Sinonasal mucormycosis during 2 years of COVID-19 pandemic in central Iran: incidence rate and clinical features / Mucormicosis sinonasal durante 2 años de pandemia de COVID-19 en el centro de Irán: tasa de incidencia y características clínicas

Introduction As a novel infectious disease, COVID-19 is caused by SARS-COV-2, spreading rapidly worldwide. ENT specialists have faced this challenging disease in various ways since the emergence of the COVID-19 pandemic. We are currently facing an increase in cases referred due to sinonasal mucormycosis which is a rare but invasive, rapidly progressive, and life-threatening infection. We provide an overview of this disease's incidence rate and clinical features. Methods This descriptive cross-sectional study was conducted on 46 sinonasal mucormycosis patients who were histopathologically confirmed after sinonasal endoscopic surgery in our educational therapeutic hospital during 2 years of the COVID-19 pandemic from March 20, 2020, to March 20, 2022. Results There was an increase in the incidence of mucormycosis more than twice as much as before. All patients had a history of COVID-19 and 69.6% were diabetic. The median time to symptom onset from COVID-19 detection was 3.3 weeks. A total of 60.9% received steroids while 85.7% were prescribed during COVID-19 treatment. The most common manifestation was orbital involvement (80.4%). Of the 46 study cases, unfortunately, 17 (37%) died. An exciting point in our study was the incidence of peripheral facial palsy which is associated involvement of multiple other cranial nerves (II, III, IV, V, VI) considered to be the likely occurrence of a rare phenomenon called Garcin's syndrome. Conclusion Based on the results of this study, during 2 years of the COVID -19 pandemic, there was an increase in the incidence of sinonasal mucormycosis more than twice as much as before. (AU)

Introducción La enfermedad infecciosa COVID-19, causada por el SARS.COV-2 se ha extendido rápidamente por el mundo. Como otorrinolaringólogos, nos hemos enfrentado a esta enfermedad de diversas maneras durante el periodo de pandemia. Actualmente evidenciamos a un aumento de casos de mucormicosis nasosinusal, infección rara pero invasiva, rápidamente progresiva y amenazante para la vida. Presentamos una descripción general de la incidencia de esta enfermedad, así como sus características clínicas. Métodos Estudio descriptivo transversal de 46 pacientes con mucormicosis nasosinusal confirmados histopatológicamente en un hospital universitario de Irán desde el 20 marzo de 2020 hasta el 20 de marzo de 2022. Resultados El aumento en la incidencia de mucormicosis ha sido más del doble en comparación con el pasado. Los pacientes todos tenían antecedentes de COVID-19, y el 69.6 % de ellos eran diabéticos. El plazo promedio de aparición de los síntomas ha sido 3.3 semanas desde la detección del COVID-19. Un total de 60.9% de pacientes recibieron esteroides mientras que el 85.7% fueron recetados durante el tratamiento contra el COVID-19. La manifestación más frecuente fue la afectación orbitaria (80.4%). De los 46 casos de estudio, lamentablemente, 17 (37%) fallecieron. Un punto emocionante en nuestro estudio fue la incidencia de parálisis facial periférica que está afectada y asociada con la participación de muchos otros nervios craneales (II, III, IV, V, VI) que se considera que es la probable ocurrencia de un fenómeno raro llamado síndrome de Garcin. Conclusión En base a los resultados de este estudio podemos concluir que la incidencia de mucormicosis nasosinusal se duplicó en Irán durante el periodo de pandemia. (AU)

Hematoma orbitario secundario a cirugía endoscópica nasosinusal / Orbital hematoma secondary to endoscopic sinus surgery

