ABSTRACT Introduction Sinonasal inverted papillomas are benign tumors with a tendency to recur and a potential for malignant transformation. Surgical resection is the treatment of choice. Aim To describe and analyze the clinical characteristics, epidemiology, and surgical results from an endoscopic endonasal approach. Material and method Retrospective and descriptive study of all patients who underwent endoscopic sinus surgery for the treatment of a sinonasal inverted papilloma between the years 2012 and 2016. Variables analyzed include demographics, signs and symptoms, surgical complications, recurrence rate and malignant transformation. Tumor extension was evaluated with the Krouse staging system on computed tomography imaging. Results This series includes 18 patients, with a mean age of 57.4 years. Clinically, patients presented with unilateral nasal obstruction 72.2% (13/18 patients), followed by rhinorrhea 33.3% (6/18 patients), hyposmia 27.8% (5/18 patients) and epistaxis 27.8% (5/18 patients). Based on the Krouse staging system, 7/18 were T1, 5/18 were T2, 5/18 were T3 and 1/18 was T4 on initial evaluation. On follow-up, 4 patients presented with a recurrence at a mean period of 5.6 months, and one patient exhibited malignant transformation. No surgical complications were observed except for one case of epyphora as a consequence of nasolacrimal obstruction. Conclusions The endoscopic approach was effective for the treatment of sinonasal inverted papillomas.

Introducción: El papiloma invertido es uno de los tumores benignos más frecuentes de la región nasosinusal. Los principales problemas en su manejo son la recurrencia y transformación maligna. Su tratamiento es la extirpación quirúrgica. Objetivos: Describir y analizar las caracterfsticas cínicas y epidemiológicas, así como el resultado del tratamiento endoscópico practicado en el Hospital Clínico Regional de Concepción. Material y método: Se realizó un estudio retrospectivo, descriptivo, de todos los pacientes con diagnóstico de papiloma invertido nasosinusal operados vfa abordaje endoscópico entre los años 1997 y 2012. Se analizaron variables epidemiológicas y clínicas, incluyendo análisis de las recurrencias y transformación/asociación a cáncer. Resultados: Se encontraron 57 casos de papiloma invertido nasosinusal, 55 de los cuales se abordaron endoscópicamente, 65,5% hombres, 54,7 años en promedio de edad. La obstrucción nasal fue el principal síntoma. La mayor cantidad se concentró en estadio 2 (47,3%) y 3 (32,7%) de Krouse. Complicaciones relevantes 7,8%, las cuales fueron resueltas sin secuelas. Seguimiento promedio de 4,1 años, con una recurrencia de 5 (9,1%) casos, una persistencia (1,8%). Asociación con carcinoma escamoso en el 5,5% de los casos. Conclusión: La experiencia con la resección endoscópica en el papiloma invertido nasosinusal ha demostrado ser efectiva en nuestro medio, con baja tasa de complicaciones y recurrencias.
Introduction: The inverted papilloma is one of the most common benign tumors of the sinonasal region. The main problems in their management are the recurrence and malignant transformation. Their treatment is surgical removal. Aim: To describe and analyze the clinical and epidemiological characteristics, as well as the results of endoscopic treatment in a tertiary hospital. Materials and methods: A retrospective, descriptive study of all patients with diagnosis ofsinonasal inverted papilloma operated by endoscopic approach between 1997 and 2012 was carried out. Epidemiological and clinical variables were analyzed, including analysis of recurrences and transformation to / association with cancer. Results: 57 cases of sinonasal inverted papilloma were found, 55 of which were endoscopically resected, 65.5% male, 54.7 years old on average. Nasal obstruction was the main symptom. Most of them were in Krouse stage 2 (47.3%) and 3 (32.7%); 7.8% of major complications, which were resolved without sequels. The follow up average was 4.11 years, with a recurrence of 5 (9.1%) cases, and (1.8%) persistence. Association with squamous-cell carcinoma was found in 5.5% of cases. Conclusion: The clinical and epidemiological characteristics do not differ greatly from those reported in the literature. Experience with endoscopic resection in sinonasal inverted papilloma has proven effective in our clinical practice, with a low rate of complications and recurrences, this approach currently being the first choice in most cases.

