both treatment groups: for the Antibiotic-group on days 10 and 30 (p = 0.009; p = 0.009) and for the Steroid-group on day 90 (p = 0.008). The extended endoscopic appearance of nasal mucosa indicated statistically significant differences in crust formation on day 10 comparing the steroid and control dressing (p = 0.025), in secretion type on days 10 and 30 comparing the antibiotic and control dressing (p = 0.003; p = 0.016) and additionally for steroid and control on day 90 (p = 0.046). On Day 90 we observed statistically significant differences in the absence of mucosal edema in the S-group compared to controls (p = 0.007). Conclusions: The results of this study reveal the significant positive influence of steroid- and antibiotic-impregnated biodegradable nasal packing on the postoperative healing process and patient satisfaction compared to the saline soaked dressing.

Resumo Introdução: A cirurgia endoscópica nasossinusal pode levar à formação de crostas e sinéquias, o que pode afetar o processo de cicatrização. Objetivo: O objetivo do nosso estudo foi comparar a influência do espaçador nasal absorvível embebido em esteroide versus antibiótico versus solução salina na cicatrização de ferida pós-operatória e na satisfação do paciente. Método: Oitenta pacientes, 33 mulheres e 47 homens, foram incluídos neste estudo. Ao final da cirurgia, dois tampões de material biodegradável de 4 cm foram aplicados em cada cavidade etmoidal. Um deles foi embebido em solução salina, enquanto no segundo foi utilizado esteroide, ou antibiótico. Resultados: Observamos diferenças estatisticamente significantes no escore de Lund-Kennedy entre os grupos controle e ambos os grupos tratamentos: para o grupo antibiótico nos dias 10 e 30 (p = 0,009; p = 0,009) e para o grupo esteroide no dia 90 (p = 0,008). O aspecto endoscópico da mucosa nasal indicou diferenças estatisticamente significantes na formação de crostas no dia 10, na comparação do esteroide com o curativo controle (p = 0,025), no tipo de secreção nos dias 10 e 30, na comparação do antibiótico com o curativo controle (p = 0,003; p = 0,016) e adicionalmente para esteroide e controle no dia 90 (p = 0,046). No dia 90, observamos diferenças estatisticamente significantes na ausência de edema da mucosa no grupo E (esteroide) em relação aos controles (p = 0,007). Conclusões: Os resultados deste estudo revelam uma influência positiva significante no uso de tampão nasal biodegradável embebido em esteroides e antibióticos no processo de cicatrização pós-operatória e satisfação do paciente em comparação com o curativo embebido em solução salina.

Postoperative Management of Eosinophilic Chronic Rhinosinusitis with Nasal Polyps: Impact of High-Dose Corticosteroid Nasal Spray

Abstract Introduction Eosinophilic chronic rhinosinusitis (ECRS) is characterized by an eosinophilic inflammation driven by Th2-type cytokines. Glucocorticosteroids are the most common first-line treatment for ECRS with nasal polyps. Objective We have evaluated the long-term treatment with double-dose intranasal corticosteroids in refractory ECRS nasal polyps resistant to the conventional dose and assessed the risk of adverse systemic effects Methods Sixteen subjects were enrolled in this study. All subjects had ECRS after endoscopic sinus surgery that resulted in recurrentmild andmoderate nasal polyps and were undergoing a postoperative follow-up application of mometasone furoate at a dose of 2 sprays (100 μg) in each nostril once a day (200 μg). All the patients were prescribed mometasone furoate, administered at a dose of 2 sprays (100 μg) in each nostril twice a day (400 μg) for 6 months. Results The average scores of the symptoms during the regular dose of intranasal steroid treatment were 5.2 ± 2.2, but 6 months after the high-dose application, they had significantly decreased to 2.5 ± 1.4 (p < 0.05). The polyp size showed an average score of 1.38 during the regular dose which was significantly reduced to 0.43 (p < 0.01) by the double dose. Glycated hemoglobin (HbA1c) showed normal ranges in all the patients tested. The cortisol plasma concentration was also normal. Conclusion Doubling the dose of the nasal topical spray mometasone furoate might be recommended for the treatment of recurrent nasal polyps in the postoperative follow-up of intractable ECRS. (AU)

Can we use the questionnaire SNOT-22 as a predictor for the indication of surgical treatment in chronic rhinosinusitis? / Podemos usar o questionário SNOT-22 como preditor para a indicação de tratamento cirúrgico na rinossinusite crônica?