Resumen Durante la cirugía endoscópica nasosinusal, la sección inadvertida y retracción hacia la órbita de la arteria etmoidal anterior (AEA) es el mecanismo habitual del hematoma orbitario (HO); éste se manifiesta con proptosis, dolor y déficit visual potencialmente irreversible. El déficit visual es secundario a isquemia del nervio óptico por aumento de la presión intraocular, siendo suficientes treinta minutos para que ocurra daño visual permanente. Por sus secuelas el tratamiento del HO debe ser rápido y agresivo. Presentamos el caso de un varón de 72 años con diagnóstico de rinosinusitis crónica con pólipos nasales refractaria a tratamiento médico que se sometió a cirugía endoscópica nasal y que desarrolló en el posoperatorio inmediato con un HO. Se manejó precozmente con cantotomía-cantolisis, descompresión orbitaria medial endoscópica y control vascular de la AEA. El paciente evoluciona favorablemente, sin déficit visual. En este artículo se discutirán el diagnóstico y manejo oportunos del hematoma orbitario iatrogénico.

Abstract During endoscopic sinonasal surgery, inadvertent section of the anterior ethmoidal artery (AEA) with retraction into the orbit is the usual mechanism of orbital hematoma (OH), leading to proptosis, pain, and potentially irreversible visual loss. Thirty minutes is sufficient for retinal ischemia and permanent visual loss. The explanation for blindness is due to increased intraorbital pressure. The treatment of iatrogenic HO must be quick and aggressive, because if it is not managed in time, it can cause a permanent visual deficit. We present the case of a 72-year-old man with a diagnosis of chronic rhinosinusitis with nasal polyps refractory to medical treatment who underwent nasal endoscopic surgery, evolving in the immediate postoperative period with an HO, requiring canthotomy - cantolysis and early surgical reintervention for endoscopic medial orbital decompression and vascular control of AEA. The patient evolves favorably, without visual deficit. This article will discuss the timely diagnosis and management of iatrogenic orbital hematoma.

Queratoquistes odontogénicos maxilares en paciente con síndrome de Gorlin. Descripción de un caso y revisión de la literatura / Maxillary odontogenic keratocysts in a Gorlin síndrome patient: Case report and literatura review

Los queratoquistes maxilares son frecuentes en pacientes con síndrome de Gorlin. Su tratamiento es debatido por su alta tendencia a la recidiva. En los últimos años la cirugía endoscópica nasosinusal ha adquirido importancia en el manejo de esta patología. Exponemos en caso de un varón de 16 años afecto de este síndrome con queratoquistes maxilares donde se realiza un abordaje combinado, endonasal y transoral.

Maxillary keratocysts are frequent in Gorlin Syndrome patients. Its treatment is discussed due to the high tendency to recurrence. In the last years the sinonasal endoscopic surgery has become an important tool in the management of this pathology. We report a 16 years old boy with Gorlin Syndrome and maxillary keratocysts treated with a trans-nasal endoscopic and intra-oral combined approach.

Navigation and non-navigation CT scan of the sinuses: comparison of the effective doses of radiation in children and adults.

BACKGROUND: The advent of 3D navigation imaging has opened new borders to the endoscopic surgical approaches of naso-sinusal inflammatory and neoplastic disease. This technology has gained in popularity among otolaryngologists for endoscopic sinus and skull base surgeries in both adults and children. However, the increased tissue radiation required for data acquisition associated with 3D navigation protocols CT scans is a source of concern because of its potential health hazards. We aimed to compare the effective doses of radiation between 3D navigation protocols and standard protocols for sinus computed tomography (CT) scans for both the adult and pediatric population. METHODS: We performed a retrospective cohort study through electronic chart review of patients undergoing sinus CT scans (standard and 3D navigation protocols) from May 2019 to December 2019 using a Siemens Drive (VA62A) CT scanner. The effective dose of radiation was calculated in mSv for all exams. Average irradiation doses were compared using a Student's T-Test or a Kruskall-Wallis test when appropriate. RESULTS: A total of 115 CT scans were selected for analysis, of which 47 were standard protocols and 68 were 3D navigation protocols CT scans. Among these, 31 exams were performed on children and 84 exams on adults. For the total population, mean effective dose in the non-navigation CT scans was 0.37 mSv (SD: 0.16, N = 47) and mean effective dose in the 3D navigation sinus CT group was 2.33 mSv (SD: 0.45, N = 68). The mean difference between the two groups was statistically significant 1.97 mSv (CI 95% - 2.1 to - 1.83; P < 0.0001). There was a sixfold increase in radiation with utilization of 3D navigation protocols. The ratio was identical when the pediatric as well as the adult subset of patients were analyzed. CONCLUSION: In our center, utilization of 3D navigation sinus CT protocols significantly increases radiation exposure. Otolaryngologists should be aware of this significant increase and should attempt to decrease the radiation exposure of their patients by limiting unnecessary scan orders and by evaluating 3D acquisition protocols locally with radiation physicists. LEVEL OF EVIDENCE: Level IV.

