A Systematic Literature Study of the Sinus Septi Nasi, Crista Galli and Other Minor Pneumatizations / Estudio Bibliográfico Sistemático del Seno Septi Nasi, Crista Galli y Otras Neumatizaciones Menores

SUMMARY: Variations in the paranasal sinuses and pneumatizations originating from these structures are clinically important for surgical procedures to be performed in the nose and nasal cavity regions. No systematic review examining the sinus septi nasi, crista galli and other minor pneumatizations was found in the literature review. This study aimed to review the papers in the literature including the sinus septi nasi, crista galli and other minor pneumatizations and standardize the mean incidence, distribution by sex, age and origin of these structures. Furthermore, it was aimed to examine the height, length, and width values of sinus septi nasi and crista galli pneumatizations, determine the measurement intervals and measurement values, and standardize them. The studies involving these pneumatizations were reviewed from various databases. After being evaluated according to the inclusion and exclusion criteria, 35 articles between the years 1991-2021 were reviewed. Based on the data obtained from these articles, we examined the incidence of sinus septi nasi, crista galli, and other minor pneumatizations. Middle nasal turbinate pneumatization had the highest incidence among all these pneumatizations. Uncinate process pneumatization had the lowest incidence. Considering the distribution by sex, no difference was found. Upon examining the age range, there were people aged between 1-95 years, and the mean age range was 33.05-41.48. The length, width and height values of crista galli and sinus septi nasi could not be standardized due to the insufficient number of studies and variable data in the literature. We believe that our study will contribute to similar future studies in larger populations with the clinical procedures to be performed in and around the nasal cavity.

Las variaciones en los senos paranasales y las neumatizaciones que se originan en estas estructuras son clínicamente importantes para los procedimientos quirúrgicos que se realizan en las regiones de la nariz y la cavidad nasal. En la revisión de la literatura no se encontró ninguna revisión sistemática que examinara el seno septi nasi, la crista galli y otras neumatizaciones menores. Este estudio tuvo como objetivo revisar los trabajos en la literatura que incluyen el seno septi nasi, la crista galli y otras neumatizaciones menores y estandarizar la incidencia media, la distribución por sexo, edad y origen de estas estructuras. Además, tuvo como objetivo examinar los valores de altura, longitud y ancho de las neumatizaciones del seno septi nasi y crista galli, determinar los intervalos de medición y los valores de medición, y estandarizarlos. Los estudios relacionados con estas neumatizaciones se revisaron a partir de varias bases de datos. Luego de ser evaluados según los criterios de inclusión y exclusión, se revisaron 35 artículos entre los años 1991-2021. Sobre la base de los datos obtenidos de estos artículos, examinamos la incidencia de septi nasi nasi, crista galli y otras neumatizaciones menores. La neumatización de la concha nasal media tuvo la mayor incidencia entre todas estas neumatizaciones. La neumatización del proceso uncinado tuvo la menor incidencia. Considerando la distribución por sexo, no se encontró diferencia. Al examinar el rango de edad, había personas con edades entre 1 y 95 años, y el rango de edad promedio fue de 33,05 a 41,48. Los valores de longitud, ancho y altura de crista galli y seno septi nasi no pudieron estandarizarse debido a la cantidad insuficiente de estudios y datos variables en la literatura. Creemos que nuestro estudio contribuirá a futuras investigaciones similares en poblaciones más grandes con los procedimientos clínicos que se realizarán en y alrededor de la cavidad nasal.

Asociación entre las variantes anatómicas del complejo osteomeatal y patología inflamatoria sinusal: estudio de casos y controles / Association between anatomical variants of the osteomeatal complex and inflammatory sinus pathology: case-control study

