Abstract
PURPOSE: In some patients, "surgery first" (SF) may represent a reasonable approach for the expedited correction of a maxillofacial deformity. Based on the prospective evaluation of a large sample, this article provides a specific orthodontic and surgical protocol, discusses the benefits and limitations of this approach, and updates its indications. MATERIALS AND METHODS: Forty-five patients were managed with an SF approach. Selected cases presented symmetrical skeletal malocclusions with no need for extractions or surgically assisted rapid palatal expansion. Periodontal or temporomandibular joint problems and management by an orthodontist without experience in orthognathic surgery were considered exclusion criteria. Virtual treatment planning included a 3-dimensional orthodontic setup. Standard orthognathic osteotomies were followed by buccal interdental corticotomies to amplify the regional acceleratory phenomenon. Miniscrews were placed for postoperative skeletal stabilization. Orthodontic treatment began 2 weeks after surgery. Archwires were changed every 2 to 3 weeks. At 12-month follow-up, patient satisfaction and orthodontist satisfaction were evaluated on a visual analog scale of 1 to 10. Descriptive statistics were computed for all study variables. RESULTS: The studied sample consisted of 27 women and 18 men (mean age, 23.5 yr). The main motivation for treatment was the wish to improve facial esthetics. Bimaxillary surgery was the most common procedure. Mean duration of orthodontic treatment was 37.8 weeks, with an average of 22 orthodontic appointments. Mean patient and orthodontist satisfaction scores were 9.4 (range, 8 to 10) and 9.7 (range, 8 to 10), respectively. CONCLUSIONS: The SF approach significantly shortens total treatment time and is very favorably valued by patients and orthodontists. Nevertheless, careful patient selection, precise treatment planning, and fluent bidirectional feedback between the surgeon and the orthodontist are mandatory.
