Abstract Introduction Sinonasal inverted papilloma is noted for its high rate of recurrence. Staging systems aid to reduce recurrence and avoid excessive surgeries by guiding the selection of the optimal surgical approach. Objective To evaluate the effectiveness of different endoscopic approaches in inverted papilloma by assessing tumor origin site and tumor volume. Methods Krouse classification system that is based on tumor volume was used for staging; furthermore, tumor origin sites were grouped as lateral nasal wall, medial wall and other walls of maxillary sinus. The main treatment method for all patients was endoscopic sinus surgery. Endoscopic extended middle meatal antrostomy, endoscopic Caldwell-Luc and endoscopic medial maxillectomy were the additional surgery types performed in different combinations. Results Fifty-five patients (42 male) with a mean 54.9 ± 14.4 years of age were included. 37 patients were diagnosed with advanced stage inverted papilloma (67.2 %). Recurrence was observed in 12 patients (21.8 %). In early stage lateral nasal wall origination, no recurrence was observed in the simple tumor resection group (0/10). In early stage medial wall origination, no recurrence was observed in the extended middle meatal antrostomy group (0/8). In advanced stage medial wall origination, the recurrence rates of extended middle meatal antrostomy, extended middle meatal antrostomy + endoscopic Caldwell- Luc and endoscopic medial maxillectomy were 100.0 %, 53.8 % and 13.6 %, respectively (p = 0.002). In advanced stage other walls of maxillary sinus origination, recurrence rates of extended middle meatal antrostomy + endoscopic Caldwell-Luc and endoscopic medial maxillectomy were 20 % and 16.6 %, respectively (p = 0.887). Conclusion Tumor origin site, tumor stage and surgery types show an impact on recurrence. Despite the fact that tumor origin site singly could lead to appropriate selection of the surgery type in most cases, tumor stage carries substantial importance in selection of surgery type for sinonasal-inverted papilloma. An operation plan regarding both tumor volume and tumor origin site may aid surgeons in selecting optimal endoscopic surgical method to avoid recurrence or excessive surgeries.

Resumo Introdução O papiloma invertido nasossinusal é conhecido por sua alta taxa de recorrência. Os sistemas de estadiamento ajudam a reduzir a recorrência e evitar cirurgias excessivas e orientam a seleção da abordagem cirúrgica ideal. Objetivo Avaliar a eficácia de diferentes abordagens endoscópicas no papiloma invertido, de acordo com o local de origem e o volume do tumor. Método Para o estadiamento, usou-se o sistema de classificação de Krouse, baseado no volume do tumor; além disso, os tumores foram agrupados de acordo com seus locais de origem: parede nasal lateral, parede medial e outras paredes do seio maxilar. O principal método de tratamento para todos os pacientes foi a cirurgia endoscópica nasossinusal. Foram feitos, em diferentes combinações, os seguintes tipos de cirurgia: antrostomia estendida do meato médio, Caldwell-Luc endoscópica e maxilectomia medial endoscópica. Resultados Foram incluídos 55 pacientes (42 homens) com média de 54,9 ± 14,4 anos. Trinta e sete pacientes foram diagnosticados com papiloma invertido avançado (67,2%). Foi observada recorrência em 12 pacientes (21,8%). No estágio inicial com origem na parede nasal lateral, não foi observada recorrência no grupo de ressecção simples de tumor (0/10). No estágio inicial com origem na parede medial, não foi observada recorrência no grupo de antrostomia estendida do meato médio (0/8). Com tumor em estágio avançado com origem na parede medial, as taxas de recorrência na antrostomia estendida do meato médio, antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 100,0%, 53,8% e 13,6%, respectivamente (p = 0,002). No tumor em estágio avançado em outras paredes do seio maxilar, as taxas de recorrência na antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 20% e 16,6%, respectivamente (p = 0,887). Conclusão O local de origem do tumor, o estágio do tumor e os tipos de cirurgia mostram impacto na recorrência. Apesar da consideração de que na maioria dos casos o local de origem do tumor pode, de forma isolada, orientar a seleção apropriada do tipo de cirurgia, o estágio do tumor tem importância substancial na seleção do tipo de cirurgia para papiloma invertido nasossinusal. Um planejamento cirúrgico considerando tanto o volume quanto o local de origem do tumor pode ajudar os cirurgiões a selecionar o tipo ideal de cirurgia endoscópica para evitar recorrências ou remoções excessivas.

