PURPOSE: The purpose of this study was to report the incidence, causes, and patterns of maxillofacial injury associated with domestic violence. PATIENTS AND METHODS: A retrospective review of patients treated for domestic violence injuries at an inner-city hospital over a 5-year period was done, and data were collected on type and location of injury, mechanism of injury, alcohol involvement, and treatment. RESULTS: The sample consisted of 236 emergency room admissions. The majority (81%) of victims presented with maxillofacial injuries. The fist was a favorite means for assaults (67%). The middle third of the face was most commonly involved (69%). Soft tissue injuries were the most common type of injury (61%). Facial fractures were present in 30% of victims. The average number of mandible fractures per patient was 1.32. The majority of facial fractures (40%) were nasal fractures. Left-sided facial injuries were more common than right sided. CONCLUSIONS: These data confirm that most victims of domestic violence sustain maxillofacial injuries. Midface injuries predominate. The preponderance of facial injuries makes it very likely that oral and maxillofacial surgeons will be involved in the care of these patients.

Cementifying fibromas are rare fibro-osseous tumors that arise from the periodontal ligament. These tumors are usually small, asymptomatic lesions noted on routine dental radiography, but they can develop into aggressive, expansile masses. The authors report the case of a 12-year-old boy with a tumor involving the maxillary, ethmoid, and frontal sinuses that extended to the right orbit, causing proptosis and disfigurement of the right side of his face. Removal of the tumor with facial reconstruction resulted in significant improvement of vision, despite long-standing disc edema and tension on the optic nerve. On histopathologic examination the lesion was found to be a cementifying fibroma.
Segmental mandibular resection should be undertaken if there is a demonstrable invasion by cancer or if such invasion is suspected. Before the advent of microvascular free flaps, immediate osseous reconstruction of the anterior mandible was technically demanding and unreliable. Mandibular reconstruction with microvascular free flaps is no longer a novelty, nor is it reserved for unusually large resections. It has become the method of choice for the immediate reconstruction of defects resulting from mandibular cancer. This technique is particularly well-suited for defects of the anterior mandibular arch.

Using the framework of case management, a team partnership was developed for the head and neck surgery population undergoing reconstruction with free tissue transfers ("free flaps"). The focus of the partnership was to improve care coordination from surgery scheduling through discharge. Practice agreements were negotiated, pre-printed on a clinical path, and further supported by pre-printed physician's orders, teaching materials, and a variance tracking tool. In the 6 months since implementing this partnership, patients have recovered more quickly, reducing length of stay by 25% and costs by 15% to 20%.

Maxillofacial trauma frequently is accompanied by significant injuries to the teeth and their supporting structures. This review of these dental injuries relates their management to other priorities of the head and neck trauma patient. The controversy over management of the tooth within the line of a mandibular fracture is discussed.

The transoral approach to open reduction of mandibular fractures has gained popularity but remains controversial. This report reviews 37 consecutive transoral open reductions of various mandibular fractures performed in 32 patients over a 2-year period. The fracture site most often addressed transorally was the symphysis and parasymphysis area. A 19% complication rate and an 11% infection rate were observed.
