Hypoglossal neurinoma is vary rare cranial base neoplasm. With the recent advances
in the neuroimaging and surgical technique surgical resection is amenable. A case of
hypoglossal neurinoma which is located ventral to the medulla is reported. The patient
was presented with right hypoglossal nerve palsy, glossal hemiatrophy, and decreased
gag reflex on the right side. Magnetic resonance imaging(MRI) revealed an ovoid mass
ventral to the medulla with enlarged hypoglossal canal. Because of the ventral location
of the mass, far lateral transcondylar approach was selected to minimize the
postoperative morbidity. Radical total resection was achieved. This report describes that
far lateral transcondylar approach is better than conventional suboccipital approach in
regards to satisfactory exposure of the hypoglossal canal and prevention ol excessive
retraction of the neuraxis.
