The purpose of this study was to compare the functional outcomes of different types of bilateral mandibular condylar fractures. This was a retrospective study of patients with bilateral mandibular condylar fractures at a level-1 trauma center over a 15-year period. The primary predictor variable was fracture pattern, classified as type I (bilateral condylar), type II (condylar–subcondylar), or type III (bilateral subcondylar). Secondary predictor variables were demographic, injury-related, and treatment factors. Bivariate associations between the predictors and complication rates were computed; a multiple logistic regression model was utilized to adjust for confounders and effect modifiers. Thirty-eight subjects with bilateral condylar injuries met the inclusion criteria. The samples mean age was 37.6 + 18.2 years, and 16% were female. The most common mechanisms of injury were motor vehicle collisions (53%) and falls (29%). Seventy-four percent had associated noncondylar mandibular fractures, and 32% of cases had concomitant midface fractures. Fifty-three percent of cases were classified as type I, 21% as type II, and 26% as type III. Ten subjects (26%) were managed with open reduction and internal fixation. The average length of follow-up was 4.5 + 6.3 months. After adjusting for confounders and effect modifiers, the type of fracture was a significant predictor of functional complications with type II injuries having the highest likelihood of a poor functional outcome (odds ratio: 7.77, 95% confidence interval: 1.45–41.53, p = 0.02). Asymmetric bilateral mandibular condylar fractures may be associated with an increased risk of poor functional outcomes.

RESULTS: A total of 46,617 patients with orofacial clefts were identified, 14.6% with isolated cleft lip (CL), 51.7% with cleft lip and palate (CLP), and 33.7% with isolated cleft palate (CP). The incidence of patients requiring EFA increased from 2000 (3.7%) to 2012 (5.8%) (p<0.001). After controlling for comorbidities, the incidence was again found to increase throughout the study period (3.3% to 5.0%, p<0.001). Patients with comorbidities were noted to have higher rates of EFA that increase significantly between 2000 and 2012 (12.8% to 18.6%, p=0.019). Treatment in an urban teaching hospital was an independent risk factor for EFA (OR 4.65). Race and income were not independent risk factors.

Facial skeletal reconstruction of patients with severe Treacher Collins syndrome (TCS) requires correction of both midface and mandibular deficiencies. Implementing virtual surgical planning can provide an accurate three-dimensional analysis of craniofacial abnormalities, creating calvarial donors that match the anatomy of the desired malar augmentation and facilitating bimaxillary movements, positioning, and fixation in orthognathic surgery. We present a case of an 18-year-old patient with TCS, who underwent staged zygomaticomaxillary reconstruction and double-jaw osteotomy with sliding genioplasty, using computer-assisted surgical planning. Following these operations, the patient achieved not only improved facial harmony but also class I occlusion.
