The Impact of the Post-Traumatic Facial Reconstruction on Postoperative Weight Loss.

Objectives

To identify risk factors and evaluate the impact of various facial fractures and reconstruction surgeries on postoperative weight change.

Methods

Retrospective, monocentric study was performed at a tertiary care center. Medical history, type and mechanism of fracture, operative factors, and postoperative weights at follow-up appointments for 145 adult patients undergoing surgical repair for maxillofacial fractures were collected. Further information was obtained on postoperative diet and whether patients received maxillomandibular fixation (MMF). Univariate and multivariate analyses were utilized to evaluate effects of surgical reconstruction after facial trauma on postoperative weight loss.

Results

Patients lost 3.2 ± 4.9 kg (95% confidence interval = 2.7-4.1, P < .0001) on average, with maximum loss between date of surgery and first follow-up. Univariate analysis demonstrated that intensive care unit admission (5.9 kg, SD 5.4, P = .001), nasogastric tube placement (5.1 kg, SD 4.6, P = .012), and MMF (4.4 kg, SD 5.4, P < .0001) were associated with more severe weight loss. Multivariate analyses showed that only MMF remained a significant risk factor for increased weight loss (avg. 6.0, standard error 1.93, t value 3.11, P = .0024).

Conclusions

We report significant weight loss following facial trauma and reconstruction, which emphasizes the need to perform further studies on nutrition protocols for this patient population to optimize wound healing.