Abstract Introduction: Although sinonasal inverted papillomas are benign lesions, they are locally aggressive and have a potential malignant transformation ranging from 5% to 15%, with a high recurrence rate. Objective: The aim of this article is to describe the rate of recurrence and malignant transformation in patients with a diagnosis of inverted papilloma who underwent surgery in a tertiary hospital in São Paulo. Methods: We performed a retrospective analysis of patients diagnosed with sinonasal papilloma who had undergone surgery in a tertiary hospital in São Paulo, between August 1998 and August 2017. A patient chart review was conducted to assess data of patients' demographics, tumors characteristics, follow-up appointments, recurrence and malignancy. Inverted papillomas were analyzed and classified under the Krouse staging system. Results: A total of 69 surgeries were performed in patients with diagnosis of sinonasal papilloma. Inverted papilloma was the most prevalent subtype (49 cases ‒ 80.33%), followed by exophytic papilloma (6 cases ‒ 9.84%) and by oncocytic papilloma (6 cases - 9.84%). The recurrence rate was 34.09% for inverted papilloma (15/44) and the mean time of recurrence was 24.6 months. Malignant transformation occurred in 6 patients (13.64%). Three of these patients presented carcinoma in the first surgery and three patients developed carcinoma during the follow-up. Conclusion: The high recurrence rate and malignancy potential allow us to consider inverted papillomas as aggressive tumors. In a tertiary hospital in São Paulo the recurrence rate the mean time to recurrence is 24.6 months. The recurrence after 10 years implies was 34.09% and the need for long-term follow up. It is possible that the high recurrence rate and the high malignant transformation rate we found are due to the large number of tumors discovered at an advanced stage (most of them staged T3 and T4), secondary to poor access to health system, in developing countries.

Resumo Introdução: Embora os papilomas invertidos nasossinusais sejam lesões benignas, eles são localmente agressivos e apresentam uma potencial transformação maligna que varia de 5% a 15%, com alta taxa de recorrência. Objetivo: Descrever a taxa de recorrência e transformação maligna em pacientes com diagnóstico de papiloma invertido submetidos à cirurgia em um hospital terciário em São Paulo. Método: Análise retrospectiva dos pacientes diagnosticados com papiloma nasossinusal submetidos a cirurgia em um hospital terciário em São Paulo, entre agosto de 1998 e agosto de 2017. Uma revisão de prontuários dos pacientes foi realizada para avaliar dados demográficos, características dos tumores, consultas de seguimento, recorrência e malignidade. Os papilomas invertidos foram analisados e classificados de acordo com o sistema de estadiamento de Krouse. Resultados: Foram realizadas 69 cirurgias em pacientes com diagnóstico de papiloma nasossinusal. O papiloma invertido foi o subtipo mais prevalente (49 casos - 80,33%), seguido pelo papiloma exofítico (6 casos - 9,84%) e pelo papiloma oncocítico (6 casos - 9,84%). A taxa de recidiva foi de 34,09% para o papiloma invertido (15/44) e o tempo médio de recorrência foi de 24,6 meses. Transformação maligna ocorreu em seis pacientes (13,64%); três desses pacientes apresentaram carcinoma na primeira cirurgia e três pacientes desenvolveram carcinoma durante o seguimento. Conclusão: A alta taxa de recorrência e o potencial de malignidade nos permitem considerar os papilomas invertidos como tumores agressivos. Em um hospital terciário de São Paulo, a taxa de recorrência foi de 34,09% e o tempo médio de recorrência de 24,6 meses. A recorrência após 10 anos implica na necessidade de acompanhamento a longo prazo. É possível que a alta taxa de recorrência e a alta taxa de transformação maligna que encontramos sejam devidas à grande extensão dos tumores (a maioria deles nos estágios T3 e T4), decorrente do acesso precário ao sistema de saúde nos países em desenvolvimento.

