Posterior petrosectomy is subdivided into three variations; retrolabyrinthine technique (petrous bone resection with preversation of hearing), translabyrinthine technique (greater petrous bone resection and sacrifice of hearing), and transcochlear technique (maximal petrous drilling and sacrifice of hearing with transposition of the facial nerve). While 7 out of 14 cases were operated by trans-labyrinthine technique, in other 7 cases retrolabyrintine intervention was used. Patients' ages ranged from 17 to 67 years (mean age 42,2 years), with 7 male and 7 female patients. Histopathological diagnoses were as follows; petroclival meningioma in four cases, petrous bone epidermoid tumor in two cases, outer auricular tumor in three cases, acustic neuroma in one case, plasmocytoma in one case, brains tern glioma in one case and medulloblastoma in one case.
