Effect of infiltrating nasal packing with local anesthetics in postoperative pain and anxiety following sinonasal surgeries: a systemic review and meta-analysis / Efeito do tamponamento nasal infiltrado com anestésicos locais na dor e ansiedade pós-operatórias após cirurgias nasosinusais: revisão sistêmica e metanálise

Abstract Introduction: Packing of the nasal cavity has traditionally been used for postoperative bleeding control and decreasing synechia formation in patients undergoing nasal surgeries. Although absorbable nasal packing has been gaining popularity in the recent years, nonabsorbable nasal packing is still often used in nasal surgeries in various parts of the world. It is known to be associated with pain and discomfort especially upon and during removal, and previous reviews have only evaluated the effects of local anesthetic infiltration of nasal packing in septal surgeries. Objective: To evaluate the effect of infiltrating nasal packing with local anesthetics in postoperative pain and anxiety following sinonasal surgeries Materials and methods: We searched the PubMed and Embase databases from their earliest record to April 27, 2019, randomized controlled trials and prospective controlled trials for review, and included only randomized controlled trials for data analysis. We included studies using topical anesthetics-infiltrated nasal packing following sinonasal surgeries and evaluated the effectiveness compared to placebo packing in pain reduction during postoperative follow up, as well as the effectiveness in anxiety reduction. Results: Among 15 studies included for review, 9 studies involving 765 participants contributed to the meta-analysis. In terms of pain reduction, our analysis showed significant standard mean differences regarding effectiveness at postoperative 1, 12, 24 h interval for all surgical groups combined, in the sinus surgery group, as well as during nasal packing removal. There was no consistent evidence to support the effectiveness in anxiety reduction. Conclusions: Our study supports anesthetics infiltration of nasal packing as an effective method in managing pain in patients with nasal packing after sinonasal surgeries. However, the level of evidence is low. More high-quality randomized controlled trials are needed to establish its effectiveness in reducing anxiety. We believe this review is of great clinical significance due to the vast patient population undergoing sinonasal surgeries. Postoperative local hemorrhage remains the greatest concern for ear nose and throat surgeons due to the rich vasculature of the nose and sinuses. Sinonasal packing provides structural support and serves as an important measure for hemostasis and synechia formation. Although absorbable packing has been gaining popularity in the recent years, nonabsorable packing materials are still used in many countries due to lower cost. Infiltration of nasal packing with local anesthetic provides a solution to the discomfort, nasal pressure and nasal pain experienced commonly by the patients as evidenced by our analysis.