Abstract Introduction: Inverted papillomas represent one of the most common benign neoplasic lesions located in the sinonasal tract. Owing to the local erosive behavior, tendency to recur and the potential for malignant transformation, surgical management of inverted papillomas is often challenging. Objective: This study aimed to analyze the surgical outcomes of patients with inverted papillomas, according to the Krouse staging and the different surgical approaches. Methods: Retrospective study of patients diagnosed with sinonasal inverted papillomas who underwent surgical treatment between 2000 and 2016 at a tertiary referral hospital. Cases with follow-up less than 12 months were excluded. The rate and the time of recurrence were the main outcomes. Values of p < 0.05 were considered statistically significant. Results: Thirty-six cases with mean age of 60 years, predominantly male (72%), were included. The follow-up period ranged from 1 to 16 years, with an average of 4.5 years. Krouse T1 Stage corresponded to 11.1%; T2 occurred in 50% of cases; while T3 and T4 Stages accounted for 30.6% and 8.3% of patients, respectively. Most cases were approached by an endoscopic technique alone (83.3%), with a recurrence rate of 13.3%. Patients treated via a combined or open approach revealed a recurrence of 16.7%. No differences in the recurrence rate were reported when comparing endoscopic surgery with the open or combined techniques. Krouse Stage T3 had a significant association with inverted papillomas recurrence (p = 0.023). All inverted papilloma relapses occurred up to 2 years post-operatively. One case of malignant transformation was recorded (2.7%). Conclusion: Endoscopic surgery did not increase the recurrence rates and can be a safe and efficient alternative to open or combined techniques. The recurrence of inverted papillomas seem to be related to the persistence of the disease and tend to occur early after primary surgery. Krouse T3 Stages may be associated with a higher recurrence of inverted papillomas.

Resumo Introdução: Os papilomas invertidos são uma das lesões neoplásicas benignas mais comuns no trato nasossinusal. Devido ao seu comportamento localmente agressivo, tendência para recidivar e potencial de malignização, o tratamento cirúrgico dos papilomas invertidos constitui frequentemente um desafio. Objetivo: Analisar os resultados cirúrgicos dos papilomas invertidos segundo o estadiamento de Krouse, bem como avaliar as diferentes abordagens cirúrgicas. Método: Estudo retrospectivo de pacientes com diagnóstico de papiloma invertido nasossinusal submetidos a tratamento cirúrgico entre 2000 e 2016 em hospital terciário. Casos com acompanhamento inferior a 12 meses foram excluídos. A taxa e o tempo de recidiva foram os principais resultados analisados desfechos avaliados. Valores p < 0,05 foram considerados estatisticamente significativos. Resultados: Foram incluídos 36 casos, com média de idade de 60 anos, predominantemente do sexo masculino (72%). O período de acompanhamento variou de 1 a 16 anos, em uma média de 4,5 anos. Relativamente ao estadiamento, 11,1% dos pacientes foram classificados como estadio Krouse T1, 50% como T2, 30,6% como T3 e 8,3% como T4. A maioria dos casos foi tratada exclusivamente por cirurgia endoscópica (83,3%), com taxa de recidiva de 13,3%. Pacientes tratados com uma técnica combinada ou aberta apresentaram recidiva de 16,7%. Não foram observadas diferenças quanto à taxa de recidiva entre os casos abordados por via endoscópica e os casos tratados com técnica aberta ou combinada. Verificou-se uma associação significativa entre o estadio T3 de Krouse e recidiva de papilomas invertidos (p = 0,023). Todas as recidivas de papilomas invertidos foram observadas até dois anos após a cirurgia. Um caso de transformação maligna foi registrado (2,7%). Conclusão: A cirurgia endoscópica não aumentou as taxas de recidiva e pode ser uma alternativa segura e eficiente às técnicas abertas ou combinadas. Os casos de recidiva do papiloma invertido parecem estar relacionados com a persistência da doença e tendem a ocorrer precocemente após a cirurgia primária. Os estadios T3 de Krouse podem estar associados a uma maior recidiva.

