The Characteristics and Cost of Le Fort Fractures: A Review of 519 Cases From a Nationwide Sample.

Purpose: The aims were to report the characteristics of Le Fort fractures and to quantify the associated hospital costs.

Materials And Methods: From October 2015 to December 2016, the National Inpatient Sample was searched for patients admitted with a primary diagnosis of a Le Fort fracture. Predictor variables were drawn from demographic, admission, and injury characteristics. The outcome variable was hospital cost. Summary statistics were calculated and compared among Le Fort patterns. Univariate comparisons and multivariate regression analyses were conducted to determine predictors associated with cost.

Results: A total of 519 patients were identified in this cohort. Associated injuries included skull fractures (28%), intracranial hemorrhage (13%), cervical spine injury (9.8%), and concussion (9.1%). Seventy-three percent of patients received open reduction and internal fixation (ORIF) for their facial fractures during their admission, 13% received a tracheostomy, and 10% were mechanically ventilated for at least 1 day. The ventilation (P < .01) and tracheostomy (P < .01) rates increased with Le Fort complexity, as did length of stay (LOS; P < .01), costs (P < .01), and charges (P < .01). The mean costs of treating Le Fort I, II, and III fractures were $25,836, $28,415, and $47,333, respectively. Increased cost was independently associated with younger age, male gender, African-American ethnicity, Le Fort II and III patterns, motor vehicle accident etiology, mechanical ventilation requirement, tracheostomy, ORIF, transfer to an outside facility, and increased LOS.

Conclusions: The prevalence of head injuries and the need for respiratory support substantially increased with Le Fort complexity. Hospital costs were not markedly influenced by the diagnosis and management of associated injuries. Instead, costs were predominantly driven by fracture complexity and the need for necessary procedures, such as ORIF, tracheostomy, and mechanical ventilation.
