Objectivo: Reportar a experiência dum centro terciário na abordagem diagnóstica, decisão, terapêutica e seguimento dos doentes com schwannoma vestibular esporádico.
Material e Métodos: Estudo retrospetivo dos doentes com schwannoma vestibular esporádico, seguidos no Hospital Egas Moniz entre 2007 e 2021. Foram recolhidos os dados demográficos, clínicos, classificação dos tumores, decisão do tratamento e resultados de 79 doentes e analisados os seguintes outcomes: grau de resseção do tumor; perda auditiva; e grau de paralisia facial.
Resultados: 28% dos doentes operados tiveram uma resseção completa ou quase completa do tumor e 72% uma resseção subtotal. 7 em cada 8 doentes operados por via retrosigmoideia ficaram cofóticos, assim como 2 dos 3 doentes por via da fossa média. Não foi encontrada diferença na prevalência da paralisia facial entre as várias abordagens cirúrgicas.
Conclusão: Esta é uma das maiores séries reportadas a nível nacional. Os outcomes obtidos são semelhantes aos de séries internacionais publicadas.