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.

RESUMEN La cirugía endoscópica nasosinusal es un procedimiento frecuente en la práctica otorrinolaringológica, y en la última década se han introducido nuevas técnicas para ayudar a la resección de tumores en regiones tradicionalmente consideradas de difícil acceso. Una de estas técnicas es el abordaje transeptal, que permite el abordaje de la pared anterior y lateral del seno maxilar, así como el trabajo a cuatro manos para el abordaje de estos tumores. El objetivo de esta revisión es describir el abordaje endoscópico transeptal, como técnica complementaria en la cirugía endoscópica de tumores nasales benignos, específicamente de papiloma invertido y angiofibroma nasofaríngeo juvenil.

ABSTRACT Endoscopic sinus surgery is a frequent procedure in Otorhinolaryngology practice, in the last decade new techniques have been introduced to help the resection of tumors in regions traditionally considered of difficult access. One of these techniques is the trans-septal approach, which allows the approach of the anterior and lateral wall of the maxillary sinus, as well as four-handed work for approach of these tumors. The aim of this review is to describe the transeptal endoscopic approach as a complementary technique in the endoscopic surgery of benign nasal tumors, specifically inverted papilloma and juvenile nasopharyngeal angiofibroma.

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.

Inverted papilloma (IP) is a rare, benign tumor of the nose and paranasal sinus. However, it is locally aggressive, the recurrence rate is high and malignant transformation is possible. Until now, IP of the hard palate has rarely been reported in the literature. Here, we reported a case with IP of the hard palate, which clinically presented as a carcinomatous growth. The management of IP is complete surgical excision with a close follow-up to detect early recurrence and/or malignant transformation

Introducción: El papiloma invertido es un tumor benigno inusual del tracto nasosinusal, caracterizado por el riesgo de recurrencia y transformación maligna. Objetivo: Nuestro objetivo es describir la serie de casos diagnosticados con papiloma invertido del tracto nasosinusal entre 2002 y 2010. Material y método: Se trata de un análisis retrospectivo de los casos nuevos de papiloma invertido del tracto nasosinusal atendidos en nuestro Hospital entre los años 2002 y 2010. Resultados: Se presentaron 25 casos nuevos de papiloma invertido. Los síntomas tenían en promedio 2 años de evolución, siendo la obstrucción nasal y rinorrea los más frecuentes. La etapificación preoperatoria fue realizada mediante tomografía computarizada en 15 pacientes. El abordaje endoscópico fue el preferido. Cincuenta y seis por ciento de los pacientes correspondía a la etapa 2 de la clasificación de Krause. El promedio de seguimiento fue 29 meses. Durante ese periodo, 4 casos presentaron recurrencia, correspondiendo al 16% de nuestra serie. La mitad de ellos presentó displasia o atipia al momento de la recurrencia. Ocurrió 1 caso de transformación maligna, el cual se presentó como un carcinoma indiferenciado. Conclusión: Las características generales son similares a los reportes internacionales. En nuestro medio los pacientes son diagnosticados en etapas avanzadas de la enfermedad, no obstante, el abordaje endoscópico es el método quirúrgico preferido.

Introduction: Inverted papilloma is an unusual benign tumor of the sinonasal tract, characterized by an important risk of recurrence and malignant transformation. Aim: Our objective is to describe the case series diagnosed with inverted papilloma of the sinonasal tract between the years 2002 and 2010. Material and method: A retrospective analysis of new cases of inverted papilloma of the sinonasal tract treated at our Hospital between the years 2002 and 2010. Results: 25 cases of newly diagnosed inverted papilloma presented in our institution. The symptoms had on average 2 years of evolution, being nasal obstruction and rhinorrhea the most frequent. Preoperative staging by computed tomography (CT) was performed in 15 patients. The endoscopic aproach was preferred as surgical approach. 56% of the patients corresponded to stage 2 of Krause classification. Median folow up was 29 months. During that period, 4 patients had recurrence, corresponding to 16% in our series. Half of these patients had dysplasia or atypia at the time of recurrence. 1 case of malignant transformation ocurred, which presented as an undifferentiated carcinoma. Conclusions: General characteristics were similar to those reported in international reports. In our setting, patients are diagnosed in advanced stages of disease, nevertheless, endoscopic approach is the preferred surgery method.

