Microsurgical resection of an acoustic neuroma via the translabyrinthine approach
Contributors: H. Jeffrey Kim
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.
