Posterior transpetrosal approach

The posterior transpetrosal approaches include the retrolabyrinthine, translabyrinthine, and transcochlear.

The posterior approaches are based on the standard mastoidectomy and involve resection of the petrous bone to various degrees. This results in progressively increased exposure anteriorly, but comes at the expense of hearing in the translabyrinthine approach and of hearing and facial strength in the transcochlear approach.