O papiloma invertido (PI) apresenta diversos tipos de tratamento cirúrgico. A abordagem endoscópica exclusiva tem se mostrado na última década como boa opção em relação à abordagem externa. OBJETIVO: Descrever a amostra dos pacientes com diagnóstico de papiloma invertido, mostrar a experiência do serviço no manejo do tumor e comparar os dados com os da literatura. Forma do Estudo: Estudo de coorte histórica com corte transversal. MÉTODO: Estudo retrospectivo dos prontuários de 17 pacientes operados em um serviço de Rinologia entre 2005 e 2011. Foram avaliados perfil epidemiológico, estadiamento de Krouse, via de acesso cirúrgico, malignização e recorrência pós-operatória e a correlação entre recidivas e estadiamento pré-operatório, via de acesso cirúrgico e malignização. RESULTADOS: Cinco (29,41%) dos pacientes foram classificados como estádio T2 de Krouse, nove (52,94%) como T3 e três (17,65%) como T4. Três (17,65%) pacientes apresentaram malignização e quatro (23,5%) recidiva. Onze pacientes (64,70%) foram submetidos à via endoscópica exclusiva, três (17,6%)à via combinada e três (17,6%) à via aberta. CONCLUSÃO: O acesso endoscópico exclusivo atualmente é um método não só eficaz como também seguro para o tratamento dos estádios mais avançados do PI.

Inverted papilloma (IP) has several treatment avenues. The endoscopic approach in the last decade has proven to be a good option over the traditional approach. OBJECTIVE: Describe the epidemiological profile of patients with inverted Papilloma, describe our experience on managing this tumor and compare our data with the literature. Study Design: Cross-sectional, historical cohort. METHOD: Retrospective study of medical records of 17 patients treated for histopathologicallyconfirmed inverted papilloma between 2005 and 2011. We assessed patients age, gender, tumor side, symptoms, diagnosis, comorbidities and habits, Krouse staging, surgical approach, intraoperative and postoperative, and malignant postoperative recurrence and also the correlation between recurrence with preoperative staging, the surgical approach used, and the presence of malignancy. RESULTS: Five (29.41%) patients were classified as Krouse stage T2, 9 (52.94%) as T3 and 3 (17.65%) as T4. Three (17.65%) patients had malignancy and the recurrence rate was 23.5% (4 pacients). Eleven patients (64.70%) underwent endoscopic approach, 3 (17.6%) the combined aprroach (endoscopic assisted) and 3 (17.6%) external approach. CONCLUSION: The endoscopic approach is currently becoming a method not only effective but also safe for the treatment of more advanced stages of IP.

Papiloma invertido (PI) corresponde a 0,5 por cento-4 por cento dos tumores nasais benignos. A importância está na agressividade local, taxa de recorrência elevada e possibilidade de transformação maligna. O tratamento é controverso, encontrando melhor suporte na cirurgia endoscópica. OBJETIVO: Descrever aspectos clínico-epidemiológicos e tratamento dos casos de PI de um hospital terciário. CASUÍSTICA E MÉTODO: Estudo retrospectivo, realizado por revisão de prontuários de 26 pacientes com diagnóstico de PI nasal, avaliando localização tumoral, estadiamento clínico, tempo de seguimento, recidiva tumoral, malignidade, tipo de cirurgia realizada e complicações pós-operatórias. RESULTADO: Na casuística, havia 13 homens e 13 mulheres, com idade média de 57,8 anos. O tempo médio de seguimento foi de 29,4 meses, com 7,6 por cento de taxa de recidiva. Houve predomínio de tumores T3 e T4 e 3,8 por cento de taxa de malignidade. Todos foram submetidos a tratamento cirúrgico, predominando a cirurgia endoscópica endonasal. CONCLUSÃO: O PI é um tumor nasal originado principalmente na parede lateral nasal, mas também acomete seios paranasais. Avanços na cirurgia endoscópica vêm ganhando destaque pela menor invasividade e taxas de sucesso semelhantes às técnicas tradicionais externas, permitindo a exérese completa do tumor e proporcionando menor taxa de recidiva e tratamento completo no caso de malignidade.