Introducción: las variantes anatómicas nasosinusales pueden ser una causa frecuente de infecciones crónicas, y resulta importante identificarlas en la práctica diaria. Objetivo: determinar la asociación entre las variantes anatómicas del complejo osteomeatal (COM) y el desarrollo de patologías inflamatorias nasosinusales. Materiales y métodos: estudio de casos y controles, muestra de 226 pacientes identificando las variantes anatómicas del COM en la tomografía computada (TAC) de senos paranasales (SPN) y su correlación clínica. Resultados: el 51,9 % presentaron hallazgos imagenológicos indicativos de patología inflamatoria nasosinusal y el 19,8 % reportaron sintomatología sugestiva de sinusitis en la historia clínica. Los SPN más afectados fueron: maxilares (46,9 %) y etmoidales (23 %). Las variantes anatómicas más frecuentes fueron las celdillas de Agger Nasi (50,2 %) y la desviación septal (46,2 %). Se encontró como variable estadísticamente significativa la inserción lateral de la apófisis unciforme (p = 0,015) más frecuente del lado izquierdo (p = 0.018, odds ratio [OR] = 4,078, intervalo de confianza [IC] 95 % = 1,3-12,6). Discusión: Se confirmó la incidencia de las variantes anatómicas más frecuentes en la literatura, sin embargo, no se correlacionan con los hallazgos clínicos para la serie de pacientes estudiada en comparación con otros estudios. Existe una alta relación entre la inserción lateral de apófisis unciforme y hallazgos de rinosinusitis escasamente documentados en la literatura médica. Conclusión: se requieren más estudios sobre modelos predictivos en muestras poblacionales mayores y protocolos de lectura TAC enfocados sobre diferentes variantes anatómicas de la apófisis unciforme.

Introduction: Sinonasal anatomical variants can be a frequent cause of chronic in- fections, so it is important to identify them in daily practice. Objective: To determine the association between the anatomical variants of the osteomeatal complex (OCM) and the development of sinonasal inflammatory pathologies. Materials and methods: Case-control study, a sample of 226 patients is analyzed identifying the anatomical variants of OCM in computed tomography of the paranasal sinuses and their clinical correlation. Results: 51.9% presented imaging findings indicative of sinonasal in- flammatory disease, 19.8% reported symptoms suggestive of sinusitis in the clinical history. The most affected paranasal sinuses were: maxillary (46.9%) and ethmoid (23%). The most frequent anatomical variants were Agger Nasi cells (50.2%) and septal deviation (46.2%). The lateral insertion of the uncinate process (p=0.015) was a statistically significant variable, more frequent on the left side (p=0.018, odds ratio [OR]=4.078, 95% confidence interval [CI]=1.3-12.6). Discussion: The incidence of the most frequent anatomical variants in the literature was confirmed, however not correlated with the clinical findings for the series of patients studied in comparison with other studies. There is a high relationship between the lateral insertion of the uncinate process and rhinosinusitis findings that are scarcely documented in the medical literature. Conclusion: More studies are required on predictive models in larger population samples and tomographic reading protocols focused on different anatomical variants of the uncinate process

Strategy of the diagnosis and treatment for epistaxis and guideline for clinical application of MasterPillar / 临床耳鼻咽喉头颈外科杂志

Epistaxis is a common otorhinolaryngological emergency with complex etiological factors and varied clinical manifestations. The key to epistaxis treatment is accurate diagnosis and adequate hemostasis. Electrocoagulation is a reliable, safe and effective treatment for epistaxis. However, there are still several deficiencies in application of the commonly used electrocoagulation surgical products. This paper introduces a new type of radiofrequency head incorporating the dynamic circulatory functions of drip, irrigation, hemostasis and aspiration. We aim to achieve noninvasive, effective and accurate hemostasis in the treatment of epistaxis or nasal sinus surgery.

Clinical characteristics of nasal respiratory epithelial adenomatoid hamartoma / 临床耳鼻咽喉头颈外科杂志

