ABSTRACT
INTRODUCTION:
The maxillo-mandibulary dysphormias are frequently associated with morphological abnormalities of the chin. Their correction in the sagittal and transverse planes can benefit both morphologically and functionally. The purpose of this study was to evaluate the morphological benefit of the osseous genioplasty associated with orthognathic surgery depending on the type of technique used, as well as complications occurred. PATIENTS ANDMETHODS:
We identified patients who underwent osseous genioplasty associated with orthognathic surgery in our department between 2004 and 2010. For each patient Angle class, type of osteotomy, genioplasty and postoperative complications were recorded. The morphological results were evaluated by a group of surgeons and a group of observers using standardized photographs.RESULTS:
Of the 203 facial osteotomies performed during this period, 101 osseous genioplasties were made. In most cases, there was a height reduction associated with advancement of the chin. The morphological results were considered as satisfactory all evaluators alike (3.92). The best results were obtained in height reductions with advancement techniques as sliding genioplasty (4.03) and jumping divided genioplasty (4.19). Five patients (5.9%) had a postoperative complication. This was especially one mental nerve injury and two dental mortifications. No default of consolidation or necrosis or hematoma of mouth floor have been reported.CONCLUSION:
Osseous genioplasty is a safe, reliable procedure with morphological satisfactory outcome, in combination with orthognathic surgery. The best results were obtained with cases of height reduction with advancement of the chin, especially the original technique of the jumping divided genioplasty.Palavras-chave