Inverted papilloma (IP) comprises 0.5-4 percent of benign nasal tumors. The importance is shown by local aggressiveness, a high recurrence rate and the possibility of malignant transformation. The treatment is controversial, but endoscopic approaches tends to be the choice today. AIM: To describe clinical, epidemiological and treatment of IP cases in a tertiary hospital. METHODS: Retrospective study consisting of chart reviews of 26 patients diagnosed with IP; evaluation of tumor location, clinical staging, follow up, tumor recurrence, malignancy, type of surgery and postoperative complications. RESULTS: There were 13 men and 13 women, the mean age was 57.8 years. The mean follow up time was 29.4 months; the recurrence rate was 7.6 percent. There was a preponderance of T3 and T4 tumors and a 3.8 percent malignancy rate. All patients underwent surgical treatment, mostly endonasal endoscopic surgery. CONCLUSION: IP is an uncommon nasal tumor that originates mainly in the lateral nasal wall, but it also affects the paranasal sinuses. Advances in endoscopic surgery are gaining room due to lower invasiveness and success rates similar to traditional external techniques for completely resecting the tumor. There is a lower recurrence rate, and endoscopy a definitive treatment for malignancy cases in this study.

Introdução: Papiloma nasossinusal é um tumor benigno com origem no epitélio schneideriano da parede nasal lateral. Sua incidência é rara e de acordo com a literatura responde por 0,5 a 4% de todos os tumores nasais. Objetivo: Reportar a experiência da nossa instituição no tratamento do papiloma nasossinusal invertido utilizando acesso endoscópico e comparar os resultados obtidos com os relatos da literatura. Método: Estudo retrospectivo de todos os pacientes com papiloma nasossinusal que realizaram tratamento cirúrgico puramente endoscópico no ambulatório de Otorrinolaringologia do Hospital das Clínicas da Universidade Federal da Bahia (UFBA), no período de janeiro de 2004 a maio de 2010. Resultados: Um total de 12 pacientes foi incluído neste estudo. O seguimento médio foi de 23 meses. Houve 1 caso de recidiva. Não ocorreu transformação maligna nestes casos. Conclusão: O tratamento do papiloma nasossinusal tem sido amplamente beneficiado com o avanço das técnicas endoscópicas, com taxas de recorrência equivalentes àquelas reportadas por acesso externo. Exames de imagem são fundamentais no planejamento pré-operatório e na decisão da técnica cirúrgica. Um seguimento regular e de longo prazo é essencial para um bom acompanhamento da evolução desta patologia.

Introduction: Sinonasal Papilloma is a benign tumor originating from the epithelium schneiderian lateral nasal wall. Its incidence is rare and according to literature accounts for 0.5 to 4% of all nasal tumors. Objective: To report our institution's experience in the treatment of sinonasal inverted papilloma using endoscopic approach and compare the results with the literature. Methods: A retrospective study of all patients with sinonasal papillomas who underwent a purely endoscopic surgery in the Otorhinolaryngology, Hospital das Clinicas, Federal University of Bahia (UFBA), from January 2004 to May 2010. Results: A total of 12 patients were included in this study. The median follow-up was 23 months. There was one case of recurrence. Malignant transformation has not occurred in these cases. Conclusion: The treatment of sinonasal papilloma has been largely benefited from the advances in endoscopic techniques, with recurrence rates equivalent to those reported for external access. Imaging exams are essential in preoperative planning and the decision of surgical technique. A regular follow-up and long term is essential for a good monitoring of the evolution of this pathology.

