Objective: In this study, 26 patients with fourth ventricle tumors, operated with transvermian approach and diagnosed hsitopatologically between 1996-2006 were analyzed retrospectively.

Materials and Methods: Patients' mean age was 24 years (5-61), 15 of them were male. Whole patients computerized tomography and magnetic resonance imaging were applied preoperative period. Hydrocephalus was detected in all patients, and external ventricle drainages were applied in our department or in the initial hospitals previously in seven patients before the operation. Patients were followed-up with three months interval with magnetic resonance imaging during the follow-up period. The mean of follow-up duration was 19.3 months (change between 12-72 months). All patients were operated with inferior vermian dissection after suboccipitial craniectomy in concorde position.

Results: Postoperative mortality had not occurred. Partial cerebellar excision performed in one patient. Reoperation and ventriculoperitoneal shunt were not required in all patients postoperatively.

Conclusion: Although behavior disorders, mutism, and oropharyngeal apraxia were reported in patients who were operated with transvermian approaches, the classic midline approach with inferior vermian dissection was an efficient, controlled, confortable and a simple method for the fourth ventricle tumors.
