Abstract

Various treatment strategies have been proposed to perform the aesthetic surgical correction of asymmetric deformities of the mandible. These techniques range from relatively simple to complex procedures including bimaxillary surgery associated with complex mandibular osteotomies. The authors describe a patient with grade III Goldenhar syndrome, treated by a "chin wing" mentoplasty as described by Triaca. These situations are classically treated with a bilateral sagittal splint osteotomy (BSSO) in combination with mentoplasty. However, because of a good occlusion with Angle's class I relation, slight imbalance of the occlusal plane with good function of the mouth opening, the patient refused to be treated with a BSSO, hence, a chin wing mentoplasty was performed. Size and stability of bone regeneration were evaluated by histological examination and dynamic-volume computed tomography (CT). Mature bone in the grafted areas was detected by histology and CT scan with stable results and a significant increase of facial aesthetics 1 year after surgery. The authors also demonstrated that the chin wing technique provided a little but significant breathing improvement as detected on CT scans and lateral X-ray cephalograms by measuring the breathing area. Chin wing mentoplasty is a moderately invasive technique that is able to improve the aesthetics of the face and patient breathing.
