A 32-year old man was admitted to the Department of Oral and Maxillofacial Surgery, Busan National University Hospital with complaints of unsightly appearance, inability of chewing and swallowing. The patient had attempted suicide by taking insecticide and persistent muscle contraction for over 2 years has brought collapse of lower arch, open bite deformity and disturbances of mastication and deglutition. After reducing the contraction of muscles by administration of muscle relaxants and tranquilizers, we carried out intraoral sagittal split osteotomy on both rami and suprahyoid myotomy. In this paper, we also reviewed the effects of insecticide poisoning to the nervous system and the dentofacial deformity caused by abnormal muscle forces.
