Redo orthognathic surgery: a report of 10 cases.

OBJECTIVE: The purpose of this study was to compare a cohort of patients who had a developmental dentofacial deformity (DFD) and then underwent redo orthognathic surgery (OGS) to a similar cohort who underwent primary OGS. We hypothesized that there would be no difference in operative time, blood replacement, perioperative airway risks, length of hospital stay, or complication rates. STUDY DESIGN: We implemented a retrospective study of patients with a DFD initially treated with orthodontics and jaw osteotomies and later with redo OGS. The predictor variables were demographic, anatomic, and operative. The primary outcome variables were hospital course and complications. Descriptive and bivariate statistics were computed. RESULTS: Ten patients met inclusion criteria. The mean age at redo OGS was 31 (range 20-47 years). The operating time was 3:36 ± 47 minutes for redo OGS compared with 2:59 ± 32 minutes for a similar cohort's primary OGS (P < .05). All redo patients had favorable outcomes with reference to the occurrence of lingual nerve injury, "bad" split, infection, and need for reoperation. Of the 10 patients, 9 achieved and maintained optimal long-term occlusion for all parameters studied. CONCLUSIONS: Patients who underwent redo OGS required a longer operating time, but the remainder of the hospital course and occurrence of major complications were similar to those documented for individuals undergoing primary orthognathic surgery.
