Abstract

              Most of skull base tumors are conventionally approached by skull base technique. During a two-year period (1998-1999), seven skull base tumors comprised of 6 petroclival tumors and one anterior foramen magnum tumor were operated by a two-staged keyhole approach at Prasat Neurological Institute, Bangkok, Thailand. The patients' age range was 6-75 years. They were 5 males and 2 females. Total tumor removal was achieved in 4 cases. All patients except one which preoperatively bed ridden, showed improvement their neurological functions. There was no mortality except some morbidities; 2 brainstem ischemia which persisted in 1 case, 1 transient cranial nerve III deficit, and 1 cranial nerve V dysfunction that caused facial numbness. This 2-staged keyhole approach is an alternative approach for some skull base tumors and is a minimally invasive technique comparing to other approaches.
