title: An audit on orthognathic surgery: a single surgeon's experience.
abstract: The aim of this article was to present a retrospective audit on a single surgeon's experience with orthognathic surgery. This was a retrospective review of orthognathic cases performed from January 1, 2000, to January 1, 2006. There were 37 male and 65 female patients with a mean age of 20 years. Predisposing conditions included: unilateral cleft lip and palate (40), bilateral cleft lip and palate (15), cleft palate (three), hemifacial microsomia (three), posttraumatic (three), fibrous dysplasia (one), Romberg's disease (one), cavernous hemangioma (one), Crouzon's syndrome (one), and developmental deformities (34: 13 prognathism, 12 class III, six class II, three vertical maxillary excess). Indications for surgery included: class III malocclusion (89), class II malocclusion (six), facial asymmetry (three), vertical maxillary excess (three), crossbite (one). The majority of surgeries performed were Le Fort I osteotomy alone (33) and bimaxillary osteotomy (32). Overall median duration for all surgery was 2 hours 45 minutes (range, 1 hour 15 minutes to 8 hours 45 minutes), median blood loss was 720 mL (range, 100-6500 mL), and mean hospitalization stay was 4.3 days (range, 1-10 days). The mean duration of follow up was 24 months. Postoperatively, class I occlusion was obtained in 92 patients and class II occlusion in two patients. Relapse occurred in five (4.9%) patients (one had reoperation). Readjustment was done for three patients. Excessive bleeding occurred from the facial artery, maxillary artery, and pterygoid plexus separately in three patients. Readmission for secondary hemorrhage occurred twice and inferior alveolar nerve injury occurred once.