Creation and validation of a radiological checklist for functional endoscopic sinonasal surgery. A YO-IFOS initiative.

BACKGROUND: Functional endoscopic sinus surgery might lead to dangerous complications. Studying and analysing preoperative CT scans provides surgeons with a precise knowledge of their patient's anatomy, thus reducing the risk of potential complications. Checklists highlighting key anatomical areas have been published and proven useful. However, none of these are widely accepted or systematically used in daily practice. OBJECTIVE: In this paper, the rhinology group of the Young-Otolaryngologists of the International Federations of Otorhinolaryngological Societies (YO-IFOS) aim to create and validate a new checklist designed to be fast and user friendly for daily practice. METHODS: Two CT sinonasal scans were selected as test cases. Forty otolaryngologists were selected from five tertiary referral hospitals. It was a cross-sectional study; each participant was their own control. All participants completed a questionnaire after the analysis of both CT scans to prevent learning bias. The evaluation included ten items critical in endoscopic sinus surgery according to previous publications. RESULTS: There were 80 evaluations. There was a significant increase in the number of correctly identified critical structures with the use of the checklist (p=.009). There was a statistically significant difference in low- experience evaluators, while it was not statistically significant for experienced surgeons. The most unanswered structures were suprabullar recess, dangerous v2 nerve, anterior ethmoid artery, dangerous vidian nerve and Onodi cell. The most wrongly identified structures were Keros type, septal deviation and cribiform middle turbinate. CONCLUSION: The YO-IFOS radiological checklist has proven a useful tool for correctly studying sinonasal anatomical variations. There is a clear learning component in the use of the checklist although it does not in any way exempt specialists from thorough study of sinonasal anatomy. Given the risk-benefit ratio, we strongly suggest the routine use of the checklist to systematically assess CT-scans prior to endoscopic sinonasal surgery.

Objetivo: La cirugía endoscópica nasosinusal (CENS) tiene complicaciones peligrosas. El estudio peroperatorio de la tomografía nasosinusal otorga un conocimiento preciso de la anatomía del paciente, reduciendo así el riesgo de complicaciones. Se han publicado listas de comprobación para cirugía nasosinusal, y estas han demostrado su utilidad. En este trabajo, desde el grupo de rinología de Young-Otolaryngologists of the International Federations of Oto-rhino-laryngological Societies (YO-IFOS), se diseñó y validó una lista de comprobación con el objetivo de ser amplia, cómoda y práctica para uso en la práctica clínica diaria.MétodosSe seleccionaron 2 tomografías nasosinusales como caso problema. Cuarenta otorrinolaringólogos fueron reclutados de 5 centros de tercer nivel. Se diseñó un estudio cruzado, por lo que cada participante fue su propio control. Todos los participantes completaron una evaluación tras el análisis de ambos casos con el objetivo de evitar sesgo de aprendizaje.ResultadosSe completó un total de 80 evaluaciones. El uso del checklist supuso una mejoría en el número de variantes peligrosas identificadas (p=0,009). La diferencia fue estadísticamente significativa para evaluadores poco experimentados, pero no para los experimentados. Las variantes con mayor número de respuestas en blanco fueron el receso suprabullar, el nervio V2, la arteria etmoidal anterior, el nervio vidiano y la celda de Onodi. Las estructuras con mayor número de error fueron Keros, desvío septal e inserción del cornete medio en lámina cribosa. (AU)

