Abstract

PURPOSE: The purpose of this study is to examine the association between type of facial osteotomies performed during orthognathic surgery and postoperative outcomes including complications, length of stay, and readmission. METHODS: A retrospective review of orthognathic surgery cases from the Pediatric Health Information System (PHIS) database from 2004 to 2014 was undertaken. Osteotomy procedures were classified as Le Fort 1 (LF 1), Mandibular osteotomy, Genioplasty or their combinations. Primary outcome variable was major complications. Secondary outcomes included postoperative LOS > 1 day and 90-day readmission. Random-intercept logistic regression models were utilized to assess the association between the type of osteotomy performed and the outcomes. Bonferroni approach was used to account for multiple comparisons. RESULTS: The sample included 5413 patients, with a mean age of 17.1 ± 1.68 years and 60.65% were female. The most common procedures were LF1 (39.4%), followed by bimaxillary surgery (23%). Major complications occurred in 8.57% of patients, postoperative LOS > 1 day in 52.4% and 90-day all-cause readmission in 11.16%. In adjusted analyses comparing LF1 compared to mandibular osteotomies, there were no significant differences for major complications (OR = 0.78), 90-day readmission rate (OR = 0.98). However, LF1 was associated with an increased odds for LOS compared to mandibular osteotomies (OR = 1.42). Addition of osteotomies is associated with a significant increase in LOS (P < 0.001). CONCLUSIONS: Patients undergoing orthognathic surgery demonstrated increased length of stay for LF1 or bimaxillary osteotomies. Osteotomy type did not impact the odds of readmission or complications. The trends revealed should be helpful for patient counseling.
