Anatomical aspects and technical note of a modified retropharyngeal approach and reconstruction of the anterior occipitocervical junction.

Surgery to expose the anterior occiptocervical junction (OCJ) is exacting, and optimal approaches are debatable. The close proximity of vital structures and difficult surgical access present a unique challenge to treat lesions in this area. Routine access to the upper anterior cervical spine remains limited.

Giant Peripheral Temporomandibular Osteoma With Immediate Reconstruction of Mandible.

Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells.

Assessment of the Postoperative Stability of Mandibular Orthognathic Surgery for Correction of Class III Skeletal Malocclusion.

To assess the stability of mandible position after orthognathic surgery for correction of class III skeletal malocclusion. Twenty adult males, aged 18 to 40 years, with Angle class III skeletal malocclusion underwent preoperative orthodontic treatment for elimination of dental compensations followed by combined maxillomandibular surgery with rigid internal fixation. Lateral cephalograms from each patient, obtained in the natural head position before surgery, immediately after surgery, and at 6-month follow-up, were retrieved from the files of the Pontifical Catholic University of Rio Grande do Sul outpatient Oral and Maxillofacial Surgery clinic and compared.