Carcinoma neuroendocrino moderadamente diferenciado (carcinoide atípico) de cavidad nasal: Reporte de un caso y revisión del tema / Moderately differentiated neuroendocrine carcinoma of the nasal cavity, a case report and literature review

Resumen Los carcinomas neuroendocrinos son tumores poco frecuentes en nariz y senos paranasales. Se consideran tumores primitivos y son los menos diferenciados del sistema neuroendocrino difuso. Se discute el caso de una paciente femenina de 49 años quien acude al servicio de otorrinolaringología en el Hospital Central Militar refiriendo masa en cavidad nasal izquierda de crecimiento progresivo en un periodo de 9 meses, así como epistaxis y obstrucción nasal izquierda. Mediante resonancia magnética y tomografía computada se observó tumoración de la cavidad nasal izquierda en su totalidad hasta nasofaringe, con captación heterogénea del medio de contraste. Se decide resección de tumoración mediante abordaje endoscópico (sinusotomía maxilar tipo III, etmoidectomía anterior y posterior izquierda, Draf esfenoidal tipo II izquierdo, Draf IIa del seno frontal izquierdo, así como septectomía posterior). El estudio histopatológico reportó un carcinoma neuroendocrino moderadamente diferenciado, por lo que se trató de forma conjunta con servicio de oncología médica. Este tipo de tumores son un reto diagnostico por la complejidad para diferenciarlos en un estudio histopatológico. La diferenciación efectiva de los mismos puede tener un impacto clínico, por lo que los avances en la intervención terapéutica podrían prolongar la supervivencia del paciente, mejorar la calidad de vida e incluso la cura.

Abstract Neuroendocrine carcinomas are rare tumors of the nose and sinuses. They are considered primitive tumors and are the least differentiated from the diffuse neuroendocrine system. We report a 49-year-old female patient who attends the otolaryngology service at the Central Military Hospital referring mass in the left nasal cavity with a progressive growth over a period of 9 months, including epistaxis, as well as left nasal obstruction. Magnetic Resonance Imaging and Computed Tomography imaging studies showed a tumor occupying the entirety of the left nasal cavity to the nasopharynx, with heterogeneous uptake of the contrast medium. Tumor resection is decided by endoscopic approach (maxillary sinusotomy type III, left anterior and posterior ethmoidectomy, left sphenoid Draf type II, left frontal Draf IIa as well as posterior septectomy). The pathology service reported a moderately differentiated neuroendocrine carcinoma. The treatment was decided joint session with the medical oncology service. These types of tumors are a diagnostic challenge because of the complexity to differentiate them in a histopathological study. Their effective differentiation can have a clinical impact, that's why the advances in therapeutic intervention could prolong patient survival, improve quality of life and even find a cure.

Usefulness of endonasal mucoplasty in the surgical treatment of chronic rhinosinusitis with nasal polyps. Prospective study.

Chronic Rhinosinusitis with Nasal Polyps (CRScPN) is a disease with great impact on health. The surgical option using endoscopic nasosinus surgery is the therapeutic alternative when control of the disease is not achieved with medical treatment. Extensive endoscopic approaches are being postulated as a possible best surgical treatment option in certain phenotypes of CRScPN. Endonasal mucoplasty associated with these approaches has been shown to be a complementary technique that improves both healing and mucosal oedema in patients with CRScPN in the short term. The aim of our study was to analyse the results of endonasal mucoplasty associated with a complete ethmoid-sphenoidotomy plus grade III frontal sinusotomy in the treatment of CRScPN in the medium term. For this purpose, a prospective case-control study (10/10) was carried out on patients with CRScPN. In the case group, endonasal mucoplasty in the left nostril was associated with surgery, and the control group was not. The assessment of quality of life at one year after surgery, as measured by the mean difference in SNOT-22 (mean [SD]), in the case group was significantly better than in the control group, (45.9 [19.6]-26.6 [16.05], P = 0.027). The endoscopic improvement in healing and mucosal oedema, measured by the Modified Lund-Kennedy scale, showed relevant improvements, when comparing both pits, but without reaching significance (P = 0.29). Endonasal mucoplasty promotes short-term healing, improving the quality of life in the medium term (one year) of patients treated with extensive endoscopic breast resections.

