Juvenile temporomandibular bony ankylosis may generate micro- and retroposition of the mandible. Collapse of the upper airway during sleep due to muscle atonia awakens the patient, leading to compensative diurnal hypersomnia. In severe cases, alveolar hypoventilation may result in anoxic seizure, sudden death or development of life threatening cor pulmonale. The corrective surgical procedure for adult is an anterior sagittal osteotomy and in the growing child, costochondral grafting is proposed. Pre and post operative polysomnograms with recording of oxygen saturation are objective measures of good surgical results.
