ABSTRACT
High energy trauma has been considered a risk factor for blunt cerebrovascular injuries (BCVI). The purpose of this study was to determine the incidence and risk factors for BCVI specifically in patients with maxillofacial fractures in an urban level I trauma center. A retrospective cohort study of patients aged ≥ 18 years, admitted to Massachusetts General Hospital (MGH) between 2007 and 2017, was implemented. There were 23,394 patients treated and entered into the MGH Trauma Registry: 22,287 sustained blunt trauma. Of the total blunt trauma patients, 68 (0.3%) had BCVI. There were 2421 patients with CMF fractures from blunt trauma (mean ± standard deviation age, 53 ± 22 years; 29.9% female included as study subjects, of whom 24 (1.0%) had BCVI). In a multivariate model, all mandible fracture (odds ratio (OR) 4.3, 95% confidence interval (CI) 1.6-11.6, P = 0.004), crush injury, defined as blunt compression injury (OR 11.1, 95% CI 2.1-58.1, P = 0.004), and cervical spine injury (OR 10.1, 95 CI 3.7-27.5, P < 0.001) were independent risk factors for BCVI. Mortality was 4.3 times higher in craniomaxillofacial fracture patients with BCVI versus those without BCVI; complications of BCVI (stroke) contributed to the majority of deaths. Appropriate screening and treatment of BCVI in patients with maxillofacial fractures is important.

The aim of this retrospective cohort study was to determine the frequency and risk factors for cervical spine injury (CSI) in patients with midface fractures. Patients ≥18 years of age entered in the Massachusetts General Hospital Trauma Registry from 2007 to 2017 were identified. Those with a midface fracture, computed tomography and/or magnetic resonance imaging of the cervical spine, and complete medical records were included. There were 23,394 patients in the registry; 3950 (16.9%) had craniomaxillofacial fractures and 1822 (7.8%) had a CSI. Craniomaxillofacial fractures included fractures of the midface (n=2803, 71.0%), mandible (n=873, 22.1%), and midface plus mandible (n=274, 6.9%). The overall frequency of CSI in patients with midface fractures was 11.4% (350/3077). Patients with midface fractures had a higher risk for CSI compared to patients without a midface fracture (odds ratio 2.4, 95% confidence interval 2.1-2.4, P<0.001). In a multivariate model, nasal and orbital fractures, chest injuries, age, injury severity score, and motor vehicle crash or fall as the etiology were independent risk factors for CSI. Mortality was two times higher in subjects with CSI. Early and accurate diagnosis of CSI is a critical factor when planning the treatment of patients with these fractures.
