Vestibular schwannoma approaches

Retrosigmoid transmeatal approach for vestibular schwannoma.

Translabyrinthine approach for vestibular schwannoma.

Middle Fossa Approach

Retrosigmoid transmeatal approach and Translabyrinthine approach (TL) seem similar in terms of resection efficacy. However, according to a analysis, the TL approach is less morbid. Thus, for VS in which hearing preservation is not considered, TL approach is preferable 1).