Resumo Introdução: O tamponamento da cavidade nasal tem sido usado tradicionalmente para controle do sangramento pós-operatório e diminuição da formação de sinéquia em pacientes submetidos a cirurgias nasais. Embora o tamponamento nasal absorvível tenha ganhado popularidade nos últimos anos, o tampão nasal não absorvível ainda é frequentemente usado em várias partes do mundo. Sabe-se que o tamponamento está associado a dor e desconforto, especialmente na sua remoção, e revisões anteriores avaliaram apenas os efeitos do tampão com anestésico local em cirurgias do septo nasal. Objetivo: Avaliar o efeito do tamponamento nasal infiltrado com anestésicos locais na dor e ansiedade pós-operatórias após cirurgias nasosinusais. Material e métodos: Para a revisão, pesquisamos nos bancos de dados PubMed e Embase desde o registro mais antigo até 27 de abril de 2019, incluímos ensaios clínicos controlados e randomizados, a ensaios clínicos prospectivos controlados e apenas ensaios clínicos controlados e randomizados para análise de dados. Incluímos estudos que usaram tamponamento nasal infiltrado com anestésicos tópicos após cirurgias nasosinusais e avaliamos a eficácia em comparação com o tamponamento com placebo na redução da dor durante o acompanhamento pós-operatório, bem como os efeitos na redução da ansiedade. Resultados: Entre os 15 estudos incluídos, 9, que envolveram 765 participantes, contribuíram para a metanálise. Em termos de redução da dor, nossa análise mostrou diferenças médias padrão significantes em relação à eficácia no pós-operatório nos intervalos de 1, 12, 24 horas para todos os grupos cirúrgicos combinados, no grupo da cirurgia sinusal e durante a remoção do tamponamento nasal. Não houve evidências consistentes para apoiar a eficácia na redução da ansiedade. Conclusões: Nosso estudo apoia o uso de tamponamentos nasais infiltrados com anestésicos locais como um método eficaz no tratamento da dor em pacientes após cirurgias nasosinusais. No entanto, o nível de evidência é baixo. São necessários mais ensaios clínicos randomizados de alta qualidade para estabelecer sua eficácia na redução da ansiedade. Acreditamos que esta revisão seja de grande significado clínico devido à vasta população submetida a cirurgias nasosinusais. A hemorragia local pós-operatória continua a ser a maior preocupação para os cirurgiões otorrinolaringológicos devido à rica vasculatura do nariz e seios nasais. O tamponamento nasosinusal fornece suporte estrutural e serve como uma medida importante para a hemostasia e formação de sinéquias. Embora o tamponamento absorvível tenha ganhado popularidade nos últimos anos, os materiais de tamponamento não absorvíveis ainda são usados em muitos países devido ao menor custo. A infiltração do tamponamento nasal com anestésicos locais fornece uma solução para desconforto, pressão e dor nasal comumente referida pelos pacientes, como evidenciado por nossa análise.

Reconstrucción nasal compleja con colgajo frontal y nasolabial / Complex Nasal Reconstruction with Frontal and Nasolabial Flap

RESUMEN Introducción: La reconstrucción nasal con colgajo frontal es frecuente en pacientes de edad avanzada, por lo general de causa oncológica. Con frecuencia se requieren otras técnicas complementarias, cuando los defectos comprometen varias subunidades nasales. Por lo que, reconstruir la nariz en pacientes jóvenes constituye siempre un gran desafío al cirujano plástico, por su repercusión social y la baja autoestima que afecta a estos pacientes. Objetivo: Mostrar las técnicas quirúrgicas empleadas en la reconstrucción nasal de un caso complejo, en el Instituto Nacional de Oncología y Radiobiología de Cuba. Caso clínico: Paciente masculino de 25 años de edad, con antecedentes de salud hasta sufrir un accidente por caída de una bicicleta, que ocasionó la amputación de la punta nasal y parte del ala nasal izquierda, con daño en los cartílagos alares. Conclusiones: La reconstrucción nasal con colgajo frontal y colgajo nasogeniano doblado sobre sí mismo, constituyen una adecuada herramienta quirúrgica del cirujano plástico para reconstruir defectos oncológicos y traumáticos(AU)

ABSTRACT Introduction: Nasal reconstruction with frontal flap is frequent in elderly patients, usually for oncological cause. Other complementary techniques are often required when the defects involve several nasal subunits. Therefore, nose reconstruction in young patients is always a great challenge for the plastic surgeon, due to its social repercussions and the low self-esteem affecting these patients. Objective: To show the surgical techniques used in the nasal reconstruction of a complex case, at the National Institute of Oncology and Radiobiology of Cuba. Clinical case: 25-year-old male patient, with a medical history until he suffered an accident due to a fall off a bicycle, which provoked the amputation of the nasal tip and part of the left nasal wing, with damage to the ala cartilages. Conclusions: Nasal reconstruction with frontal flap and nasolabial flap folded on itself constitute an adequate surgical tool for the plastic surgeon to reconstruct oncological and traumatic defects(AU)

Atresia congénita bilateral de coanas en una adolescente: reporte de un caso / Congenital bilateral choanal atresia in an adolescelent: a case report

