Abstract

Objective

The purpose of this study was to compare a cohort of developmental dentofacial deformity (DFD) subjects that underwent redo orthognathic surgery (OGS) to a similar cohort who underwent primary OGS. The investigators hypothesized there would be no difference in operative time, blood replacement, perioperative airway risks, length of hospital stay or complication rates.

Study Design

The investigators implemented a retrospective study of subjects with a DFD that were initially treated with orthodontics and jaw osteotomies and later underwent 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

10 subjects met inclusion criteria. The mean age was 31 (range 20-47 years). The operating time was 3:36 ± 47 minutes for redo OGS compared to 2:59 ± 32 minutes for a similar cohort's primary OGS (p < 0.05). All redo subjects had favorable outcomes with reference to the occurrence of lingual nerve injury, "bad" split, infection and need for re-operation. 9/10 subjects achieved and maintained optimal long-term occlusion for all parameters studied.

Conclusion

Subjects that underwent redo OGS required a longer operating time but the remainder of the hospital course and occurrence of major complications was similar to that documented for individuals undergoing primary orthognathic surgery.
