Objective: To report the experience of a tertiary center in the diagnostic approach, therapeutic decision and follow-up of patients with sporadic vestibular schwannoma.
Material and Methods: Retrospective study of patients with sporadic vestibular schwannoma followed at Hospital Egas Moniz between 2007 and 2021. Demographic and clinical data, tumor classification, treatment decision and outcomes of 79 patients were collected from clinical records and the following outcomes analyzed: tumor resection; hearing loss; and degree of facial paralysis.
Results: 28% of the operated patients had a total or near-total resection of the tumor and 72% a subtotal resection. In 7 of each 8 retrosigmoid surgeries resulted in cophosis. Same result occurs in 2 of the 3 middle fossa approaches. No difference was found in the prevalence of facial paralysis between the various surgical approaches.
Conclusion: This is one of the largest series reported nationally. The outcomes evaluated are similar to published international series.