La atresia congénita de coanas se caracteriza por la presencia de placas que obliteran la comunicación entre la cavidad nasal y la nasofaringe desde el nacimiento. Se considera como incompatible con la vida cuando la condición es bilateral. El siguiente es el caso de una paciente femenina, de 17 años, sin síndromes asociados, con obstrucción y descarga nasal anterior bilateral, asociado a respiración oral desde el periodo neonatal. El diagnóstico de atresia bilateral de coanas fue confirmado por medio de endoscopía nasal y tomografía computarizada (TC). La imagen confirmó la presencia de placas atrésicas de composición mixta. La paciente recibió tratamiento quirúrgicamente por vía transnasal con resección de las placas y modelado de neocoana.

Congenital choanal atresia is characterized by the presence of plates obliterating the communication between the nasal cavity and the nasopharynx from birth. If bilateral, this condition is incompatible with life. This following is the case of a 17-year-old female patient, without associated syndromes, with bilateral nasal obstruction and anterior discharge, associated to oral breathing, starting in her neonatal period. The diagnosis of bilateral choanal atresia was confirmed by nasal endoscopy and computed tomography (CT) scan, due to the presence of atretic plates of mixed composition. The patient was surgically treated with plate resection and modeling of a neochoana by means of a transnasal surgical approach.

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.

Does topical application of tranexamic acid reduce intraoperative bleeding in sinus surgery during general anesthesia? / A aplicação tópica de ácido tranexâmico reduz o sangramento intraoperatório em cirurgia sinusal durante anestesia geral?

Abstract Introduction Tranexamic acid is a hemostatic agent, which inhibits fibrin degradation, which may be beneficial in controlling bleeding during surgery. Objectives The purpose of this study was to provide a meta-analysis and review of the effects of tranexamic acid on hemorrhage and surgical fields and side effects on patients during endoscopic sinus surgery. Methods Two authors independently searched six databases (Medline, Scopus, Embase, Web of Science, Google Scholar and Cochrane library) from the start of article collection until July 2018. Postoperative complications such as intraoperative bleeding, operative time, hypotension, nausea, vomiting, and coagulation profile were included in the analysis of tranexamic acid (Treatment Group) and placebo (Control Group) during the operation. Results The amount of blood loss during surgery was statistically lower in the treatment group compared to the placebo group, and the surgical field quality was statistically higher in the treatment group than in the placebo group. On the other hand, there was no significant difference in operation time, hemodynamics, or coagulation profile between groups. In addition, tranexamic acid had no significant effect on vomiting and thrombosis compared to the Control Group. Conclusion This meta-analysis has shown that topical administration of tranexamic acid can reduce the amount of bleeding during surgery and improve the overall quality of the surgery. Hemodynamic instability during surgery, vomiting after surgery, or abnormal clotting profile were not reported. Additional studies are needed to confirm the results of this study because there are fewer studies.

Resumo Introdução O ácido tranexâmico é um agente hemostático, que inibe a degradação da fibrina e pode ser benéfico no controle do sangramento durante a cirurgia. Objetivos Fazer uma metanálise e revisão dos efeitos do ácido tranexâmico na hemorragia e nos campos cirúrgicos e efeitos colaterais em pacientes durante a cirurgia endoscópica do seio nasal. Método Dois autores realizaram independentemente uma busca em seis bancos de dados (Medline, Scopus, Embase, Web of Science, Google Scholar e Cochrane) desde o início da coleta de artigos até julho de 2018. Complicações pós-operatórias como sangramento intraoperatório, tempo operatório, hipotensão, náusea, vômitos e perfil de coagulação foram incluídos na análise do ácido tranexâmico (grupo de tratamento) e placebo (grupo controle) durante a cirurgia. Resultados A quantidade de perda de sangue durante a cirurgia foi estatisticamente menor no grupo de tratamento comparado com o grupo placebo e a qualidade do campo cirúrgico foi estatisticamente maior no grupo de tratamento do que no grupo placebo. Por outro lado, não houve diferença significante no tempo cirúrgico, hemodinâmica ou perfil de coagulação entre os grupos. Além disso, o ácido tranexâmico não teve efeito significante na ocorrência de vômitos e trombose em comparação ao grupo controle. Conclusão Esta metanálise mostrou que a administração tópica de ácido tranexâmico pode reduzir a quantidade de sangramento durante a cirurgia e melhorar a qualidade geral dela. Instabilidade hemodinâmica durante a cirurgia, vômitos após a cirurgia ou perfil de coagulação anormal não foram relatados. Estudos adicionais são necessários para confirmar os resultados desta pesquisa, porque há poucos estudos na literatura.

