Orthognathic Surgery in Older Patients: Is Age Associated With Perioperative Complications?
Academic Article
Overview
abstract
PURPOSE: The incidence of older patients undergoing orthognathic surgery is increasing. The purpose of this study is to evaluate the association between age and perioperative adverse outcomes in patients undergoing orthognathic surgery. METHODS: This is a retrospective cohort study of patients undergoing orthognathic surgery in the 2011 to 2019 American College of Surgeons National Surgical Quality Improvement Program databases. The primary predictor variable was age group (≥40 or <40 years). The primary outcome variable was adverse outcomes occurring within 30 days of the index operation. Descriptive, bivariate, and Firth logistic regression statistics were utilized to evaluate association between age and adverse outcomes. RESULTS: During the study period, 1,226 patients underwent an orthognathic procedure and 835 subjects were included. Of these subjects, 145 were 40 years or older (17.4%) and 690 were less than 40 years (82.6%). Subjects 40 years or older were more likely to be American Society of Anesthesiologists (ASA) classification II (P ≤ .001), ASA III (P ≤ .001), or diagnosed with obstructive sleep apnea (P ≤ .001). A total of 34 subjects experienced an adverse outcome (4.07%), though there was no significant difference in the incidence of adverse outcomes between age groups (P = .152). In bivariate analysis, hypertension on medication (P = .037), procedure type (P = .001), and segmented Le Fort I osteotomies (P = .039) were associated with adverse outcomes. After controlling for age, hypertension on medication, segmented Le Fort I osteotomies, and diagnosis of obstructive sleep apnea, isolated mandibular osteotomies were the only independent predictors of adverse outcomes (odds ratio 2.64; 95% confidence interval, 1.06 to 7.24; P = .038). Length of stay was 1.38 ± 1.43 days for the 40 years or older group compared to 1.06 ± 1.18 in the <40 group (P = .012). CONCLUSIONS: Despite higher ASA classifications, older patients did not have a significantly greater incidence of perioperative adverse outcomes including airway complications, nor was increased age associated with adverse outcomes in bivariate or multivariate analysis.
