Key Points

To evaluate microsurgical outcomes in patients with medial sporadic vestibular schwannoma.
Matched cohort design involving 40 cases of medial vestibular schwannoma and 120 referents.
Comparison of surgical outcomes like extent of resection, facial nerve function, and hearing preservation.
Analysis of the impact of internal auditory canal (IAC) extension on outcomes.
No statistically significant differences found in extent of resection between groups.
Facial nerve function preservation was comparable regardless of IAC extension.
Hearing preservation rates did not vary significantly based on IAC involvement.

Abstract

In this matched cohort study of medial VS, we found no statistically significant differences in the extent of resection, facial nerve function, or hearing preservation between tumors with and without IAC extension.