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.

Effects of turbinoplasty versus outfracture and bipolar cautery on the compensatory inferior turbinate hypertrophy in septoplasty patients / Efeitos da turbinoplastia versus fratura lateral e cauterização bipolar no volume da concha inferior hipertrófica compensatória em pacientes submetidos a septoplastia

Abstract Introduction: The most common cause of septoplasty failure is inferior turbinate hypertrophy that is not treated properly. Several techniques have been described to date: total or partial turbinectomy, submucosal resection (surgical or with a microdebrider), with turbinate outfracture being some of those. Objective: In this study, we compared the pre- and postoperative lower turbinate volumes using computed tomography in patients who had undergone septoplasty and compensatory lower turbinate turbinoplasty with those treated with outfracture and bipolar cauterization. Methods: This retrospective study enrolled 66 patients (37 men, 29 women) who were admitted to our otorhinolaryngology clinic between 2010 and 2017 because of nasal obstruction and who were operated on for nasal septum deviation. The patients who underwent turbinoplasty due to compensatory lower turbinate hypertrophy were the turbinoplasty group; Outfracture and bipolar cauterization were separated as the out fracture group. Compensatory lower turbinate volumes of all patients participating in the study (mean age 34.0 ± 12.4 years, range 17-61 years) were assessed by preoperative and postoperative 2 month coronal and axial plane paranasal computed tomography. Results: The transverse and longitudinal dimensions of the postoperative turbinoplasty group were significantly lower than those of the out-fracture group (p = 0.004). In both groups the lower turbinate volumes were significantly decreased (p = 0.002, p < 0.001 in order). The postoperative volume of the turbinate on the deviated side of the patients was significantly increased: tubinoplasty group (p = 0.033). Conclusion: Both turbinoplasty and outfracture are effective volume-reduction techniques. However, the turbinoplasty method results in more reduction of the lower turbinate volume than outfracture and bipolar cauterization.

Resumo Introdução: A causa mais comum de falha da septoplastia é a hipertrofia das conchas inferiores não tratada adequadamente. Diversas técnicas foram descritas até o momento: turbinectomia total ou parcial, ressecção da submucosa (cirúrgica ou com microdebridador) e a fratura lateral. Objetivo: Neste estudo, comparamos os volumes pré e pós-operatório da concha inferior com hipertrofia compensatória com o uso de tomografia computadorizada entre pacientes submetidos a septoplastia e turbinoplastia ou fratura lateral com cauterização bipolar. Método: Este estudo retrospectivo incluiu 66 pacientes (37 homens e 29 mulheres) internados em nosso serviço de otorrinolaringologia entre 2010 e 2017 por obstrução nasal e submetidos à cirurgia por desvio de septo nasal. Os pacientes submetidos à turbinoplastia devido à hiperplasia compensatória da concha inferior formaram o grupo turbinoplastia; aqueles submetidos à fratura lateral e cauterização bipolar foram separados, formaram o grupo fratura lateral. Os volumes compensatórios da concha inferior de todos os pacientes que participaram do estudo (idade média de 34,0 ± 12,4 anos, faixa de 17 a 61 anos) foram avaliados por tomografia computadorizada dos seios paranasais nos planos axial e coronal no pré-operatório e aos dois meses do pós-operatório. Resultados: As dimensões transversais e longitudinais do grupo turbinoplastia no pós-operatório foram significantemente menores do que as do grupo de fratura lateral (p = 0,004). Em ambos os grupos, os volumes da concha inferior diminuíram significantemente (p = 0,002, p < 0,001, respectivamente). O volume pós-operatório da concha do lado do desvio aumentou significantemente no grupo turbinoplastia (p = 0,033). Conclusão: Tanto a turbinoplastia como a fratura lateral são técnicas efetivas de redução de volume. No entanto, a turbinoplastia causa maior redução do volume da concha inferior do que a fratura lateral com cauterização bipolar.

