Abstract
LeFort I osteotomy (LF1) and bilateral sagittal split osteotomy (BSSO) have unique operative challenges and inherent anatomic considerations that predispose to certain adverse outcomes, yet their respective complication profiles continue to be debated given conflicting results from single-center investigations. The purpose of this study is to perform a multi-institutional analysis of complications, socioeconomic trends, and financial charges associated with orthognathic surgery. A retrospective cohort study was conducted of orthognathic procedures performed in the United States from 2010 through 2020 using the Pediatric Health Information System. Patients younger than 12 years of age were excluded. Medical complications, surgical complications, and admission costs were compared across procedures. Socioeconomic determinants and trends across regions of the country were also analyzed. During the study interval, 6640 patients underwent orthognathic surgery, including LF1 (59.2%, n=3928), BSSO (14.4%, n=959), and double-jaw surgery (26.4%, n = 1753). Patients undergoing LF1 were more likely to experience overall complications ( P <0.001), infections ( P <0.001), and blood transfusions ( P <0.001) than those undergoing BSSO. High-volume hospitals were more likely to perform double-jaw procedures than other hospitals ( P <0.001), yet high-volume hospitals were less likely to have surgical complications ( P =0.014). Patient admission charges related to orthognathic operations at high-volume hospitals were less than other hospitals ( P <0.001). Household income was higher for orthognathic procedures performed at high-volume hospitals ( P <0.001). White patients were 1.5 times more likely to choose a farther, higher volume hospital for orthognathic surgery than the one locally available ( P =0.041). LeFort I osteotomy procedures had higher infection and transfusion rates than BSSO procedures. High-volume hospitals were more likely to perform double-jaw procedures, yet high-volume hospitals had fewer complications and decreased admission charges. Future study will be needed to further elucidate case-mix index details and socioeconomic determinants of health contributing to these disparities.