〓 Objectives: To analyze the pathological and clinical features of nasal respiratory epithelial adenomatoid hamartoma（REAH）, and summarize the diagnostic points, to improve the experience of diagnosis and treatment. Methods:The clinical data of 16 patients with REAH were analyzed retrospectively. The clinical manifestations, pathological features, imaging features, surgical treatment and prognosis were summarized. Results:16 cases of REAH were studied, 10 cases（62.50%） were associated with sinusitis, 1 case（6.25%） was associated with inverted papilloma, 1 case（6.25%） was associated with hemangioma. 5 cases（31.25%） had a history of nasal sinus surgery, including 1 case with 3 times of nasal sinus surgery, 1 case with 2 times of nasal sinus surgery, 3 cases with 1 time of nasal sinus surgery; 10 cases（62.50%） occurred in the bilateral olfactory cleft, 2 cases（12.50%） in the unilateral olfactory cleft, 3 cases（18.75%） in the unilateral middle turbinate, 1 case（6.25%） in the nasopharynx. All 16 patients were pathologically diagnosed as REAH. In the patients with lesions located in bilateral olfactory fissures, symmetrical widening of olfactory fissures and lateral displacement of middle turbinate were observed on preoperative sinus CT. The average width of bilateral olfactory fissures was （9.9±2.70） mm. The ratio of wide to narrow olfactory cleft was 1.21 ± 0.19. There was no significant difference in Lund-Mackay score between the two sides（P>0.05）. All patients underwent surgery under general anesthesia and nasal endoscopy. The follow-up period ranged from 1 to 66 months, and no recurrence occurred. Conclusion:Preoperative diagnosis of REAH is facilitated by the combination of clinical manifestations and endoscopic and imaging features. Endoscopic complete resection can achieve a good therapeutic effect.

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.

Desarrollo de una app móvil para la evaluación preoperatoria de la tomografía de senos paranasales: un paso hacia la inteligencia artificial / Development of a Movil App for the Preoperative Evaluation of Sinus CT Scan: One Step Towards Artificial Intelligence

Introducción: la revolución tecnológica que hemos vivido en los últimos años ha generado un extendido uso de la inteligencia artificial (IA) como tecnología de base para el desarrollo de diversos sistemas y soluciones en medicina. En el campo de la otorrinolaringología, estamos viendo hasta ahora los primeros esfuerzos para aprovechar este surgimiento. Objetivo: el presente proyecto busca describir el proceso de desarrollo de una app móvil creada gracias al trabajo colaborativo entre otorrinolaringólogos e ingenieros biomédicos, que tiene la intención de optimizar la evaluación preoperatoria de la tomografía de senos paranasales (TC de SPN). Métodos: el desarrollo de la app siguió el método de priorización para especificaciones de MoSCoW. Utilizamos la información recolectada de encuestas realizadas a 29 expertos en rinología de diferentes partes del mundo, quienes evaluaron variantes anatómicas en la tomografía y se utilizaron dos modelos de regresión para la predicción de dificultad y riesgo a partir de herramientas de aprendizaje estadístico. Conclusión: hemos desarrollado una herramienta y un modelo estadístico que es fácil de utilizar y que idealmente ayudará al cirujano en el proceso de evaluación preoperatoria de TC de SPN. Este es un ejercicio que permite demostrar la eficacia de un desarrollo colaborativo para lograr soluciones en nuestra especialidad y un acercamiento hacia la IA.

Introduction: The recent technology revolution that we have experienced has generated extensive interest in the use of artificial intelligence (AI) in the development of various systems and solutions in medicine. In the field of Otorhinolaryngology, we are seeing the first efforts to take advantage of this flourishing area. Objective: We sought to describe the development process of a mobile app created through a collaborative effort between ENT surgeons and biomedical engineers. This app has the intention to optimize the preoperative evaluation of paranasal sinus tomography (CT) to improve safety and outcomes in Endoscopic Sinus Surgery (ESS). Methods: The development of the app followed the prioritization method for MoSCoW specifications. We used the information collected from surveys of 29 Rhinology experts from different parts of the world, who evaluated anatomical variants on sinus CT scans. Two regression models were used to predict difficulty and risk using statistical learning. Conclusion: Via statistical modelling, we have developed a user-friendly tool that will ideally help surgeons assess the risk and difficulty of ESS based on the pre-operative CT scan of the sinuses. This is an exercise that demonstrates the efficacy of the collaborative efforts between surgeons and engineers to leverage AI tools and promote better solutions for our patients.

