Abstract

Abstract : Purpose: Patients with significant dentofacial deformities undergoing aesthetic and functional orthognathic surgery may often require genioplasty to advance the position of the pogonion relative to B point. No study to date has evaluated nationally registered data pertaining to addition of osseous genioplasty to bimaxillary orthognathic surgery and its associated clinical outcomes. Methods: Data was extracted from the National Surgical Quality Improvement Program from 2010 to 2018 using current procedural terminology codes pertaining to Le Fort I osteotomy (LF), bilateral sagittal split osteotomy (BSSO), and osseous genioplasty (G) and divided into 2 cohorts: bimaxillary orthognathic surgery with and without osseous genioplasty. Thirty-day postoperative outcomes inherently recorded within National Surgical Quality Improvement Program were identified and recorded. Chi-squared analysis and unpaired 2-tail t tests were performed between the cohorts and their respective outcomes to determine significant relationships with significance set as P < 0.05. Results: There were 373 patients double- or triple-jaw patients identified from the years 2010 to 2018. The most common recorded indication for LF/BSSO was maxillary hypoplasia (27.3%) and mandibular hypoplasia (6.8%). The most common indications for LF/BSSO/G were maxillary hypoplasia (16.1%) and maxillary asymmetry (16.1%). In comparison to LF/BBSO only, LF/BSSO/GP was not associated with any differences in the rate of surgical (0.0% versus 0.31%, P = 0.72) or medical complications (0.0% versus 0.63%, P = 0.60), in addition to unplanned readmissions (0.0% versus 1.56% versus P = 0.41) or reoperations (0.0% versus 1.25%, P = 0.46). However, osseous genioplasty addition was associated with increased overall operating time (271.77 versus 231.75 minutes, P = 0.04). Conclusions: Osseous genioplasty does not alter short-term, 30-day complication rate when performed with bimaxillary orthognathic surgery. As reoperation rates remained relatively unchanged, it can be inferred that immediate adverse events or patient dissatisfaction were not apparent within 30 days. Although mean operating time is slightly longer, cardiopulmonary resuscitation without medical comorbidity was achieved at the conclusion of the procedure.