O papiloma invertido é um tumor benigno nasal que geralmente se origina na parede lateral da fossa nasal, mais especificamente da região do meato médio. Apresenta grande potencial invasivo local, com alta taxa de recorrência e potencial para transformação maligna. O acometimento do recesso esfenoetmoidal é raro e, quando ocorre, é decorrente de doença primária do seio esfenoidal. Não há relato de papiloma invertido isolado em recesso esfenoetmoidal na literatura. Relatamos um caso de papiloma invertido originado em recesso esfenoetmoidal, sem comprometimento do seio esfenoidal.

Inverted papilloma is a nasal benign tumor that usually arises from the lateral nasal wall, especially from the middle meatus. It has high local invasive likelihood, high recurrence rates and malignancy potential. Sphenoethmoidal recess involvement is rare and is usually due to sphenoid sinus primary disease. In the literature, no case of isolated sphenoethmoidal recess inverted papilloma has been reported yet. The present report describes an exceptional location of inverted papilloma, arising from the sphenoethmoid recess, without involving the sphenoid sinus.

To find the outcome of surgical management of inverted papillomas of the nose and paranasal sinuses. Case series. At Fatima Hospital Baqai Medical University and Usman Memorial Hospital Karachi, from June 2000 to July 2006. A total of 17 cases of inverted papillomas presented to us during the last six years, were managed and the outcome of their surgical treatment was reviewed retrospectively. Out of 17 cases 13 were male and 4 females. All the cases presented with unilateral nasal obstruction. Lateral rhinotomy and medial maxillectomy were the standard surgical procedure adopted for complete excision of the lesion. Two cases had wound infection, one with depressed ipsilateral facial deformity. In two cases recurrence occurred in the post-operative period. Wide surgical excision is the primary treatment modality of inverted papilloma to minimize the incidence of recurrence. Radiation therapy should only be considered in patients with incompletely respectable lesions, multiple recurrent lesions and tumours associated with malignancy

O papiloma invertido nasossinusal é uma neoplasia benigna com potencial de malignização e elevados índices de recidiva pós-operatória. Existe muito debate na literatura a respeito da melhor via de acesso cirúrgico: externa ou endoscópica endonasal. OBJETIVO: Demonstrar a eficácia da via endoscópica endonasal no tratamento do papiloma invertido nasossinusal. FORMA DO ESTUDO: Clínico retrospectivo. CASUíSTICA E MÉTODO: Revisão de prontuário dos pacientes operados por papiloma invertido no HC/FMUSP entre janeiro de 1994 e abril de 2004. RESULTADOS: Vinte e oito pacientes traziam todas as informações estudadas, havendo nove casos de recidiva pós-operatória (32,1 por cento), sendo um caso operado via endoscópica e oito pela via externa. DISCUSSÃO: A classificação proposta por Krouse para estadiamento do papiloma invertido nasossinusal auxilia no planejamento cirúrgico e também permite padronização para comparação de resultados pós-operatórios. A via endoscópica endonasal apresentou menor índice de recidiva tumoral que a via externa ao se comparar casos com o mesmo estadiamento tumoral. CONCLUSÃO: O uso do endoscópio no intra-operatório é uma importante ferramenta para se obter sucesso no tratamento do papiloma invertido nasossinusal.

The inverted papilloma is a benign neoplasm, prone to malignancy, and bearing a high rate of post-op recurrence. There is much debate in the literature concerning the issue that an endoscopic approach may offer a benefit over an external approach. AIM: Demonstrate the efficacy of an endonasal endoscopic approach in the treatment of inverted papilloma. STUDY DESIGN: Retrospective. MATERIALS AND METHODS: Retrospective analysis of patients with inverted papilloma operated at the University Hospital - FMUSP from 1994 to 2004. RESULTS: Twenty-eight patientsÆ records were studied. Nine patients (32.1 percent) had tumor recurrence, one being operated via the endoscopic method and eight by external approach. DISCUSSION: KrouseÆs staging system for inverted papillomas can facilitate both treatment planning and comparison of surgical outcomes. The use of the endoscopic approach resulted in fewer relapses than when the external one was used in cases with the same tumor staging. CONCLUSION: The use of the endoscope in this type of surgical treatment is an important success factor in the treatment of inverted papilloma.
