Non-surgical treatment of mandibular deviation: a case report

Background: Mandibular deviation due to premature contact of teeth in crossbite may be associated with facial asymmetry. Aim: To describe the non-surgical treatment of mandibular deviation associated with a marked facial asymmetry. Methods: A 13.5 year-old girl presented with a unilateral posterior crossbite, noticeable facial asymmetry, anterior crossbite and displacement of the mandible on closure. She had no history of head injury or significant medical problems and her parents rejected surgical correction. A removable appliance was used to correct the crossbite followed by fixed appliances to complete treatment. Results: Treatment resulted in a marked improvement in facial symmetry and elimination of the mandibular displacement. Conclusions: Early correction of a functional deviation associated with a unilateral facial asymmetry may avoid the need for surgery. (Aust Orthod J 2010; 26: 201-205)
