Congenital defect of the vomer bone: A rare cause of septal perforation

Congenital anomalies of the nasal septum besides septal deviation are very rare, and few cases of congenital defect of the vomer have been reported. We present a case of a 13-year-old boy who had a defect in the posteroinferior aspect of the nasal septum that was discovered incidentally during diagnostic work-up for chronic sinusitis. The patient had no history of maxillofacial trauma, drug abuse and had not previously undergone nasal surgery or cautery for epistaxis, and showed no evidence of systemic inflammatory disease. Based on the patient's history and laboratory findings, the septal defect is thought to be due to a congenital defect of the vomer bone.
