“…3Y6 Therefore, we developed a technique that uses pivoting maxillomandibular distraction osteogenesis and moves the pivot point from the temporomandibular joint to the piriform. 7 The major problem associated with the conventional procedures is the long IMF period. During this period, the patient must be on a liquid diet and is thus subjected to a significant amount of stress.…”

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.

Objective:The goals of treatment for hemifacial microsomia include horizontalization of occlusal plane and acquisition of facial symmetry. Although horizontalization of occlusal plane can be easily achieved, facial symmetry, particularly in relation to mandibular contour, can be difficult to attain. Soft tissue is generally reconstructed to correct facial asymmetry, and no studies have described correction of facial asymmetry through skeletal reconstruction.Case:A 12-year-old girl presented with grade IIb right-sided hemifacial microsomia. She was treated using Nakajima's angle-variable internal distraction (NAVID) system for mandibular body distraction.Results:Following treatment, appropriate facial symmetry was achieved, and the patient was extremely satisfied with the results.Conclusions:Thus, we successfully treated the present patient by our novel method involving distraction osteogenesis. This method was effective and useful for several reasons including; the changes were not accompanied by postoperative tissue absorption, donor sites were not involved, and the treatment outcome could be reevaluated by adjusting distraction while the patient's appearance was being remodeled.
