Injury Patterns and Physiologic Risk Stratification in Facial Trauma Patients with Orbital Fractures: A National...

Area of Science:

• Trauma Surgery
• Ophthalmology
• Emergency Medicine

Background:

• Orbital fractures are frequent in trauma care.
• Age-specific injury mechanisms and risk stratification are not well-defined.
• This study addresses these gaps in understanding.

Purpose of the Study:

• To identify age-mechanism interaction patterns in orbital fractures.
• To develop an admission-based physiological risk score for orbital fracture patients.
• To stratify risk for better resource allocation and patient outcomes.

Main Methods:

• Retrospective analysis of 41,464 adult orbital fracture patients (2018-2020).
• Development of a three-component physiological risk score (hypotension, tachycardia, GCS).
• Validation of the risk score against adverse outcomes.

Main Results:

• Elderly patients (≥65) primarily sustained falls; young adults showed bimodal patterns (crashes, violence).
• Violence-related injuries in younger patients had lower severity and mortality than accidental mechanisms.
• The physiological risk score demonstrated strong predictive performance (AUC 0.79).

Conclusions:

• Distinct age-mechanism patterns exist, with young adults exhibiting bimodal injury causes.
• Admission physiological parameters identify a high-risk group (8.4%) needing intensive care.
• Violence-related orbital fractures had better outcomes than accidental ones, contrary to expectations.
