[Show abstract][Hide abstract] ABSTRACT: The association between fibrous dysplasia (FD) and fractures is very rare. This paper reports the case of a zygomaticomaxillary complex fracture in a bone affected by FD, a 29-year-old man who was involved in a bicycle accident and who subsequently presented with a zygomaticomaxillary complex fracture. Computed tomography revealed multiple fractures of the left zygomaticomaxillary complex with dysplastic bone alterations. Fracture lines occurred near transitional areas between the lesion and healthy bone. The patient was treated through an intraoral approach by an open reduction and internal fixation procedure, using a titanium miniplate and screws. An incisional biopsy was performed through the maxillary sinus to confirm the diagnosis of FD. After 12 months of follow-up, there were no postoperative complications. This paper reports a rare association thought to be caused by irregular trabecular bone deposition, which increases bone thickness/resiliency and thus increases its clinical fracture resistance.

[Show abstract][Hide abstract] ABSTRACT: Surgically assisted rapid maxillary expansion (SARME) is an effective and stable method for treating severe maxillary transverse discrepancies in skeletally mature individuals, but it has potential complications. The authors report the case of a 34-year-old woman who developed carotid cavernous fistula after undergoing SARME with a bone anchored appliance and discuss the possible etiological basis of this condition.

[Show abstract][Hide abstract] ABSTRACT: Pathologic fractures may occur when a bone has been weakened by an underlying pathologic process. The treatment depends on the etiology. We report on a patient with pathologic fracture in the jaw caused by unicystic ameloblastoma. The lesion was subjected to marsupialization, and the size of the radiolucent lesion decreased. The fracture was consolidated by bone regeneration. For the remaining tumor, a secondary surgery was performed with enucleation followed by spray cryosurgery using a combination of propane, butane, and isobutane gases. The patient showed no signs of recurrence during the 3-year period after the second surgical procedure.

[Show abstract][Hide abstract] ABSTRACT: Central giant cell lesions are benign intraosseous proliferative lesions that have considerable local aggressiveness. Nonsurgical treatment methods, such as intralesional corticosteroid injections, systemic calcitonin and interferon have been reported. Recently, bisphosphonates have been used to treat central giant cell lesions. A case of a 36-year-old male with a central giant cell lesion crossing the mandibular midline was treated with intralesional corticosteroids combined with alendronate sodium for the control of systemic bone resorption. The steroid injections and the use of bisphosphonates were stopped after seven months when further needle penetration into the lesion was not possible due to new bone formation. After two years, the bony architecture was near normal, and only minimal radiolucency was present around the root apices of the involved teeth. The patient was followed up for four years, and panoramic radiography showed areas of new bone formation. Thus far, neither recurrence nor side effects of the medication have been detected.

[Show abstract][Hide abstract] ABSTRACT: This study evaluated the results of curettage followed by spray propane, butane, and isobutane gas combination cryosurgery in 10 patients with ameloblastoma. The patients' age ranged from 7 to 87years (mean, 31years), with equal prevalence in both men and women. Five cases were diagnosed as solid ameloblastomas and 5 as unicystic ameloblastomas. Before enucleation and cryosurgery, the unicystic lesions received marsupialisation to decrease their size. No patient showed evidence of clinical or radiographic recurrence, pathologic fracture, or infection after treatment with enucleation and cryosurgery. The most common complication was wound dehiscence, which was observed in all cases. The average follow-up period was 60.5months (range 48-108months). These results show that enucleation followed by cryosurgery is an effective therapy for managing ameloblastomas.