Rabdomiosarcoma del ala nasal en un paciente pediátrico. Un reporte de caso / Nasal ala Alveolar Rhabdomyosarcoma in a pediatric patient. A rare case report

Dada la respiración nasal preferencial que tiene la población pediátrica en los primeros meses de vida, la obstrucción nasal tiene más repercusiones a nivel clínico a diferencia de un adulto, lo cual hace más prioritario su diagnóstico y manejo. Una de las principales causas de obstrucción nasal en niños son las masas nasales, las cuales debido a sus múltiples etiologías causan bastante incertidumbre diagnóstica en el equipo médico. En este artículo se presenta el caso de una paciente de 10 meses con una masa en el ala nasal de crecimiento rápido; se realiza un rápido diagnóstico de rabdomiosarcoma que requiere un adecuado manejo. El rabdomiosarcoma con patrón alveolar se presenta de forma inusual en esta ubicación, es por esto por lo que se considera importante presentar este caso para mantenerlo en el algoritmo diagnóstico como una posibilidad y que, así como en el caso presentado, se pueda tener un diagnóstico temprano, un tratamiento adecuado y un resultado estético y funcional favorable.

Given preferential nasal breathing in the first months of life in the pediatric population, nasal obstruction has more clinical repercussions than it would have in adults, hence the need to give higher priority to its diagnosis and management. One of the main causes of nasal obstruction in children is the presence of nasal masses, which cause considerable diagnostic uncertainty in the medical team, because of their multiple etiologies. In this article, the case of a 10-month-old patient with a rapidly growing mass in the nasal ala is presented. A rhabdomyosarcoma was promptly diagnosed and adequately managed. Rhabdomyosarcoma with an alveolar pattern occurs in an unusual way in this location; for this reason, this case is important in order to include this possibility in the diagnostic algorithm and, as was the case in this patient, reach an early diagnosis and institute adequate treatment resulting in favorable aesthetic and functional results.

Complicaciones intraoperatorias en cirugía endoscópica nasosinusal en Servicio de Otorrinolaringología del Hospital del Salvador, revisión en los últimos 10 años / Intraoperative complications in endoscopic sinus surgery in otorhinolaryngology service at Hospital del Salvador, review in the last 10 years

Introducción: La cirugía endoscópica nasal (CEN) corresponde a una técnica quirúrgica mínimamente invasiva. Ha disminuido la morbimortalidad secundaria al acto quirúrgico. Pese a esto, no está exenta de riesgos y sus complicaciones pueden variar en severidad desde leves hasta catastróficas, siendo la hemorragia nasal la más frecuente. Objetivo: Analizar las complicaciones intraoperatorias, factores asociados a complicaciones y manejo en nuestra realidad local. Material y Método: Estudio retrospectivo, revisión de protocolos operatorios de pacientes atendidos en el Hospital del Salvador entre los años 2009 y 2019. Resultados: Se revisaron 602 cirugías de las cuales se excluyeron 18. De un total de 584 CEN realizadas durante los últimos diez años, la incidencia de complicaciones intraoperatorias fue de 3,3%. Sólo se observaron complicaciones hemorrágicas (2%) y orbitarias (1,2%). La incidencia de complicaciones mayores fue 0,51%. La única variable asociada de forma significativa con la presencia de complicación intraoperatoria fue el tiempo quirúrgico. Conclusión: Como centro presentamos una tasa de complicaciones intraoperatorias de CEN baja en los últimos diez años, dentro de las cuales las más frecuentes son las hemorrágicas y las orbitarias; comparables con la literatura internacional. Se establece el primer reporte a nivel nacional sobre las complicaciones intraoperatorias de CEN.

Introduction: Endoscopic sinus surgery (ESS) is a minimally invasive surgical technique. It has decreased morbidity and mortality secondary to the surgical act. Despite this, endoscopic sinus surgery is not a risk-free procedure and its complications can range from mild to severe, with nosebleed being the most frequent. Aim: To analyze the surgical results of nasal endoscopic surgery, with its intraoperative complications and management in our local reality. Material and Method: Retrospective study, review of operative protocols of patients attended at the Salvador Hospital between 2009 and 2019. Results: 602 surgeries were reviewed, of which 18 were excluded. Of a total of 584 ESS performed during the last ten years, the incidence of intraoperative complications was 3,3%. Only hemorrhagic (2%) and orbital complications (1,2%) were observed. The incidence of major complications was 0,51%. The only variable significantly associated with the presence of intraoperative complications was surgical time. Conclusion: As a center, we present a low rate of intraoperative complications of ESS in the last ten years, among which the most frequent are hemorrhagic and orbital; comparable to international literature. The first national report on intraoperative complications of ESS is established.

