The use of mandibular body distraction in hemifacial microsomia.

Sakamoto Y, Nakajima H, Ogata H, Kishi K - Ann Maxillofac Surg (2013)

Bottom Line: Soft tissue is generally reconstructed to correct facial asymmetry, and no studies have described correction of facial asymmetry through skeletal reconstruction.She was treated using Nakajima's angle-variable internal distraction (NAVID) system for mandibular body distraction.Thus, we successfully treated the present patient by our novel method involving distraction osteogenesis.

ABSTRACT

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.
