Schwannoma is a benign neoplasm originating from the neural sheath and occurs most commonly in the soft tissues of the head and neck. Intraosseous schwannoma in the maxillofacial region is extremely rare. The present study reports the case of an intraosseous schwannoma located in the mandibular symphysis of a 27-year-old male patient. The tumor was completely excised, and there has been no evidence of recurrence in the nearly two years since the operation. A review of the related literature is also included.
