Complications following mandibular fracture repair (MFR) may carry significant morbidity to patients. The purpose of our study is to determine the risk factors for postoperative complications following MFR. The authors conducted a retrospective cohort study of trauma patients who underwent MFR in 2018 and 2019. Excluded were patients below 18 years old and those with postoperative follow-up <2 weeks. The primary outcome was the incidence of major and minor postoperative complications following MFR. Of n=275 patients included, mean (SD) age was 35 (14) years and median (IQR) follow up was 49 (26-117) days. Most patients [n=208 (76%)] underwent both maxillomandibular/intermaxillary fixation (MMF/IMF) and open reduction and internal fixation (ORIF). The incidence of major postoperative complications was 19% (n=51) including malunion [n=8 (2.9%)], malocclusion [n=21 (7.6%)], and unplanned reoperation [n=26 (9.5%)]. The incidence of minor postoperative complications was 61% (n=167). Alcohol use at the time of surgery and greater MISS score were associated with greater odds of major complications [adjusted odds ratio (aOR) 95% CI: 3.4 (1.2-9.0), 1.09 (1.02-1.160), respectively]. Smoking at the time of surgery and moderately (>2 mm) and severely displaced fractures (>4 mm) were associated with greater odds of minor complications [aOR (95% CI): 2.1 (1.04-4.2), 2.7 (1.2-6.4), 2.7 (1.1-6.6), respectively]. Alcohol use, smoking, greater MISS score, and displaced fractures >2 mm were significant risk factors for postoperative complications following MFR. Our findings can help guide informed decision making and surgical planning in patients with mandibular fractures., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 by Mutaz B.

Traumatic brain injury (TBI) is common in up to 50% of patients with facial fractures. Orbital fractures account for 25% of all facial fractures. The authors sought to determine the prevalence and risk factors for TBI in patients undergoing orbital fracture repair (OFR) and assess the impact of TBI on surgical timing. A retrospective review of trauma patients who underwent OFR at a single trauma center from 2015 to 2020 was conducted. Excluded were patients <18 years old and those with unreported GCS on presentation. TBI was defined as GCS <15 or any neurological symptom on presentation. TBI was categorized into mild (GCS=14-15), moderate (GCS=9-13), and severe TBI (GCS=3-8). Our primary and secondary outcomes were the prevalence of TBI on presentation and duration from injury to surgery, respectively. Of the 200 patients analyzed, 99 (49.5%) had concomitant TBI on presentation. The most common neurological symptom on presentation was loss of consciousness [n=80 (40%)]. Patients with TBI were significantly more likely to have an orbital roof [n=11 (11.1%), n=4 (4.0%), P=0.048] and lateral wall fractures [n=25 (25.3%), n=14 (13.9%), P=0.031] compared with patients without TBI. Patients with severe TBI were more likely to have delayed OFR-a significantly greater proportion of patients who had severe TBI had OFR after 60 days of injury compared with those without TBI or with mild TBI [5 (39%), 12 (12%), 4 (5%), P=0.032]. Craniofacial surgeons must suspect and screen for TBI in patients presenting with facial trauma, especially those with orbital roof and lateral wall fractures., Competing Interests: The authors report no conflicts of interest, (Copyright © 2024 by Mutaz B.