Introducción: El papiloma invertido es un tumor benigno que afecta fosas nasales y senos paranasales; histológicamente se clasifica en oncocítico, invertido y fungiforme. Los signos y síntomas son obstrucción nasal unilateral, rinorrea, cefalea, epistaxis, anosmia. El diagnóstico de certeza es por anatomía patológica; se utilizan además métodos de diagnóstico por imagen para determinar la extensión tumoral. Existe cierto porcentaje de asociación de esta patología al carcinoma escamoso. El tratamiento es quirúrgico. Objetivo: Evaluar las características clínicas y quirúrgicas de papilomas invertidos operados en la Cátedra de ORL del Hospital de Clínicas de la Facultad de Ciencias Médicas, Universidad Nacional de Asunción, Paraguay (UNA). Material y método: En este trabajo de carácter observacional y descriptivo se estudiaron los casos de papiloma invertido operados en el Hospital de Clínicas entre los años 1994 a 2008, mediante revisión de fichas de casos consecutivos, analizando las cirugías realizadas. Resultados: Treinta casos de los cuales la mayoría fue de estadio II y III de Krause, con una recidiva global del 30 por ciento con una malignización del 17 por ciento. Discusión: En esta serie de pacientes se vio tumores con poca extensión pero con una transformación maligna presente, elevándolos al estadio IV de Krause. Conclusión: Se sugiere intentar la mayor radicalidad posible siempre con el total consentimiento y conocimiento del paciente.
Introduction: Inverted papilloma is a benign tumor that affects nasal cavity and Para nasal sinuses; histologically classified as oncecitas, inverted papillomas and fundiform or exophytic. Signs and symptoms include unilateral nasal obstruction, rhino rhea, headache, epitasis, and anosmia. The certainty diagnosis is given by pathology and in diagnosis are used imaging methods to determine the extent of the tumor. There is a certain percentage of association of this pathology with squamous carcinoma. The treatment is surgical. Aim: To evaluate the clinical and surgical characteristics of inverted papillomas that were operated in the Department of ENTin the Hospital School of Medical Sciences, UNA. Material and method: In this observational and descriptive work were studied cases of inverted papilloma operated at the Hospital from 1994 to 2008, by reviewing records of consecutive cases and analyzing the surgeries performed. Results: 30 cases in which the majority were Stage II and III of Krause, with an overall of 30 percent, relapse with a malignancy of 17 percent. Discussion: In this series of patients we observed tumors with low extension but with malignant transformation which elevated them to stage IVKrause. Conclusión: We suggest trying the most radical possible surgery provided with the fuII consent and knowledge of the patient.

OBJECTIVE: To evaluate the clinicopathological profile of sinonasal inverted papilloma in a tertiary referral center in eastern part of Nepal. METHODS: A prospective study consisting of total 28 histologically proven cases of sinonasal inverted papilloma was conducted in the ENT department of the center. The study period was from April 2002 to November 2005. RESULT: Out of 28 cases studied, 21 were males and 7 were females with male to female ratio of 3:1. The highest incidence was seen in the 5th and 6th decades of life. The duration of symptoms varied from 5 months to 20 years with mean duration of 3.9 years. The lateral nasal wall and nasal cavity involvement was seen in all 28 cases. Maxillary sinus was involved in 27(96.4%) subjects followed by ethmoid (20), sphenoid (10) and the frontal sinus (7). The principle presenting symptom was nasal obstruction seen in 96.4% of the patients. Twenty two cases were treated by lateral rhinotomy with medial maxillectomy while, orbital exenteration was done in two cases. Associated carcinoma was noticed in 10.15% of all the subjects studied. CONCLUSION: Sinonasal papilloma mostly presented in fifth to six decades of life mainly affecting the male patients. Majority of the patients were treated by lateral Rhinotomy with medial maxillectomy surgery. Early presentation would have given chances for endoscopic surgery.