Utilidad de la mucoplastia endonasal en el tratamiento quirúrgico de la rinosinusitis crónica con pólipos nasales. Estudio prospectivo / Usefulness of endonasal mucoplasty in the surgical treatment of chronic rhinosinusitis with nasal polyps. Prospective study

La rinosinusitis crónica con pólipos nasales (RSCcPN) es una enfermedad con gran impacto sobre la salud. La opción quirúrgica mediante cirugía endoscópica nasosinusal es la alternativa terapéutica cuando no se alcanza el control de la enfermedad con el tratamiento médico. Los abordajes endoscópicos extensos se están postulando como posible mejor opción de tratamiento quirúrgico en ciertos fenotipos de RSCcPN. La mucoplastia endonasal asociada a estos abordajes ha demostrado ser una técnica complementaria que mejora tanto la cicatrización como el edema mucoso a corto plazo en pacientes con RSCcPN. El objetivo de nuestro estudio ha consistido en analizar los resultados de las mucoplastia endonasal asociada a una etmoidoesfenoidotomía completa más sinusotomía frontal de grado III en el tratamiento de RSCcPN a medio plazo. Para ello se realizó un estudio prospectivo de casos y controles (10/10) en pacientes con RSCcPN. En el grupo de casos se asoció a la cirugía una mucoplastia endonasal en la fosa nasal izquierda y en el grupo control no. La evaluación de la calidad de vida al año de la intervención quirúrgica, medida mediante la diferencia de medias de SNOT-22 (media [DE]), en el grupo de casos fue significativamente mejor que en el grupo control (45,9 [19,6]-26,6 [16,05]; p=0,027). La mejoría endoscópica de la cicatrización y del edema mucoso, medida mediante la escala de Lund-Kennedy modificada, mostró mejorías relevantes al comparar ambas fosas, pero sin alcanzar la significación (p=0,29). La mucoplastia endonasal favorece la cicatrización a corto plazo, lo que mejora la calidad de vida a medio plazo (un año) de los pacientes tratados con resecciones extensas endoscópicas de los senos.

Angiomiolipoma nasal: reporte de dos casos y revisión de la literatura

Resumen El angiomiolipoma es una lesión hamartomatosa, habitualmente de localización renal asociado a esclerosis tuberosa. La ubicación nasosinusal es extremadamente infrecuente y se puede presentar con obstrucción nasal y epistaxis. Se presentan dos casos de angiomiolipoma de cavidad nasal diagnosticados en el Hospital Carlos Van Buren de Valparaíso. Ambos casos se presentaron como masa nasal unilateral, se estudiaron con tomografía computada y fueron tratados con biopsia escisional, sin presentar recidivas durante su seguimiento. El anigiomiolipoma está compuesto por vasos sanguíneos, músculo liso y adipocitos. Existen diferencias entre el angiomiolipoma del riñón versus el de piel, cavidad oral y nasal (angiomiolipomas mucocutáneos); estos últimos son extremadamente infrecuentes, de menor tamaño, con presencia de agregados linfoides, negativos para antígeno específico de melanoma HMB-45 y sin asociación a esclerosis tuberosa. Existen pocos casos reportados en la literatura de esta patología, por lo que existe poca evidencia. Clínicamente, se presentan con obstrucción nasal, epistaxis recurrente, sensación de masa nasal. El estudio preoperatorio depende de su extensión y puede incluir una tomografía computada y/o angiografía para identificar su irrigación. El diagnóstico definitivo es anatomopatológico. Si se logra la escisión completa, no se han reportado recidivas, por lo que presenta un excelente pronóstico.

