ABSTRACT
Objective: a review of 20 patients with petroclival tumor who underwent opetratins during 10 years from 1991 to 2001
Methods: in this perospective study 20 patients with petroclival tumor in the skull base underwent operations. Symptoms, signs, pathology, site of lesion extent of tumor complication, complications and mortality were evaluated
Results: patients were 14[70%] females and 6 [30%] males. Patients, ages ranged from 5-60 years with a mean of 36.5 Symptom period ranged from 1-36 months with a mean of 12.3.

Pathology in 8 cases [40%] was meningioma, in 5 cases [25%] was trigeminal schwannoma, in 4 cases [20%] was epidermoid, in 2 cases [10%] was chorodoma, and in one case [5%] was ependymoma. Access to tumor was 100%. Amount of tumor resection was: gross total [45%], subtotal [30%] and partial [25%] eleven people [55%] developed complications and there was 1 case [5%] of mortality
Conclusion: according to the anatiomical position of the petroclival regional varous pathologies, the transpetrosal approach is an acceptable approach. Access to tumor was possible in all cases. Resection of tumor was done in 75% totally or subtotally. There was 5% mortality and 55% complications, was acceptable
