ObjectiveThe objective of this study is to examine hospitalization outcomes following orthognathic surgeries. This study tests the hypothesis that those with craniofacial anomalies have higher billed hospital charges, longer length of stay, and increased odds for developing infectious complications when compared to those without craniofacial anomalies.MethodsThe Nationwide Inpatient Sample for the years 2012 and 2013 was used. All patients that underwent an orthognathic surgery were selected. The primary independent variable of interest was presence of a congenital cleft/craniofacial anomaly. The outcome variables were occurrence of complications, billed hospital charges, and length of stay. Multivariable logistic and linear regression models were used to examine the effect of a presence of craniofacial anomaly on outcomes.ResultsDuring the study period, a total of 16,515 patients underwent an orthognathic surgery in the United States. Of these, 2,760 patients had a cleft/craniofacial anomaly. 7.4% of those with a craniofacial anomaly had an infectious complication (compared to 0.6% in those without a craniofacial anomaly). The mean billed hospital charges in those with a craniofacial anomaly was $139,317 (compared to $56,189 in those without a craniofacial anomaly). The mean length of stay in hospital in those with craniofacial anomaly was 8.8 days (compared to 1.8 days in those without a craniofacial anomaly). These differences in outcomes between those with and without a craniofacial anomaly were significant after adjusting for patient and hospital level confounders.ConclusionsThose with a craniofacial anomaly are at a higher risk for developing infectious complications, have higher hospital charges, and stay in hospital for a longer duration of time following an orthognathic surgery when compared to those without a craniofacial anomaly.