Eficácia e segurança do dupilumabe no tratamento da rinossinusite crônica com polipose nasal / Efficacy and safety of dupilumab in the treatment of chronic rhinosinusitis with nasal polyposis

A rinossinusite crônica (RSC) é uma síndrome caracterizada pela inflamação da mucosa nasal e dos seios paranasais por pelo menos 12 semanas, acometendo de 5% a 12% da população geral. A síndrome é associada a alta morbidade e considerada um grande problema de saúde pública devido a sua prevalência, seu custo para a sociedade e ao impacto que acarreta na qualidade de vida dos pacientes e em seu desempenho escolar ou profissional. Ademais, a RSC está associada a diversas comorbidades, como dermatite atópica, distúrbios respiratórios do sono, conjuntivite, otite média, asma e problemas emocionais. O dupilumabe é eficaz e seguro no tratamento da RSC com polipose nasal. A eficácia é progressiva no primeiro ano de tratamento, e a posologia de 300 mg a cada duas semanas é superior em relação à de cada quatro semanas. A interrupção do tratamento com 24 semanas acarreta a perda parcial de seus efeitos benéficos. O imunobiológico também é eficaz no controle da asma nos pacientes que apresentam essa doença como comorbidade. Alguns pacientes podem apesentar aumento transitório de eosinófilos sanguíneos, e 2,7% desenvolveram conjuntivite como reação adversa nos estudos SINUS-24 e SINUS-52. O dupilumabe é uma excelente opção terapêutica no tratamento concomitante de múltiplas doenças caracterizadas pela inflamação de tipo II.

Chronic rhinosinusitis (CRS) is a syndrome characterized by inflammation of the nasal mucosa and paranasal sinuses for at least 12 weeks, affecting 5% to 12% of the general population. The syndrome is associated with high morbidity and is considered a major public health problem because of its prevalence, its cost to society, and the impact it has on patients' quality of life and on their school or professional performance. Furthermore, CRS is associated with several comorbidities, such as atopic dermatitis, sleep-disordered breathing, conjunctivitis, otitis media, asthma, and emotional problems. Dupilumab is effective and safe in the treatment of CRS with nasal polyposis. Effectiveness is progressive in the first year of treatment, and a dosage of 300 mg every two weeks is more effective than that of every four weeks. Discontinuing treatment at 24 weeks results in partial loss of its beneficial effects. The biological drug is also effective in controlling asthma in patients who have this disease as a comorbidity. Some patients may experience a transient increase in blood eosinophils, and 2.7% developed conjunctivitis as an adverse reaction in the SINUS-24 and SINUS-52 studies. Dupilumab is an excellent therapeutic option in the concomitant treatment of multiple diseases characterized by type II inflammation.

Hemangioma fusocelular en las fosas nasales y los senos etmoidales en un lactante de 4 meses de edad / Spindle cell hemangioma of nasal passage and ethmoidal sinus in a 4-month old infant

El hemangioma fusocelular es una neoplasia vascular benigna infrecuente. Afecta la dermis y la hipodermis de la parte distal de las extremidades; la afectación de la cabeza y el cuello es muy poco frecuente y nunca se informó compromiso de los senos paranasales. Este es el caso de un lactante de 4 meses con obstrucción nasal desde las 2 semanas debido a un tumor en los senos etmoidales que obstruía las fosas nasales. Se diagnosticó hemangioma fusocelular y se extirpó parcialmente el tumor. A los seis meses de seguimiento, se observó una regresión mínima con lesiones residuales. A los 30 meses, se observó que el tumor residual había desaparecido. El hemangioma fusocelular es infrecuente en cabeza y cuello y, a veces, la presentación no es indicativa del diagnóstico. El examen histopatológico ayuda con el diagnóstico diferencial y el tratamiento. La sensibilización sobre el hemangioma fusocelular podría aumentar los casos informados.

