Abstract
Hypoglossal schwannoma is a rare skull base neoplasm, which lies in the midst of extremely complex anatomical structures. We report a 39-year-old man who presented with a history of right glossal hemiatrophy, dysesthesia and weakness of the left extremities. These symptoms were caused by a unilateral hypoglossal schwannoma located at the cranial base. This lesion was exposed through a dorsolateral suboccipital transcondylar approach, which was navigated with the frameless stereotaxy (NADOSTA). We also describe the epidemiology, symptomatology and the diagnosis of hypoglossal schwannoma as well as literature review of the operative approach. By introducing this minimally invasive dorsal surgical approach with neuronavigation in treating hypoglossal schwannoma, we believe that safe exposure and complete tumor resection can be achieved with minimal rate of morbidity.
