Schwannoma arising from hypoglossal nerve in the submandibular triangle: a case report.

ABSTRACT

Hypoglossal schwannomas usually develop in the intracranial portion of the brain. The incidence of hypoglossal schwannomas of the submandibular region is extremely rare. Here we report a case of schwannoma arising from the extracranial hypoglossal nerve in the left submandibular region.