RESUMEN Introducción: Los pacientes con lesiones cutáneas presentan cambios en su apariencia personal, no solo por la lesión propiamente dicha, sino también por los tratamientos quirúrgicos a que deben someterse. En la región facial estas lesiones son claramente evidentes y poseen mayor importancia estética. Objetivo: Caracterizar un caso de reconstrucción nasal alar tridimensional por exéresis de carcinoma basocelular en paciente geriátrico. Caso clínico: Paciente masculino de 81 años de edad con antecedentes patológicos personales de hipertensión arterial, que refiere presentar lesión nasal de 5 meses de evolución con crecimiento progresivo. Al examen físico facial se detecta alteración del contorno del ala nasal derecha por una lesión con impresión diagnóstica de carcinoma basocelular. Luego del chequeo preoperatorio se decide la exéresis tridimensional de esta, y reconstrucción mediante injerto cartilaginoso de concha auricular y colgajo pediculado nasogeniano. A las cuatro semanas se programa el segundo acto quirúrgico para la desconexión del colgajo pediculado. Conclusiones: El colgajo pediculado de la región nasogeniana combinado con injerto cartilaginoso autólogo constituye una excelente opción terapéutica que permite la reconstrucción nasal tridimensional, en la cual se obtienen buenos efectos estéticos y funcionales, combinados con una alta satisfacción del paciente por los resultados(AU)

ABSTRACT Introduction: Patients with skin lesions have changes in their personal appearance, not only because of the injury itself, but also because of the surgical treatments they must undergo. In the facial region these lesions are clearly evident and have greater aesthetic importance. Objective: Characterize a case of three-dimensional alar nasal reconstruction by exeresis of basal cell carcinoma in a geriatric patient. Clinical case: An 81-year-old male patient with a personal history of hypertension reports the presence of a nasal lesion of 5-month evolution with progressive growth. At facial physical examination an alteration is detected of the contour of the right nasal wing due to a lesion with a diagnostic impression of basal cell carcinoma. After the preoperative check-up, it is decided to perform three-dimensional exeresis and reconstruction by cartilaginous graft of the auricular concha and nasogenian pedicled flap. At four weeks, the second surgical act is scheduled for disconnection of the pedicled flap. Conclusions: The nasogenian pedicled flap combined with an autologous cartilage graft constituted an excellent therapeutic option that allowed three-dimensional nasal reconstruction, obtaining good aesthetic and functional effects, as well as high patient satisfaction with the results obtained(AU)

Uso da técnica em "spaghetti" para tratamento cirúrgico do lentigo maligno / Use of the "spaghetti" technique for surgical treatment of lentigo maligna

O lentigo maligno (LM) é uma forma de melanoma in situ que mais comumente se apresenta como uma mácula de crescimento lentamente progressivo, pigmentada, na face de idosos com pele danificada pelo sol. Esse melanoma in situ tem um risco (30% a 50%) de progressão para lentigo maligno melanoma. A excisão cirúrgica completa da lesão requer margens de pelo menos 10mm, mesmo para lesões in situ. Porém, quando o crescimento de LM ocorre em áreas de implicações estéticas ou funcionais (face, pescoço, solas), a excisão é frequentemente reduzida para preservar estruturas anatômicas importantes e por razões cosméticas. Além disso, as margens periféricas podem ser clinicamente mal definidas e nem sempre pigmentadas, com extensão subestimada e risco de ressecção insuficiente. A "técnica de espaguete", descrita por Gaudy Marqueste, é uma cirurgia estratégica baseada na amostragem de uma faixa de tecido "spaghettilike" para determinar as margens da lesão antes da remoção do tumor. Após a confirmação anatomopatológica de margens livres de neoplasia, a lesão principal central é ressecada, permitindo a reconstrução do defeito no mesmo procedimento, sendo uma alternativa à cirurgia micrográfica de Mohs.(AU)

