Maxillomandibular tandem osteotomy with distraction osteogenesis for hemifacial microsomia.

Currently, simultaneous maxillomandibular distraction osteogenesis is a standard procedure for the correction of hemifacial microsomia. Many variations of the procedure have been reported. However, a common problem has been the extended duration of the procedure. In particular, the lengthy intermaxillary fixation period includes a prolonged distraction series that requires the restriction of oral food intake and creates significant stress for the patient, which has a profound effect on patient satisfaction. To avoid this stress, we have developed tandem osteotomy with distraction osteogenesis, termed the TODO procedure. The TODO procedure not only shortens the intermaxillary fixation period and the duration of therapy but also creates the ideal skeletal proportions, with horizontalization of the occlusal plane. The TODO procedure has the added benefit of producing a marked aesthetic improvement. The patient was extremely satisfied by the result and endured minimal stress.
