Age and Number of Surgeries Increase Risk for Complications in Polytrauma Patients with Operative Maxillofacial Fractures.

Background: Poly-trauma patients often sustain complex head/neck injuries requiring prolonged hospitalizations and multiple operations. Few studies have evaluated the associated injury patterns and risk factors for poor clinical outcomes.

Methods: Consecutive poly-trauma patients with operative maxillofacial fractures treated at a level 1 trauma medical center between 1995 and 2013 were evaluated. Concomitant head/neck injuries to identify potential injury patterns were numerated. Lastly, a multivariate analysis was performed to determine independent risk factors for complications during the acute hospitalization period.

Results: Totally, 232 poly-trauma patients presented with operative maxillofacial fractures, while 38.8% of patients had a secondary maxillofacial fracture, 16.4% had intracranial hemorrhage, 23.7% had skull fractures, and 12.1% had spinal fractures. The rate of complication during admission was 28.3%. Multivariate analysis revealed advanced patient age and increased number of operations to predict the rate of complication. Patients requiring more than one operation had a 1.8-fold increase in complication rate (<0.01) and older patients had a 4.5% increase in complication rate (<0.05) for every year of increased age.

Conclusion: Poly-trauma patients have a high incidence of secondary maxillofacial fractures, concomitant head/neck injury, and inpatient complication rate. Knowledge of associated injury patterns can help increased awareness and can guide physician decision-making to avoid missed/delayed injuries.