Lentigo maligna (LM) is a melanoma in situ that commonly presents as a macula with progressive and irregularly pigmented growth, especially in the face of elderly people with sun-damaged skin. This melanoma in situ has a risk (30-50%) of progression to lentigo maligna melanoma. Complete surgical excision of the lesion requires margins of at least 10 mm, even for lesions in situ. However, when the growth of LM occurs in areas of aesthetic or functional implications (face, neck, and soles), the excision is often reduced to preserve important anatomic structures and for cosmetic purposes. Moreover, the peripheral margins may be clinically ill-defined and not always pigmented, and thus, such cases are associated with underestimated extension and risk of insufficient resection. The "spaghetti" technique, described by Gaudy Marqueste, is a strategic surgical approach based on sampling of a range of "spaghetti-like" strips to determine the margins of the lesion prior to removal of the tumor. After the pathological confirmation of neoplasia-free margins, the main central lesion is resected, allowing reconstruction of the defect in the same procedure, as an alternative to Mohs micrographic surgery.

Effect of Pharyngeal Pack on Postoperative Nausea and Throat Pain in Patients Undergoing Rhinoplasty

Objective: To evaluate the effect of pharyngeal pack on postoperative throat pain and nausea in rhinoplasty patients. Material and Methods: Twenty-eight patients were randomly selected and divided into two groups (n=14). The participants were randomly divided into two groups: G1 - the pharyngeal pack was used (Intervention group) and G2: not used (Control group). Both groups were anesthetized by the same protocol. Throat pain was measured by visual analog scale and nausea by presence / absence. Fischer's exact test, ANOVA, Friedman and Wilcoxon test were used. Results: There was no significant difference in mean pain and presence or absence of nausea between the two groups (p>0.05). But there was a significant difference in mean pain and the presence or absence of postoperative nausea with the intervals (p<0.05). Mean pain had a significant difference 2 hours postoperatively with other times, 6 hours postoperatively with 24 and 72 hours postoperatively, and 24 hours postoperatively with 72 hours (p<0.05). There was no significant difference in the presence or absence of postoperative nausea, between 2 hours and 6 hours postoperatively (p>0.05). The presence or absence of postoperative nausea had a significant difference between 2 hours postoperatively with 24 and 72 hours postoperatively and 6 hours postoperatively with 24 and 72 hours postoperatively (p<0.05). There was no significant difference in nausea between 24 hours and 72 hours postoperatively (p>0.05). Conclusion: None of the two groups were significantly superior in terms of reduction of pain and nausea, but because of the possible effectiveness of the pharyngeal pack in preventing aspiration of objects and tissues during the operation, the use of pharyngeal pack is recommended in patients.

