ABSTRACT

Objective Several surgical procedures are available for treatment the prominent mandibular angle. But in some patients, only one procedure is not likely to obtain satisfactory results. This study was to evaluate the effect of curved osteotomy combined with sagittal splitting osteotomy of the mandibular angle by an intraoral approach for treatment the broad lower face. Methods 21 patients with broad lower face were treated with mandibular angle osteotomy plus mandibular angle splitting osteotomy under general aesthesia by intraoral approach. Changes of the distance between the mandibular angles were observed during follow up phase. Questionnaires were used to assess the patents level of satisfaction after operation. Results All the wounds healed without complications of bleeding and infection. After 7 months to 12 months follow up, the distance between the mandibular angles was effectively reduced, the deformity of broad lower face were improved markedly, the curve of the mandibular angle was smooth and the shape was natural. Conclusion This method is worthy to be applied widely because of the good result with effective reduction of the width of the lower face, smooth and gentle outline of the face.
