11/33. Vertical distraction osteogenesis of fibula transplant for mandibular reconstruction: a case report.Bone continuity defects in the mandible are caused by tumor surgery, trauma, infection, or osteoradionecrosis. Today, reconstruction of long-span mandibular defects with a free fibular flap is a routine procedure. However the bone height of the mandible after reconstruction is about half that of the dentulous mandible. Therefore, the deficiency in bone height makes implant placement impractical. In our case, because it was necessary to restore the mandibular height, a vertical distraction osteogenesis was performed on the grafted mandible of the patient who was referred to our clinic with a reconstructed mandible owing to a gunshot injury. As a result, the vertical discrepancy between the fibula and the native hemimandible of the patient was corrected. And the placement of dental implants was performed without any complications. In conclusion, we believe that the vertical distraction osteogenesis of free vascularized fibula flaps is a reliable technique that optimizes implant positioning for ideal prosthetic rehabilitation.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
12/33. The management of a plastic bullet injury to the mandible.A patient hit by a plastic bullet sustained severe facial contusion and a comminuted fracture of the mandible with bone loss. There was a non-union of the fracture. The injury and the restoration of the defect are described and the use of plastic bullets is discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = mandible (Clic here for more details about this article) |
13/33. Traumatic carotid cavernous sinus fistula due to a gun shot injury.A case of a traumatic carotid cavernous sinus fistula is presented, the result of a bullet passing through both condylar regions of the mandible. The fistula was occluded by a detachable balloon brought in place using endovascular techniques.- - - - - - - - - - ranking = 0.16666666666667keywords = mandible (Clic here for more details about this article) |
14/33. Treatment of mandibular fractures by external fixation.This series encompasses thirteen fractures of the mandible treated by external fixation. The indications were five fractures of edentulous mandible, four fractures through missile wounding, and four fractures without soft tissue lesion treated in africa. Twelve patients were found to show good or excellent results. In our indications, this method is a successful approach to the treatment of the fractured jaw.- - - - - - - - - - ranking = 0.33424282867586keywords = mandible, jaw (Clic here for more details about this article) |
15/33. Internal carotid pseudoaneurysm as a late complication of maxillofacial missile wound.A delayed formation of a pseudoaneurysm of the internal carotid artery occurred secondary to a gunshot wound of the maxillofacial region. Its treatment concurrent with the treatment of a severely comminuted fracture of the mandible has been reported.- - - - - - - - - - ranking = 0.16666666666667keywords = mandible (Clic here for more details about this article) |
16/33. Exposure of the internal carotid artery near the skull base: the posterolateral anatomic approach.Internal carotid injuries in zone III near the base of the skull are technically the most challenging of the carotid injuries. Diagnostic angiography is important to evaluate the exact site and extent of injury and the presence or absence of prograde flow in the injured segment. Vascular repair in this area is highly dependent on the adequacy of surgical exposure. Previous approaches have emphasized displacement of the mandible either by subluxation or mandibulotomy. Problems related to mandibulotomy, such as intraoral contamination, infection, and nonunion, are potential complications of this approach to the high carotid artery. In addition, it does not give adequate exposure of the internal carotid artery at the critical area, near the base of the skull. Experience gained from the extended radical neck dissection exposing the internal carotid artery up to the skull base has demonstrated that a posterolateral anatomic approach can provide superior exposure of the high carotid artery with lower morbidity and shortened operative time. This surgical approach involves cutting the sternomastoid muscle close to the mastoid and dissecting all the tissues away from the surface of the mastoid. Dividing the posterior belly of the digastric and styloid group of muscles assists in exposure of the internal carotid artery. Rarely, dissection of the facial nerve and removal of the tail of parotid add additional access to this area. This article describes the stepwise anatomic approach to the internal carotid artery near the base of the skull.- - - - - - - - - - ranking = 0.16666666666667keywords = mandible (Clic here for more details about this article) |
17/33. Tubed free flap combined with split-rib-graft for reconstruction of multiple oral cavity defects. A case report.The successful use of a conventional bone graft for mandibular reconstruction in combination with a free forearm flap is described. Two separate intraoral mucosal defects, one in the mandible and one in the palate, were covered, using the same flap and partial tubing of the flap. Three weeks post-flap-transfer the flap was successfully divided. A safe reliable and versatile technique combining nonvascularized bone graft and free flap for simultaneous reconstruction of mandibular and intraoral mucosal defects is described. Simultaneous coverage of multiple intraoral defects with tubing of the flap is found to be possible.- - - - - - - - - - ranking = 0.16666666666667keywords = mandible (Clic here for more details about this article) |
18/33. Bone imaging in the assessment of en bloc osteocutaneous autotransplantation.A patient is presented who sustained an avulsed portion of the mandible and all soft tissues of the floor of the oral cavity, requiring an autogenous en bloc transplant to replace the avulsed tissues. The clinical role of bone imaging in assessing the patency of the microvasculature and viability of the vascularized osteocutaneous graft is discussed, and the criticality of the time of image acquisition in prognosticating the success of the transplantation is emphasized.- - - - - - - - - - ranking = 0.16666666666667keywords = mandible (Clic here for more details about this article) |
19/33. Spontaneous regeneration of the mandible in a child. A sequel to partial avulsion as a result of a war injury.A 7-year-old child sustained a severe avulsion injury to the left mandible leaving a 6 cm. gap. A Kirschner wire alone was used for immobilization and stabilization. Radiographs of the mandible 2 1/2 years later showed complete osteogenesis and solid bone formation over the Kirschner wire. The young age of the patient was definitely important in influencing this favourable result. The author's experience in older war injuries patients, using the same procedure, has shown no such bone formation. The source of osteogenesis is believed to be from mesenchymal cells of the soft tissue remaining in the gap. The theories pertaining to the source and mode of osteogenesis in this case are discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