Abstract Introduction: Chronic rhinosinusitis is a prevalent disease that has a negative impact on the lives of sufferers. SNOT-22 is considered the most appropriate questionnaire for assessing the quality of life of these patients and a very effective method of evaluating therapeutic interventions; however it is not used as a tool for decision-making. Objective: To test the hypothesis that the SNOT-22 score can predict the outcome of surgical treatment. Methods: A retrospective, longitudinal and analytical study. We evaluated the medical records of patients with chronic rhinosinusitis that completed the SNOT-22 at the time of diagnosis. All the patients were consecutively receiving care at an otolaryngology service in Salvador, Bahia from August 2011 to June 2012. The outcomes of the surgical treatment of these patients were obtained from their medical records. The initial score was compared to a group of patients who were not referred for surgery. All the patients completed and signed a consent form. Results: Of the 88 patients with chronic rhinosinusitis, 26 had evolved to surgery over the last 3 years. The groups were homogeneous regarding gender and respiratory and medication allergies. The patients of the surgical group were 44.8 + 13.8 years old and the patients of the clinical group were 38.2 + 12.5 years old (p = 0.517). The average SNOT-22 score of the case group was 49 + 19 and the average score of the control group was 49 + 27 (p = 0.927). Conclusion: The SNOT-22 was unable to predict the outcome of surgical patients with chronic rhinosinusitis.

Resumo Introdução: A rinossinusite crônica é uma doença prevalente que tem um impacto negativo sobre a vida dos portadores. O SNOT-22 é considerado o questionário mais adequado para avaliar a qualidade de vida desses pacientes e um método muito eficaz de avaliar intervenções terapêuticas; no entanto, ele não é usado como uma ferramenta para a tomada de decisões. Objetivo: Testar a hipótese de que o escore do SNOT-22 pode prever o desfecho do tratamento cirúrgico. Método: Estudo retrospectivo, longitudinal e analítico. Foram avaliados os prontuários de pacientes com rinossinusite crônica que preencheram o SNOT-22 no momento do diagnóstico. Todos os pacientes foram consecutivamente atendidos em um serviço de otorrinolaringologia em Salvador, Bahia, de agosto de 2011 a junho de 2012. Os desfechos do tratamento cirúrgico desses pacientes foram obtidos a partir de seus prontuários médicos. A pontuação inicial foi comparada com um grupo de pacientes que não foi encaminhado para cirurgia. Todos os pacientes preencheram e assinaram um termo de consentimento informado. Resultados: Dos 88 pacientes com rinossinusite crônica 26 evoluíram para cirurgia nos últimos três anos. Os grupos foram homogêneos quanto a sexo, alergias respiratórias e medicamentos. Os pacientes do grupo cirúrgico tinham 44,8 + 13,8 anos e os do grupo clínico tinham 38,2 + 12,5 (p = 0,517). O escore médio do SNOT-22 do grupo do caso foi de 49 + 19 e o do grupo controle foi de 49 + 27 (p = 0,927) Conclusão: O SNOT-22 foi incapaz de prever o desfecho dos pacientes cirúrgicos com rinossinusite crônica.

We describe the case of a female patient of 66 years old, who consulted for having cacosmia, left facial pain and purulent rhinorrhea, after left second molar extraction. CT-scan sinus showed the total left maxillary sinus, partial left ethmoid opacity and bone defect in left alveolar ridge. A vomer bone graft was taken from the nasal septum; left maxillary sinus surgerywas done by endoscopic approach and intraoral closure of bony and mucosa fístula was concluded.

Ophthalmic complications of endoscopic sinus surgery / Complicações oftálmicas da cirurgia endoscópica dos seios nasais

Abstract Introduction: The proximity of the paranasal sinuses to the orbit and its contents allows the occurence of injuries in both primary or revision surgery. The majority of orbital complications are minor. The major complications are seen in 0.01-2.25% and some of them can be serious, leading to permanent dysfunction. Objective: The aim of this study was to determine the risk and type of ophthalmic complications among patients operated due to a chronic rhinosinusitis. Methods: This is a retrospective study of 1658 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with or without polyps or mucocele. Surgeries were performed under general anesthesia in all cases and consisted of polyps' removal, followed by middle metal antrostomy, partial or complete ethmoidectomy, frontal recess surgery and sphenoid surgery if necessary. The ophthalmic complications were classified according to type, frequency and clinical findings. Results: In our material 32.68% of the patients required revision surgery and only 10.1% had been previously operated in our Department. Overall complications occurred in 11 patients (0.66%). Minor complications were observed in 5 patients (0.3%) with the most frequent being periorbital ecchymosis with or without emphysema. Major complications were observed in one patient (0.06%) and were related to a lacrimal duct injury. Severe complications occurred in 5 cases (0.3%), with 2 cases and referred to a retroorbital hematoma, optic nerve injury (2 cases) and one case of extraocular muscle injury. Conclusions: Orbital complications of endoscopic nasal surgery are rare. The incidence of serious complications, causing permanent disabilities is less than 0.3%. The most important parameters responsible for complications are extension of the disease, previous endoscopic surgery and coexisting anticoagulant treatment.