Clinical Effect and Safety of Endoscopic Sinus Surgery in Patients over Seventy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Chronic rhinosinusitis (CRS) is common in the elderly. There are increasing evidence that endoscopic sinus surgery (ESS) can be used to manage geriatric patients safely, although there are still concerns about complications after ESS. Therefore, the clinical effect and the safety of ESS in old patients was evaluated in the present study. SUBJECTS AND METHOD: Retrospective observational studies were performed based on medical records of patients over the age of 70 and who underwent ESS for CRS from January 2009 to December 2017. The clinical effect of ESS was assessed by comparing the sino-nasal outcome test (SNOT-22) scores before and 3 months after surgery. The safety of the operation was evaluated by the occurrence of postoperative major surgical (skull base, orbital and hemorrhage) and medical (ventricular fibrillation, ischemic attack, primary cardiac arrest, cerebrovascular accident, pneumonia, other organ failure and death) complications. RESULTS: Seventy three subjects were enrolled in this study. Bilateral disease was observed in 37 cases (50.7%), and CRS with nasal polyp was found in 31 cases (42.5%). Eight patients (11.0%) had revision cases. The majority (93.2%) had at least one comorbid condition and got prescribed related medicine (87.7%). There was a significant decrease in SNOT-22 score after surgery. Furthermore, there were no major surgical or medical complications except two cases with epistaxis. CONCLUSION: CRS in geriatric patients can also be treated effectively and safely by ESS as it is done for younger adults. However, as the incidence of comorbidities is high in elderly subjects, it is important to evaluate the risk factors preoperatively.

Abordaje multidisciplinario del papiloma invertido nasal asociado con mucopiocele frontoetmoidal orbitario: técnica endoscópica y abierta por otorrinolaringología, neurocirugía y oftalmología / Multidisciplinary approach of nasal inverted papilloma associated with frontoethmoidal orbitary mucopiocele: endoscopic and open technique by otorhinolaryngology, neurosurgery and ophthalmology

Introducción: el papiloma invertido nasal es un tumor nasosinusal primario de comportamiento intermedio, con potencial de malignización y capacidad de recidiva en asociación con mucocele. El manejo quirúrgico de ambas patologías se ha descrito de manera independiente. Caso clínico: paciente con diagnóstico de papiloma invertido nasal Krause III y mucopiocele frontoetmoidal orbitario derecho con destrucción de techo de órbita y pared posterior del seno frontal en quien se realizó el manejo multidisciplinario mediante abordaje endoscópico y abierto sin recidiva luego de un año de seguimiento. Discusión: a la luz de la evidencia actual, el tratamiento del papiloma nasal invertido es quirúrgico recomendando abordajes endoscópicos en estadios I, II y III, y técnicas combinadas en estadio IV. En nuestro caso se realizó una resección endoscópica completa del tumor con frontoetmoidoesfenoidotomía + maxilectomía medial y fresado de inserciones óseas. Para el mucocele frontal, el abordaje debe permitir la remoción de la mucosa sinusal y la secuestrectomía ósea. Teniendo en cuenta la localización lateral y el compromiso osteolítico del techo de la órbita y la pared posterior del seno frontal, se optó por un abordaje abierto mediante un colgajo osteoplástico con cranealización de seno frontal. El manejo de las secuelas orbitarias consistió en la reconstrucción del techo de la órbita y dacriocistorrinostomía endoscópica.

Introduction: Nasal inverted papilloma is a primary nasosinusal tumor of intermediate behavior, with potential for malignancy and relapse capacity in association with mucocele. The surgical management of both pathologies has been described independently. Case report: Patient with a diagnosis of Krause III nasal inverted papilloma and right frontoethmoidal orbitary mucopiocele with destruction of the orbital roof and posterior wall of the frontal sinus is performed using a multidisciplinary approach with an endoscopic and open approach without relapse after one year of follow-up. Discussion: The treatment of inverted nasal papilloma is surgical recommending endoscopic approaches in stages I, II and III, and combined techniques in stage IV. In our case, a complete endoscopic resection of the tumor was performed with frontoethmoidosphenoidotomy + medial maxillectomy and milling of osseous insertions. For the frontal mucocele, the approach should allow the removal of the sinus mucous membrane and the bone sequestractomy. Considering the lateral location, the osteolytic involvement of the orbital roof and the posterior frontal sinus wall, we opted for an open approach using an osteoplastic flap with frontal sinus cranialisation. The management of the orbital sequelae consisted of reconstruction of the orbital roof and endoscopic dacryocystorhinostomy.

