A Case of Contralateral Hypoglossal Nerve Palsy after Peroral Resection of Submandibular Gland

The resection of submandibular gland is usually performed via trascervical, transoral approach. The authors suspected the stenosis of Wharton's duct of 54 years old female patient after transoral removal of submandibular stone and the resection of submandibular gland was decided. Because of cosmetic need, the resection was per-formed transorally. The operation was completed successfully without any injury to unilateral lingual nerve or hypoglossal nerve but contralateral paralysis of hypoglossal nerve was seen. In our knowledge, this is the first report of contralateral hypoglossal nerve palsy during transoral resection of submandibular gland.
