A surdez súbita é um sintoma cuja etiologia nem sempre é elucidada mesmo dispondo-se de toda propedêutica atual. Neste estudo avaliaremos as alterações encontradas em ressonância magnética de pacientes portadores de surdez súbita. FORMA DE ESTUDO: coorte transversal. MATERIAL E MÉTODO: Estudo prospectivo com realização de RM em 49 dos 61 pacientes com surdez súbita atendidos no pronto socorro de Otorrinolaringologia do Hospital São Paulo, no período de abril de 2001 a maio de 2003. Doze pacientes abandonaram ou não foram submetidos à ressonância magnética por outros motivos. RESULTADOS: 23 (46,9 por cento) pacientes apresentaram alterações à ressonância magnética. Foram encontrados dois tumores sugestivos de meningioma e três schwannomas do oitavo par craniano. Lesões subcorticais e periventriculares esparsas e hiperintensas em FLAIR foram encontradas em 13 pacientes. Cinco (21,7 por cento) pacientes apresentaram alterações periféricas. CONCLUSÃO: A surdez súbita deve ser abordada como um sintoma comum a diferentes doenças. A presença de tumores do ângulo pontocerebelar em 10,2 por cento dos nossos casos, entre outras causas tratáveis, justifica o uso da ressonância magnética com contraste tanto para o estudo do sistema auditivo periférico quanto para o estudo das vias auditivas centrais, incluindo o cérebro.

Se presentan 7 pacientes de cáncer de oído externo y medio. El diagnóstico histopatológico fue carcinoma basocelular (4), espinocelular (2) y carcinoma adenoideoquístico (1). El tratamiento primario en 6 pacientes fue la cirugía. La decisión terapéutica y el tipo de operación se adecuó según los hallazgos intraoperatorios. La resección quirúrgica se efectuó paso a paso dependiendo de la extensión tumoral. Tres de estos pacientes recibieron radioterapia complementaria. Un paciente fue tratado solamente con radioterapia (infiltración de la piel por leucemia linfocítica crónica y presencia de tumores basocelulares múltiples). La sobrevida promedio fue de 31,6 meses con una mediana de 23 meses (3 a 81 meses) y la mortalidad de 28.5 por ciento (un caso confirmado y uno presunto)

Seventy patients with polypoidal lesions were tested to detect affection of Chorda-tympani nerve by an electric taste threshold method. Taste threshold was found to be impaired in 18 patients [25.7%]. Subsequently the patients were classified into three groups, by their histopathological criteria, [a] non-neoplastic group [inflammatory polypi], [b] benign neoplasm group, and [c] malignant tumour group. Six of the 55 patients of non-neoplastic polyp group had raised taste threshold. In benign neoplasm group, four out of seven patients had variable degree of taste sensation impairment. In malignant group, all of the patients had more or less severe degree of loss of taste sensation. Thus the present study indicates that impairment for taste threshold on the side of the lesion is a sign of destructive process or compression. It is concluded that in each case of chronic suppurative otitis media with polypoidal or tumourous lesion, taste threshold should be determined. The patients with impairment of taste sensation should be attended first to prevent severe degree of morbidity
