SCC of the buccal mucosa is a highly aggressive form of oral cavity cancer, with a tendency to recur locoregionally. Patients with buccal mucosa SCC have a worse stage-for-stage survival rate than do patients with other oral cavity sites.

Recurrent laryngeal nerve injury and hypoparathyroidism complication rates after operations for malignant thyroid disease are statistically higher in this series than complication rates after operations for benign thyroid disease. Overall complication rates are also higher for malignant thyroid disease as compared to benign thyroid disease. Before surgical treatment for malignant thyroid disease, patients should be counseled accordingly.

We present a case in which a 23-year-old male patient diagnosed with nasoseptal chondrosarcoma with anterior cranial fossa extension underwent combined surgical approaches to optimize complete resection of the tumor. Surgery was followed by a 6-month course of proton-beam radiation therapy. Extensive tumors of this type with significant intracranial extension require surgical repair of the anterior fossa floor. We employed a repair technique not previously associated with the resection of these tumors, using a split-calvaria osteoplastic rotational flap. This method provided structural integrity while avoiding the risks associated with the use of free bone grafts and metallic meshes.

Odontogenic keratocysts are odontogenic cysts of the jaw, usually the mandible. We present a recurrent case in the maxilla. Immunohistochemical staining is necessary to distinguish the entity from other cystic lesions of the jaw, and aggressive surgical management is required.
