Tumors of the nasal cavity and paranasal sinuses are unusual pathologies found in clinical practice. Approximately 0.8% of all human cancers are located in this area. Despite being rare, nasosinusal neoplasms usually manifest through nonspecific symptoms that are common to numerous inflammatory pathologies. The aim of this study is to describe a series of rare nasosinusal tumors, including esthesioneuroblastomas, central giant cell granulomas, extramedullary plasmocytomas, nasosinusal hemangiopericytomas, neurofibromas and cemento-ossifying fibromas, diagnosed at the Fortaleza General Hospital. We, hereby, briefly review each of the aforementioned pathologies, stressing the need for a precise histological diagnosis for proper treatment in each case.
O nasoangiofibroma é um tumor benigno com componente vascular que acomete homens jovens, e tem como principal tratamento a cirurgia. Tem sido descrita a utilização de cirurgia endoscópica para a ressecção de tumores em estádios iniciais, sem evidência de permanência de restos tumorais ou recidiva da doença. OBJETIVO: Este estudo tem o objetivo de avaliar a via endoscópica precedida pela embolização como meio de tratamento para nasoangiofibroma em estádios II, e um caso selecionado em estádio III, com avaliação da morbidade pós-operatória a partir das seguintes variáveis: tempo cirúrgico, tempo de internamento pós-operatório, necessidade de transfusão sangüínea, presença de complicações, tempo entre embolização e cirurgia e presença de recidiva tumoral. MATERIAIS E MÉTODOS: Foi realizado em estudo prospectivo, a partir de nove pacientes internados no Hospital Geral de Fortaleza SESA/SUS no período de outubro de 2001 a novembro de 2004. CONCLUSÃO: Pelos dados obtidos, concluiu-se que a via endoscópica, quando precedida pela embolização tumoral, é uma via eficaz no tratamento de nasoangiofibromas em estádios iniciais, com reduzida morbidade pós-operatória.
Common surgical approaches for medial maxillectomy include lateral rhinotomy and midfacial degloving. Lateral rhinotomy provides excellent surgical exposure but leaves a bulging scar on the face. Despite its own limitations, midfacial degloving has been preferred to lateral rhinotomy because it does not leave any external scar on the face¹. The aim of this study is to evaluate the cosmetic results and surgical exposure access of midfacial degloving. Treatment morbidity was evaluated through: post operative hospital stay length, blood transfusion needs, complications, pre and post operative hemoglobin levels, disease recurrence, nasal packing, type of suture and antibiotics. Retrospective study was carried out with sixteen patients treated at the Hospital Geral de Fortaleza SESA/SUS from December 1999 through November 2003. Based on the results, we may conclude that midfacial degloving is effective to treat extensive nasal cavity lesions and paranasal sinuses with reduced post operative morbidity.
