Transmastoid approach

The transmastoid approach allows better control of the clivus and paraclival regions, however, the supratentorial part of the lesions are out of surgical view 1) 2) 3).

to repair of spontaneous temporal bone cerebrospinal fluid leak is highly successful. Furthermore, patients in the series from Kim et al.,had excellent hearing results with closure of their air-bone gap to ≤12 dB, which has not been previously described 4).

Facial nerve decompression via the transmastoid approach with temporal lobe retraction provides better exposure to the key areas around the geniculate ganglion without complications 5).
