Abstract:Objective To improve the diagnosis and treatment of hypoglossal schwannoma. Methods The clinical manifestations, diagnosis and surgical results of 4 patients were reported. The literature was reviewed. Results Typical hemiatrophy of the tongue presented in all 4 patients. Special views of the skull, such as those afforded by tomograms revealed enlargement of the hypoglossal canal. MRI could demonstrated the exact extension of the tumor and its relationship to surrounding structures. The patients were operated on via retrosigmoid, extreme lateral suboccpital and cervical approaches respectively. The tumors were removed totally in three patients, and subtotally in one. Conclusion Hypoglossal schwannoma is extremely rare. It can be classified into intracranial, extracranial, intra and extracranial dumb bell shaped, and intracanalicular types based on its location. Most tumors can be totally removed via proper surgical approach.
Keywords:Hypoglossal nerve  Schwannoma  Diagnosis  Surgery
