An extracranial hypoglossal schwannoma treated via modified transcervical approach

Hypoglossal schwannomas are very rare. These tumors usually originate intracranially, sometimes extend extracranially. Isolated extracranial tumors extremely rare. Surgical approach of hypoglossal schwannomas are variable and surgeon should choose appropriate method considering location of main tumor. The authors experienced and treated a 55 year-old male patient with an isolated extracranial hypoglossal schwannoma extending into the parapharyngeal space. The tumor was removed successfully through modified transcervical approach. We report this case with relevant review of literature.