Spindle cell hemangioma (SCH) is a benign unusual vascular neoplasm. It does not have gender predilection and can occur at all ages. The disease affects dermis and subcutis of distal extremities predominantly; head and neck involvement is very rare, paranasal sinus involvement has not been reported before. Herein we present a 4-month-old infant with nasal obstruction since two weeks of age due to a mass in ethmoid sinus obliterating the nasal passage. After the histopathological diagnosis of SCH, the tumor was partially resected. In the sixth month follow-up, there was minimal regression of residual lesions. In the imaging studies performed 30 months after the surgery, the residual mass was found to be disappeared. SCH is not frequent in the head and neck, and presentation of some patients may not suggest the diagnosis. Histopathology is important for differential diagnosis and to orientate treatment. Awareness of SCH may increase the reported cases

Studies on efficacy of a bioabsorbable steroid-eluting sinus stent in the frontal sinus opening of chronic rhinosinusitis with nasal polyps / 中华耳鼻咽喉头颈外科杂志

Objective: To assess the efficacy of a bioabsorbable steroid-eluting sinus stent in improving surgical outcomes when placed in the frontal sinus ostium (FSO) following full endoscopic sinus surgery (ESS) in patients with whole group chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: Patients with whole group CRSwNP who had similar lesions on bilateral sinus between September 2019 and March 2020 in Department of Otorhinolaryngology Head and Neck Surgery, Shanghai Changhai Hospital were chosen. Patients with CRSwNP who underwent extended ESS were randomly assigned to receive a steroid-eluting sinus stent in one FSO whereas the contralateral side received surgery alone. Endoscopic evaluations recorded at 30, 90 days postoperative were graded by an independent assessment panel to assess the need for interventions in the FSO. Semi-quantitative data with CT and endoscopic score were performed by rank sum test. The need for postoperative intervention and the patency rate of FSO were analyzed using the McNemar test. Results: Thirty-one patients with whole group CRSwNP met all eligible criteria, including 17 males and 14 females, with the age of (44.5±11.8) years(x¯±s). Stents were successfully placed in one FSO of all patients. At 30 days post-ESS, the assessment panel reported that steroid-eluting stents reduced the need for postoperative interventions by 41.0% (χ2=5.314,P=0.021), the need for oral steroid interventions by 40.0% (χ2=4.133,P=0.042) and the need for surgical interventions by 74.8% (χ2=4.292,P=0.038) compared to control sinuses with no stents. Clinical surgeons also reported greater diameter of FSO compared to control sinuses at 30 days post-ESS (74.2% vs 48.4%, χ2=4.351, P=0.037). These results at 90 days post-ESS were consistent with those at 30 days post-ESS. Conclusion: Bioabsorbable steroid-eluting sinus stents in the FSO can reduce polyp formation, adhesion, and the need for postoperative interventions in FSO of CRSwNP patients and improve the early postoperative outcomes.

Granulomatosis with polyangiitis with nasal symptoms as the first clinical manifestation: clinical analysis of 18 cases / 中华耳鼻咽喉头颈外科杂志

Objective: To analyze and summarize the diagnosis, treatment and prognosis of granulomatosis with polyangiitis (GPA) with nasal symptoms as the first clinical manifestation. Methods: The data of 18 patients of GPA with nasal mucosal symptoms as the first clinical manifestation from the Department of Otorhinolaryngology Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University between 2005 and 2019 was collected, including 8 males and 10 females, aged from 5 to 68 years. Nasal endoscopy, imaging examination, laboratory examination, immunological and histopathological examination of nasal mucosa were completed. All patients were treated with glucocorticoid combined with cyclophosphamide and were followed up for 2 to 15 years. Descriptive statistical method was used for analysis. Results: All the 18 patients had the nasal mucosal symptoms as the first clinical manifestation, including nasal obstruction, running nose and epistaxis. Nasal endoscopy showed swelling, erosion, scab and bleeding of nasal mucosa, and 6 cases had nasal septal perforation. Nasal sinus CT scan showed high density shadow of sinus, as well as hyperostosis and osteosclerosis. CT imaging features of pulmonary showed nodular lesion or patchy infiltration in 12 patients and cavitation was found in 6 cases. Laboratory results showed that 13 cases were positive for anti-neutrophil cytoplasmic antibodies (ANCA), and 5 cases were negative. During follow-up period, thirteen patients were symptomatic controlled and survived; two patients died of disease progression; one patient gave up treatment and died; two patients were lost to follow-up. Conclusions: Nasal symptoms are the first clinical manifestation of GPA. Early diagnosis and early treatment with glucocorticoid combined with cyclophosphamide can effectively improve the survival rate.