Resumo Introdução: A proximidade dos seios paranasais à órbita e seu conteúdo tornam possível a ocorrência de lesões tanto na cirurgia primária como na de revisão. A maioria das complicações orbitais são menores. As maiores são observadas em 0,01%-2,25% e algumas delas podem ser graves levando a disfunção permanente. Objetivo: O objetivo deste estudo foi identificar o risco e o tipo de complicações oftalmológicas em pacientes operados devido a rinossinusite crônica. Método: Foi realizado um estudo retrospectivo com 1.658 pacientes submetidos a cirurgia endoscópica sinusal devido a rinossinusite crônica com ou sem pólipos ou mucocele. As cirurgias foram realizadas sob anestesia geral em todos os casos e consistiram de remoção de pólipos, seguida de antrostomia meatal média ou etmoidectomia parcial ou completa, cirurgia de recesso frontal e cirurgia de esfenoide se necessário. As complicações oftalmológicas foram classificadas de acordo com o tipo, frequência e achados clínicos. Resultados: Em nosso material 32,68% dos pacientes necessitaram de cirurgia de revisão e apenas 10,1% haviam sido anteriormente operados em nosso departamento. As complicações gerais ocorreram em 11 pacientes (0,66%). Complicações menores foram observadas em 5 pacientes (0,3%), sendo que a mais frequente foi equimose periorbital com ou sem enfisema. Complicações maiores foram observadas em um paciente (0,06%) e atribuída à lesão do ducto lacrimal. Complicações graves ocorreram em 5 casos (0,3%) e foram referidas como hematoma retrorbital (2 casos), lesão do nervo óptico (2 casos) e um caso de lesão muscular extraocular. Conclusões: As complicações orbitais da cirurgia endoscópica nasal são raras. A incidência de complicações graves que causam incapacidade permanente é de menos de 0,3%. Os parâmetros mais importantes responsáveis por complicações são extensão da doença, cirurgia endoscópica anterior e tratamento anticoagulante coexistente.

Clinical outcome and patient satisfaction using biodegradable (NasoPore) and non-biodegradable packing, a double-blind, prospective, randomized study / Desfecho clínico e satisfação do paciente com o uso de tampão biodegradável (NasoPore) e não biodegradável: estudo prospectivo, duplo-cego e randomizado

Abstract Introduction Nasal packing after endoscopic sinus surgery is used as a standard procedure. The optimum solution to minimize or eliminate all disadvantages of this procedure may be accomplished using biodegradable packs. Objective The aim of this study was to compare patient satisfaction and clinical outcome associated with absorbable and non-absorbable packing after FESS. Methods In total, 50 patients were included in a prospective, double-blind, randomized trial. One side was packed with polyurethane foam, while the opposite side was packed with gauze packing. On the 2nd, 10th, and 30th postoperative day, the patients were questioned with the aid of a visual analog scale. The standardized questionnaires for bleeding, nasal breathing, feeling of pressure, and headache were used. The presence of synechiae, infection, or granulation was noted and recorded with the video-endoscopy. Results A significant difference according to lower pressure was found in the NasoPore group compared to the controls on day ten after surgery. The NasoPore packing had lower scores with respect to postoperative nose blockage on the 2nd and 10th days. Mucosal healing was better for the NasoPore group, both at day ten and 30 compared with the control group. Conclusion The overall patient comfort is higher when using NasoPore compared to non-resorbable traditional impregnated gauze packing. Intensive saline douches applied three to four times per day are mandatory after the operation to prevent synechiae formation and fluid resorption by the packing.