Concha bullosa gigante: reporte de un caso / Giant concha bullosa: a case report

La concha bullosa es una variante anatómica del cornete medio nasal. Se reporta un caso de una mujer de 21 años con síntomas de obstrucción nasal severa de ambas fosas nasales. Al examen físico se aprecia gran masa que ocupa la fosa nasal izquierda y una severa desviación septal a la derecha. La tomografía computarizada muestra una concha bullosa gigante izquierda, con neumatización del cornete superior izquierdo y una desviación y adelgazamiento septal severos hacia la fosa nasal derecha. Se realiza cirugía endoscópica con resección de la concha bullosa y corrección de la neumatización del cornete superior, antrostomía maxilar derecha y se lleva a cabo septoplastia como reto quirúrgico, por su grado de dificultad y por la posibilidad de causar complicaciones como la perforación septal.

Concha bullosa is an anatomical variant of the middle nasal conchae. This is a clinical report of a case of a 21 year old woman with severe bilateral nasal fossa obstruction symptoms. During the examination, a large mass was occupying the left nasal fossa. There was also a severe deviation to the right. CT scans showed a giant left Concha bullosa, pneumatization of the superior left Concha with septal thinning and deviation towards the right nasal fossa. Endoscopic surgery is performed including resection of the Concha bullosa, correction of the pneumatization of the superior turbinate, and maxillary antrostomy, in addition, septoplasty is performed as a surgical challenge, due to its degree of difficulty and the possibility of causing complications such as septal perforation.

Introdução: A reconstrução nasal é a mais antiga das cirurgias plásticas. A anatomia nasal é complexa e necessita de uma associação de técnicas para a restauração da função e estética nasal adequada. Pereira et al. descreveram uma técnica que possibilita a reconstrução nasal total da cartilagem alar, com o uso de um enxerto da cartilagem auricular, com mínima deformidade auricular secundária à retirada do enxerto. O objetivo deste trabalho é apresentar uma modificação da técnica acima descrita, que possibilita reconstruir mais uma região anatômica do nariz, sem aumentar a morbidade, realizada por Collares et al., e a sua inserção no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre. Métodos: Foi realizado um estudo retrospectivo. Avaliou-se a inserção da modificação da técnica em 10 pacientes que realizaram reconstrução nasal total. Resultados: Após a análise dos 10 casos, utilizando a modificação da técnica inserida no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, encontramos uma melhoria da forma do nariz, a válvula nasal interna com preservação da função e sem sequelas secundárias à retirada do enxerto auricular. Conclusão: Nesta série de casos, a modificação da técnica de Max Pereira resultou em tratamento estético funcional adequado quando implementada no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, sem aumentar a morbidade na área doadora.

Introduction: Nasal reconstruction is the oldest plastic surgery technique. The nasal anatomy is complex and requires an association of techniques for the restoration of function and adequate nasal esthetics. Pereira et al. described a technique that allows total nasal reconstruction of the alar cartilage through the use of an auricular cartilage graft, with minimal deformity secondary to the donor site. The objective of the present study is to present a modification, by Collares et al., of the technique described above, which allows the reconstruction of another anatomical region of the nose without increasing morbidity, and its insertion into the total nasal reconstruction protocol of Hospital de Clínicas of Porto Alegre. Methods: A retrospective study was conducted. We evaluated technique modification in 10 patients who underwent total nasal reconstructions. Results: After examining the 10 patients who were treated with the modified total nasal reconstruction protocol at the Hospital de Clínicas of Porto Alegre, we observed an improvement in the nose shape and internal nasal valve with preservation of function, without sequelae secondary to auricular graft removal. Conclusion: In this case series, the modification of the Max Pereira technique resulted in adequate aestheticfunctional treatment when implemented in the total nasal reconstruction protocol of the Hospital de Clínicas of Porto Alegre, without increasing the morbidity in the donor area.