Epistaxis: the cause found beyond the nose

Renal cell carcinoma (RCC) is a malignant disease that is often diagnosed at a metastatic stage. The head and neck represent up to 3% of the metastatic RCC, and the paranasal sinus area is one of the least involved sites. Here, we introduce the case of a 74-year-old female patient who presented with a history of traumatic nasal bleed. A cranial computed tomography scan and magnetic resonance imaging showed a fronto-ethmoidal mass with pachymeningeal involvement. A nasal biopsy from the paranasal sinuses was taken. On histopathological examination, metastatic clear cell carcinoma was the main hypothesis, which later was confirmed to be RCC on immunohistochemistry. On further radiological examination, an exophytic mass was depicted in the kidney's upper and middle pole. The patient had no renal complaints and was asymptomatic. Fronto-ethmoidal sinus is a rare site for metastatic RCC, especially in cases where the patient is asymptomatic. Early detection by keeping RCC metastasis as the differential diagnosis in such cases can lead to early treatment and improve the overall survival of the patient.

Predominant endotype of nasal polyps in a sample of Filipinos following endoscopic sinus surgery for chronic rhinosinusitis with nasal polyposis

Objective@#To determine the prevalence of eosinophilic and non-eosinophilic nasal polyps in Filipino patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) who underwent endoscopic sinus surgery. @*Methods@#Design: Retrospective Chart Review. Setting: Tertiary Government Training Hospital. Participants: A consecutive sample of adult patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with nasal polyposis at the Rizal Medical Center from 2015-2019.@*Results@#Out of 66 patients who underwent endoscopic sinus surgery during the study period, 36 (54.55%) had an eosinophilic endotype while 30 (45.45%) had a non-eosinophilic endotype. @*Conclusion@#The slight predominance of eosinophilic nasal polyps found in our sample may suggest a contrasting trend compared to our Asian neighbors, who have a predominantly non[1]eosinophilic endotype – Indonesia (90.47%), Thailand (81.9%), South Korea (66.7%) and China (53.6%). However, this predominance is still lower than the 78-88% eosinophilia reported among Caucasians. Larger series may confirm these preliminary findings

Mucormicosis rino-órbito-cerebral crónica: una patología poco frecuente / Chronic rhino-orbital-cerebral mucormycosis: an uncommon pathology

Resumen La mucormicosis rino-órbito-cerebral (ROC) crónica es una patología poco frecuente, con un número reducido de casos publicados en la literatura, cuyas manifestaciones son muy diversas e inespecíficas. El tratamiento se basa en la experiencia de casos y series de casos. Las herramientas terapéuticas incluyen el uso de antifúngicos endovenosos y orales por tiempo prolongado, asociado o no a debridamiento quirúrgico amplio, pudiendo requerir incluso exenteración orbitaria. Presentamos a continuación un caso de mucormicosis ROC crónica, junto con las dificultades para su diagnóstico y manejo, en el que destaca el enfrentamiento multidisciplinario. Dada la poca frecuencia de esta enfermedad, nos parece relevante difundirlo.

Abstract Chronic rhino-orbital-cerebral mucormycosis is a rare condition with a small number of cases that have been published, whose manifestations are very diverse and nonspecific. The treatment is based on case series experiences. Therapeutic options include the use of long-term intravenous and oral antifungals, associated or not with extensive surgical debridement, and may even require orbital exenteration. We present below a case of chronic rhino-orbital-cerebral mucormycosis with the challenge of diagnosis and management in which multidisciplinary work is fundamental. Since it is an uncommon pathology, it seems relevant to share the information.