Abstract Angiomyolipoma is a hamartomatous lesion, usually of a renal location associated with tuberous sclerosis. Nasosinusal location is extremely rare and can present with nasal obstruction and epistaxis. Two cases of angiomyolipoma of the nasal cavity diagnosed at the Carlos Van Buren Hospital in Valparaíso are presented. Both cases presented as a unilateral nasal mass, and were studied with computed tomography, and treated with an excisional biopsy, with no recurrences during follow-up. Anigiomyolipoma is composed of blood vessels, smooth muscle and adipocytes. There are differences between angiomyolipoma of the kidney versus skin, oral and nasal cavity (mucocutaneous angiomyolipomas). The latter are extremely infrequent, smaller in size, with the presence of lymphoid aggregates, negative for the HMB-45 specific melanoma antigen and without association with tuberous sclerosis. There are few cases reported in the literature of this pathology, so there is little evidence. Clinically, they present with nasal obstruction, recurrent epistaxis, sensation of nasal mass. The preoperative study depends on its extension and may include a computed tomography and/or angiography to identify its irrigation. The definitive diagnosis is pathological. If complete excision is achieved, no recurrences have been reported, so it has an excellent prognosis.

[IManagement of patients with relapsed primary naso-sinusal tuberculosis]. / Gestion de la rechute d'une tuberculose naso-sinusienne primaire.

Primary naso-sinusal tuberculosis (TB) is a relatively rare or exceptional disorder characterized by polymorphic or non-specific clinical manifestation. Diagnosis is based on anatomo-pathological examination and mycobacteriology test of biopsy specimen. Predictor of good outcome is early conventional anti-tuberculous antibiotic therapy. However, our study reports recurrence at this rare site in an immunocompetent patient despite early suitable TB treatment and good adherence with therapy. Relapse was correlated with underdosing of rifampicin. This study highlights the diagnostic, etiological and therapeutic management of this relapse. Our experience could help clinicians to better manage this uncommon condition.

Evaluación radio-anatómica del receso del seno frontal en población colombiana / Radio-anatomic evaluation of the frontal sinus recess in colombian population

Objetivos: La cirugía endoscópica del seno frontal es quizá uno de los procedimientos más complejos en el manejo endoscópico de los senos paranasales debido a su localización y a las múltiples variantes anatómicas que pueden encontrarse durante su disección. Es indispensable conocer al detalle la anatomía quirúrgica de esta región en nuestra población, para optimizar la planeación quirúrgica de los pacientes. Actualmente en nuestro país se desconoce la frecuencia de estas variaciones. El objetivo del proyecto es evaluar la frecuencia de las variables anatómicas del seno frontal y realizar un estudio radio-anatómico en una muestra de pacientes en Colombia. Diseño del estudio: Observacional, descriptivo de tipo transversal. Métodos: Muestra aleatorizada de 406 tomografías computarizadas de senos paranasales que incluyeron 812 senos frontales recolectados durante el año 2018 Resultados: La celdilla suprabular fue la más comúnmente reportada con una frecuencia de 59.61%. La segunda celdilla fue la supra agger nasi con una frecuencia de 57.88%, seguido de la celdilla supra agger frontal (25.12%), celdilla suprabular frontal (22.17%), celdillas supraorbitarias (34.98%) y las celdilla frontal intersinusal (24,14%). La arteria etmoidal anterior se reportó colgante en un 31.28% y el diámetro AP más frecuente fue entre 5 -10 milímetros. Conclusiones: Para realizar una sinusotomía frontal endoscópica de forma adecuada es necesario conocer al detalle la anatomía del receso del seno frontal. Las diferentes variantes radio-anatómicas son muy frecuentes en el grupo poblacional estudiado. Creemos que este trabajo permitirá a los cirujanos un mejor entendimiento de esta región de difícil acceso quirúrgico en nuestra población. Palabras clave: Seno frontal, senos paranasales, seno clasificación frontal, cirugia endoscopica nasosinusal