Resumo Introdução O tamponamento nasal após cirurgia sinusal endoscópica é procedimento de rotina. A solução ideal para minimizar ou eliminar as desvantagens desse procedimento pode ser alcançada com o uso de tampões biodegradáveis. Objetivo Comparar a satisfação do paciente e o desfecho clínico associados ao uso de tampões absorvíveis e não absorvíveis após a cirurgia funcional dos seios paranasais (FESS- Functional Endoscopic Sinus Surgery). Método Foram incluídos 50 pacientes neste estudo prospectivo, duplo-cego e randomizado. Um dos lados foi tamponado com espuma de poliuretano, enquanto no outro lado foi feito um tamponamento com gaze. Nos 2º, 10º e 30º dias após a operação, os pacientes foram perguntados com a ajuda de uma escala analógica visual. Foram empregados questionários padronizados para sangramento, respiração nasal, sensação de pressão e cefaleia. A presença de sinequias, infecção ou granulação foi registrada por videoendoscopia. Resultados Foi observada diferença significante, da sensação de pressão, menor no lado tratado com NasoPore vs. controles no 10º dia após a cirurgia. O tamponamento com NasoPore obteve escores mais baixos com respeito ao bloqueio nasal pós-operatório no 2º e 10º dias. A cicatrização da mucosa foi melhor no lado do NasoPore, mas no 10º e 30º dias os resultados foram comparáveis com os do lado de controle. Conclusão O conforto geral do paciente é maior com o uso de NasoPore vs. tamponamento tradicional com gaze besuntada não reabsorvível. O uso vigoroso de jatos de solução salina aplicados 3-4 vezes ao dia é um procedimento obrigatório após a cirurgia, para evitar a formação de sinequias e para uma absorção natural do tampão.

This article reviews about the indications and alternatives of endoscopic nasal surgery for chronic rhinosinusitis in patients with cystic fibrosis. Searches were performed in PubMed, Cochrane Library, and SciELO with a publication date until 2014, specifically chronic rhinosinusitis associated with cystic fibrosis.

The Portuguese version of the RhinoQOL Questionnaire: validation and clinical application, / Versão portuguesa do Questionário RhinoQOL: validação e aplicação clínica

ABSTRACT INTRODUCTION: Rhinosinusitis constitutes an important health problem, with significant interference in personal, professional, and social functioning. This study presents the validation process of the Portuguese version of the RhinoQOL, to be used as a routine procedure in the assessment of patients with chronic rhinosinusitis. OBJECTIVE: To demonstrate that the Portuguese version of the RhinoQOL is as valid as the English version to measure symptoms and health-related quality of life in chronic rhinosinusitis. METHODS: The Portuguese version of the RhinoQOL was administered consecutively to 58 patients with chronic rhinosinusitis with and without nasal polyps, assessed for endoscopic sinus surgery. A follow-up survey was completed three months after surgery. Statistical analysis was performed to determine its psychometric properties. RESULTS: Face and content validity were confirmed by similar internal consistency as the original questionnaire for each sub-scale, and strong correlation between individual items and total score. The questionnaire was easy and quick to administer (5.5 min). At three months, there was a significant decrease from baseline for all sub-scale scores, indicating clinical improvement, with an effect size considered as large. CONCLUSION: This study provides a questionnaire that is equivalent to the original English version, with good responsiveness to change, which can be especially valuable to measure the outcome of surgery.

RESUMO INTRODUÇÃO: A rinossinusite constitui um importante problema de saúde, com interferência significante na vida pessoal, e sócio-profissional dos pacientes. Este estudo apresenta o processo de validação da versão do RhinoQOL na língua portuguesa para ser usado em pacientes portadores de rinossinusite crônica. OBJETIVO: Demonstrar que a versão do RhinoQOL na língua portuguesa é tão válida quanto a versão inglesa na medição dos sintomas e qualidade de vida dos pacientes com rinossinusite crônica. MÉTODO: A versão em português do RhinoQOL foi aplicada consecutivamente a 58 pacientes com rinossinusite crônica, com e sem pólipos nasais, previamente à cirurgia endoscópica nasal, tendo sido reavaliados aos 3 meses de pós-operatório. Análise estatística foi realizada para determinar as suas propriedades psicométricas. RESULTADO: A validade de conteúdo foi confirmada por uma consistência interna similar à do questionário original, para cada sub-escala, e por uma forte correlação entre cada item e o score total. A aplicação do questionário foi fácil e rápida (5,5 min). Aos 3 meses, verificou-se uma redução significativa dos scores de todas as sub-escalas, indicando melhoria clínica, com um tamanho de efeito considerado grande. CONCLUSÃO: Este estudo fornece um questionário que é equivalente à versão original, com boa sensibilidade à mudança, o que pode ser especialmente útil na medição do impacto da cirurgia.