Sinonasal neoplasms in 49 dogs: clinical, macroscopic, and histopathological aspects / Neoplasmas nasossinusais em 49 cães: aspectos clínicos, macroscópicos e histopatológicos

This study aimed to quantify nasosinusal neoplasms diagnosed in dogs in 20 years (2000-2019) and characterize the main clinical, macroscopic, and histological aspects of these neoplasms. The sex, breed, age, skull conformation, the main clinical signs, and the anatomopathological characteristics (distribution, macroscopy, and histology) were computed. During this period, 49 dogs were affected by neoplasms in these regions, totaling 50 neoplasms (one dog had two neoplasms of different locations and histogenetic origins). Similar amounts of mixed-breed dogs (25/49) and purebred dogs (24/49) were affected, these distributed in 16 breeds. Among purebreds, it was noted that dogs with mesocephalic cranial conformation (12/24) were the most affected, followed by dolichocephalic (10/24) and brachycephalic (2/24). There were 22 cases in males and 27 in females, making a proportion of 1:1.23. There was an age variation from 11 months to 16 years old. The epithelial neoplasms have occurred in older dogs compared to those of other histogenic origins (mesenchymal and other origins/round cells). The main clinical signs were similar between the histogenetic categories, related to the involvement of the upper respiratory tract, sometimes accompanied by nervous signs (when there was brain invasion of nasal neoplasms or vice versa). The possible origin site was mostly in the nasal cavity concerning the paranasal sinuses (and other locations). Invasions occurred in different tissues adjacent to the nasal cavity and paranasal sinuses, resulting in cranial and facial deformities (21/49). The frequency was 48% of epithelial neoplasms, 32% of mesenchymal neoplasms, and 10% of neoplasms with other origins and round cells. The neoplasms most frequently observed, in decreasing order of frequency, were: adenocarcinoma (9/50), squamous cell carcinoma (9/50), transmissible venereal tumor (5/50), osteosarcoma (5/50), chondrosarcoma (4/50), and undifferentiated sarcoma (4/50). Through this study, it was possible to establish the frequency of these neoplasms in 20 years and their clinical, macroscopic, and histological characteristics.(AU)

Este estudo teve como objetivo quantificar os neoplasmas nasossinusais diagnosticados em cães em 20 anos (2000-2019) e caracterizar os principais aspectos clínicos, macroscópicos e histológicos desses neoplasmas. Foram computados sexo, raça, idade, conformação do crânio, principais sinais clínicos e características anatomopatológicas (distribuição, macroscopia e histologia). Nesse período, 49 cães foram acometidos por neoplasmas nessas regiões, totalizando 50 neoplasmas (um cão tinha dois neoplasmas de localização e origens histogenéticas distintas). Foram acometidas quantidades semelhantes de cães sem raça definida (25/49) e de cães com raça definida (24/49), estes distribuídos em 16 raças. Entre os cães com raça definida, notou-se que os cães com conformação craniana mesocefálica (12/24) foram os mais acometidos, seguidos pelos dolicocefálicos (10/24) e braquicefálicos (2/24). Foram observados 22 casos em machos e 27 em fêmeas, perfazendo a relação de 1:1,23. Ocorreu uma variação de idade de 11 meses a 16 anos; tendo os neoplasmas epiteliais ocorrido em cães mais velhos quando comparado aos de outras origens histogênicas (mesenquimais e outras origens/células redondas). Os principais sinais clínicos foram semelhantes entre as categorias histogenéticas, sendo relacionados ao comprometimento do trato respiratório superior, por vezes acompanhados de sinais nervosos (quando houve invasão encefálica de neoplasmas nasais ou vice-versa). O possível local de origem em sua maioria foi na cavidade nasal em relação aos seios nasais (e de outras localizações). Ocorreram invasões para diferentes tecidos adjacentes à cavidade nasal e seios paranasais, tendo como consequência deformidades cranianas e faciais (21/49). A frequência foi de 48% de neoplasmas epiteliais, 32% de neoplasmas mesenquimais e 10% de neoplasmas com outras origens e de células redondas. Os neoplasmas mais frequentemente observados, em ordem decrescente de frequência, foram: adenocarcinoma (9/50), carcinoma de células escamosas (9/50), tumor venéreo transmissível (5/50), osteossarcoma (5/50), condrossarcoma (4/50) e sarcoma indiferenciado (4/50). Com isso, pode-se estabelecer a frequência desses neoplasmas em 20 anos, bem como suas características clínicas, macroscópicas e histológicas.(AU)
