The aim of this retrospective study was to evaluate the epidemiology, treatment, and complications of frontal bone fractures associated, or not, with other facial fractures. This evaluation also sought to minimize the influence of the surgeon's skills and the preference for any rigid internal fixation system. The files from 3758 patients who attended the Oral and Maxillofacial Surgery Department of the School of Dentistry of Ribeirao Preto, University of Sao Paulo, from March 2004 to November 2011 and presented with facial trauma were scanned, and 52 files were chosen for the review. Eleven (21.15%) of these patients had pure fractures of the frontal bone, and trauma incidence was more prevalent in men (92.3%), whites (61.53%), and adults (50%). Despite the use of helmets at the moment of the trauma, motorcycle crashes were the most common etiological factor (32.69%). Fracture of the anterior wall of the frontal sinus with displacement was the main injury observed (54.9%), and the most common treatment was internal fixation with a plate and screws (45.09%). Postoperative complications were observed in 35.29% of the cases. The therapy applied was effective in handling this type of fracture, and the success rate was comparable to that reported in other published studies.

Osteomas are benign osteogenic lesions that result from the proliferation of mature bone. Three variants are known: central, peripheral, and extraskeletal. The peripheral variant is the most common and it most frequently affects the paranasal sinuses, rarely occurring in the jaws. This article describes the case of a 33-year-old white male patient who was referred complaining of facial asymmetry. Clinical examination revealed an increase in volume at the base of the right side of the mandible, hard bony consistency and well delimited, painless to the touch, without signs of infection or intraoral alterations. Radiographic examination revealed an oval lobulated, radiopaque sessile lesion adhered to the mandibular base near the insertion of the masseter muscle. The patient reported practicing martial arts many years ago. Owing to the limited access, it was decided to perform the complete lesion removal through an extraoral surgical approach, by using a skin crease in the upper neck region below the lesion. The patient recovered well and the histopathological analysis confirmed the diagnosis of osteoma. The etiopathogenesis of osteoma is not completely elucidated, and 3 theories are more accepted: developmental defect, neoplastic nature, and reactive lesion owing to trauma or local infection. The clinicopathological correlation in the present case supports a traumatic origin. Traumatic peripheral osteoma should be considered in the differential diagnosis of nodular bone-forming lesions affecting the mandible.

The treatment protocol yielded suitable post-operative results and also showed success rates comparable to published data around the world.