Objectives: Endoscopic frontal sinus surgery is perhaps, one of the most complex procedures in the endoscopic sinus surgery, due to its anatomical location and the multiple anatomical variants that can be found. It is essential to know in detail the anatomy of this region in order to obtain a better understanding for the surgical planning. Currently, the frequency of these anatomical variations remains unknown in our country. Therefore, the objective of the study is to evaluate the frequency of the anatomical variants of the frontal sinus and to carry out a radio-anatomic study in a sample of patients from Colombia. Study design: Observational, cross-sectional descriptive. Methods: Randomized sample of 406 CT scan of the paranasal sinuses that included 812 frontal sinuses collected during the year 2018. Results: The supra bulla cell was the most frequently reported with a frequency of 59.61%. The second cell was the supra agger (57.88%) followed by supra agger frontal cell (25.12%), supra bulla frontal cell (22.17%), supraorbital ethmoid cells (34,98%) and frontal septal cell (24,14%) . The anterior ethmoidal artery was found hanging in 31.28% and the most frequent AP diameter was between 5 -10 mm. Conclusions: To perform an appropriate endoscopic frontal sinusotomy, it is necessary to know in detail the anatomy of the frontal sinus recess. The different radio-anatomical variants of the frontal sinus are very frequent in the population group studied. We believe that this study will allow surgeons to obtain a better understanding of this anatomical region of difficult surgical access.

Poliposis nasosinusal / Nasosinusal Polyposis

La poliposis nasosinusal, es una entidad caracterizada por un proceso inflamatorio de la mucosa nasosinusal, con sintomatología obstructiva, para su diagnóstico es necesario la exploración endoscópica y la tomografía computarizada, siendo la cirugía endoscópica nasosinusal, el tratamiento recomendado. Objetivo:recopilar información actualizada acerca de la poliposis nasosinusal con respecto a su fisiopatología, diagnóstico y tratamiento. Material y Métodos: se realizó la búsqueda de artículos en las bases de datos como HINARI, SciELO, Biblioteca Cochrane, PubMed, con las palabras clave rinosinusitis polipoide y poliposis nasosinusal, en inglés y español; se encontraron varios artículos, de los cuales se seleccionaron 20, de revistas biomédicas publicadas en los últimos 5 años y según su importancia de los conceptos básicos de esta entidad. Conclusión: existe debate en la fisiopatología de la poliposis nasosinusal, aunque se acepta la teoría alérgica y la reacción inflamatoria como las causas. Además, el manejo medicamentoso, no es un tratamiento definitivo, teniendo que recurrir al tratamiento quirúrgico para mejorar la sintomatología, donde el tratamiento recae principalmente, en la cirugía endoscópica nasosinusal...(AU)

[IgG4 related disease with exclusive sinonasal involvement: A case report and literature review]. / Enfermedad relacionada con IgG4 con afectación exclusiva nasosinusal: presentación de un caso clínico y revisión de la literatura.

IgG4 related disease (igG4-RD) is a pathological process which integrates a large number of diseases of unknown pathogenesis, considered as being exclusive to many different organs. Diagnosis is established through histological, radiological and serological criteria. Treatment is based on long term corticosteroids; rituximab being used only in refractory cases. It is unusual for this entity to be found exclusively in the head and neck, without systemic involvement; there are only a few reported cases to date. We present a case of a nasosinusal IgG4-RD orbital tumor with paranasal sinus involvement. The accurate diagnosis made early onset corticosteroid treatment possible and the patient is currently asymptomatic.

Management of severe and/or refractory epistaxis. / Manejo de las epistaxis graves y/o refractarias.

OBJECTIVE: The objective was to determine the results of the treatment of severe and/or refractory epistaxis requiring hospital admission. In addition, the results of arterial ligation versus embolization were compared. MATERIAL AND METHOD: Sixty-three patients with severe and/or refractory epistaxis requiring hospital admission between August 2014 and December 2016 were included prospectively. RESULTS: Eleven patients (17%) underwent embolization, 5 (8%) endoscopy ligation and the remaining 47 (75%) underwent conservative treatment with tamponade. The mean age of the patients in which conservative measures were sufficient was 72 years, while the age of those treated with embolization was 71 years and of those who underwent surgery was 53 years. For the patients who underwent conservative treatment or surgery, the average stay was 6 days, compared to 9 days for those who underwent embolization. One patient suffered a hemispheric stroke after embolization. No post-surgical complications were observed. CONCLUSIONS: Most cases of severe and/or refractory epistaxis are resolved by conventional tamponade. Endoscopy ligation is associated with a decrease in hospital stay, without serious complications. It is advisable to have all the possible therapeutic options available, for which the presence of interventional radiologists and experienced surgeons is essential to avoid complications and decide the treatment to be performed individually for each patient.

