Risk Factors for Acute Postoperative Complications Following Operative Management of Le Fort Fractures-A NSQIP Study.

INTRODUCTION: Le Fort fractures comprise a pattern of complex midfacial fractures that arise secondarily to craniofacial trauma. Although management of these fractures has been detailed within the literature, there is a paucity of research examining postoperative outcomes after surgical repair. The primary aim of this study is to assess patient outcomes after operative management of Le Fort fractures, and examine factors influencing the risk for developing postoperative complications, through utilization of the ACS-NSQIP database.

METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for cases recorded between 2012 and 2019 with International Classification of Disease (ICD)-9 and ICD-10 codes corresponding to Le Fort fractures. Patient demographics, clinical variables, and postoperative variables were recorded. Logistic regression analysis was conducted to identify independent risk factors for postoperative complications.

RESULTS: Identification of cases with appropriate ICD codes, and exclusion of those with missing data, yielded 562 patients for analysis. There were no cases of minor complications and 14 cases of severe complications (3 cases of wound dehiscence, 3 cases of transfusion requirement, 1 case of failure to wean from the ventilator for more than 48 h, 1 pulmonary embolism, and 8 cases of reoperation), corresponding to an overall complication rate of 2.49%. Logistic regression analysis revealed steroid use as an independent predictor of severe postoperative complications (OR =13.73, 95% CI: 1.08-128.02, P=0.02).

CONCLUSION: The present study is the first to conduct a risk factor analysis of patients with Le Fort fractures using the ACS-NSQIP national database. The overall postoperative complication rate was 2.49%, with 14 cases of complications recorded in 8 years. Although this may suggest that surgical management of Le Fort fractures is generally well-tolerated, it should be noted that this problem is frequently associated with other severe injuries of the head and neck that may influence patient prognosis. Given this, further analysis would benefit from a larger patient cohort and longer postoperative data as the ACS-NSQIP database only records outcomes within 30 days.
