Temporomandibular dysfunction in patients treated with orthodontics in combination with orthognathic surgery.
Fifty-two patients with malocclusions underwent orthodontic treatment in combination with orthognathic surgery involving a Le Fort I and/or sagittal split osteotomy. Approximately 5 years after surgery, the patients were examined for signs and symptoms of temporomandibular disorders (TMD). The frequencies were found to be low in comparison with epidemiological studies in this field. The aesthetic outcome and chewing ability were improved in most patients (about 80 per cent). Some of the patients had reported recurrent and daily headaches before treatment. At examination, only two patients had reported having a headache once or twice a week, while all the others suffered from headaches less often or had no headache at all. Eighty-three per cent of the patients reported that they would be prepared to undergo the orthodontic/surgical treatment again with their present knowledge of the procedure. This study shows that orthodontic/surgical treatment of malocclusions not only has a beneficial effect on the aesthetic appearance and chewing ability, but also results in an improvement in signs and symptoms of TMD, including headaches.
