The translabyrinthine approach has often been reserved for large acoustic neuromas because it requires less retraction on the cerebellum when compared to the retrosigmoid approach for a similar tumor. However, the translabyrinthine approach is equally useful for smaller tumors, when the patients has no residual ipsilateral hearing. It allows for early visualization of the facial nerve, and thus better protection of this crucial nerve.

Translabyrinthine approach for resection of acoustic neuroma
Acoustic neuroma in patient with no residual ipsilateral hearing
small tumor with usable ipsilateral hearing
N/A
CT of temporal bone
MRI of brain
interal acoustic meatus
facial nerve
vestibulocochlear nerve
brainstem
Advantage: early visualization of facial nerve and better protection
Disadvantage: the approach eliminates any remaining hearing function on the ipsilateral side
