From July 1998 to December 2002, 42 patients (including 29 patients who had undergone radiation therapy) underwent a newly designed lateral nasal wall mucoperiosteal flap pedicled anteriorly on the lateral nasal artery of the angular artery to resurface a translocated facial bone segment during a facial translocation approach to the skull base to prevent its avascular necrosis. Of the 42 patients studied, 1 patient had full-thickness flap loss that resulted in bone graft necrosis. Another patient had marginal necrosis. The average length, width, and surface area of the flap was 30 mm, 45 mm, and 1350 mm measured on 5 patients. The mucoperiosteal flap tolerated radiation therapy well. The lateral nasal wall mucoperiosteal flap is a simple, reliable flap that provides ample vascularized tissue to resurface the nude translocated facial bone segment during a facial translocation approach to the skull base. It thus prevents its avascular necrosis even after radiation therapy.

OBJECTIVE: Patients sustaining facial fractures are at risk for accompanying traumatic intracranial hematomas, which are a major cause of morbidity and mortality. Prompt recognition is crucial in improving patient survival and recovery. This study examined which simple clinical signs identify facial fracture patients at risk for intracranial hemorrhage before the performance of computed tomography. DESIGN AND METHODS: Retrospective study of 2,195 patients with facial fractures during a period of 7 years. By means of univariate and multivariate analysis clinical features potentially predictive for (a) intracranial hemorrhage and (b) surgery for intracranial hemorrhage were identified. SETTING: Critical care units of anesthesiology and neurology, general traumatology, and oral and maxillofacial surgery in a level I trauma university hospital. RESULTS: Seizures (OR 22.1) and vomiting/nausea (OR 20.2) were the strongest independent predictors of intracranial bleeding in facial fracture patients. For intracranial hemorrhages requiring surgical intervention closed head injuries (OR 9.75) and cranial vault fractures (OR 5.0) were the most significant risk factors. However, among those patients without vomiting/nausea and without seizures and without closed head injury ( n=1,628), 20 patients (1.2%) suffered intracranial hemorrhage, and six (0.37%) of them required surgical intervention. CONCLUSIONS: Simple clinical symptoms, such as seizures, vomiting/nausea, history of a closed head injury or cranial vault fractures are strong predictors for intracranial hemorrhage in facial fracture patients. The early consideration of such important indicators allows us to detect patients at elevated risk of an intracranial hematoma requiring surgical intervention.