The endoscopic endonasal approach for the treatment of juvenile angiofibromas. / Abordaje endoscópico endonasal para el tratamiento de los angiofibromas juveniles.

BACKGROUND AND OBJECTIVES: Juvenile angiofibroma (JA) is a benign tumour, for which the treatment of choice is surgery. It may be associated with significant morbidity because of its anatomical location and its locally destructive growth pattern. Severe haemorrhage constitutes a high risk in JA and its surgical management can be complex. The management of JA remains a challenge. The objective of this study was to review a series of patients with JA treated via the endonasal/endoscopic approach. MATERIAL AND METHODS: Medical records of patients operated for JA were reviewed. MAIN OUTCOME MEASURES: tumour stage, intraoperative blood loss, complications and persistence/recurrence rates. RESULTS: A total of 30 male patients and one female were included. The mean age was 17 years. Using the Radkowski classification, one JA was classified as stage I, 5 stage IIA, 9 stage IIB, 4 stage IIC, 10 stage IIIA and 2 stage IIIB. Thirty-nine percent of the JA was classified as advanced stage JA (IIIA and IIIB). The mean blood loss was 1.156mL Except in one case, no significant complications were observed. Tumour persistence/recurrence was observed in 2 JA (6%), at the end of the follow-up. Mean postoperative follow-up time was 86 months. CONCLUSIONS: This retrospective study supports the notion that endonasal endoscopic approaches for a JA are a feasible option associated with good long-term results.

[Nasal NK/T-cell lymphoma: about two rare cases]. / Lymphome T/NK nasal: à propos de deux cas rares.

NK/T-cell lymphoma is a severe and rare disorder in Africa and in Europe. Treatment is based on radiotherapy and chemotherapy. We here report two cases of elderly patients aged 55 years and 52 years, respectively, with bilateral nasal obstruction associated with purulent rhinorrhea. Clinical examination showed cleft palate. Diagnosis was made on the basis of immunohistochemical examination of biopsies. Both patients underwent CHOEP chemotherapy followed by radiotherapy. Nasal NK/T-cell lymphoma is an aggressive type of non-Hodgkin's lymphoma with specific clinicopathologic features. Combining chemotherapy with radiotherapy in patients with advanced stage of the disease does not seem to improve survival compared with radiotherapy alone, which is the treatment of choice especially for localized stages. Nasal NK/T-cell lymphoma is rare. Diagnosis is based on immunohistochemical examination. Treatment includes chemotherapy and radiotherapy. This lymphoma has a poor overall prognosis, even with appropriate therapy.

Manejo endoscópico de osteoma etmoidal con extensión orbitaria: a propósito de un caso / Endoscopic manegement of frontoethmoidal osteoma: on case subject

El osteoma es el tumor más frecuente de los senos paranasales, habitualmente asintomático debido a su lento crecimiento, sin embargo, pueden desarrollarse síntomas dependiendo del tamaño, localización y extensión, con potencial compromiso de órbita y cerebro. La cirugía está indicada en casos sintomáticos pudiendo realizarse abordaje externo, endoscópico o combinado. Presentamos un caso de osteoma etmoidal con compromiso orbitario resuelto, manejado por medio de la cirugía endoscópica nasal, con apoyo de navegación.

The osteoma is the most common tumor of the paranasal sinuses, is usually asymptomatic because of their slow growth, however, may develop symptoms depending on the size, location and extent, with potential compromise of orbit and brain. Surgery is indicated in symptomatic cases, with external, endoscopic or combined approach. We present a case of ethmoidal osteoma with orbital involvement managed by endoscopic image guided surgery.
