1/12. Correction of posttraumatic maxillary deficiency by anterolateral alveolar osteotomy.Anterolateral alveolar osteotomy was performed in a patient who experienced facial trauma in a traffic accident. Bony sequela had remained in the maxilla after the emergency surgery, affecting the facial appearance. A different technique of osteotomy for this unusual type of deformity is presented.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/12. Non-free osteoplasty of the mandible in maxillofacial gunshot wounds: mandibular reconstruction by compression-osteodistraction.We have treated 33 young men with medium to large (3-8 cm) bony and soft tissue defects of the lower third of the face caused by gunshot wounds. After debridement, collapsing the proximal segments for primary approximation of soft and hard tissues and a closed osteotomy of a small fragment of mandible, we used an original compression-distraction device, designed in 1982 and tested during 1983 (analogous devices were absent at that time) to reposition the mandible and cause callus to form (during distraction) between the fragment and to use the remaining stumps of bone to fill in the defect. The soft tissues were repaired at the same time. Twenty-eight of the patients presented within a few hours of injury, and the remaining five had old injuries. The only complications were in the group with old injuries where four patients developed abscesses that required drainage, but these did not interfere with the process of osteogenesis. All 33 patients had good functional and aesthetic results within 3-4.5 months. The method allows a bloodless minimally traumatic procedure which can be carried out in one stage. The results compare very favourably with the classic methods of the treatment of mandibular gunshot injuries.- - - - - - - - - - ranking = 0.0010866408740523keywords = process (Clic here for more details about this article) |
3/12. Prosthodontic rehabilitation of a patient with total avulsion of the maxilla: a clinical report.patients with complete avulsion of the palate may require extensive surgical and prosthodontic rehabilitation. The prosthesis should replace not only missing teeth but also lost soft tissues and bone, including the hard palate, residual alveolar ridges, and in some situations, the soft palate. This clinical report describes the prosthetic rehabilitation, after appropriate surgical options had been exhausted, of a patient with bilateral traumatic avulsion of the maxilla.- - - - - - - - - - ranking = 0.27733425021535keywords = alveolar, ridge (Clic here for more details about this article) |
4/12. An unusual cause of locked jaw and its airway management.We describe the management of a patient impaled through the medial aspect of the left orbit by the brake lever of a mountain bike which immobilized her jaw by obstructing the right coronoid process of the mandible and blocked access to the mouth and trachea. The fire service used special equipment to cut out the rest of the bike from the handle bar. The patient with the penetrating brake lever attached to the handlebar in situ was transported to the hospital by rescue helicopter. The assessment and safe airway management and potential difficulties are discussed.- - - - - - - - - - ranking = 0.0010866408740523keywords = process (Clic here for more details about this article) |
5/12. Traumatic gemination--triple tooth. Survey of the literature and report of a case.Gemination and twinning are two rarely encountered developmental abnormalities. Although the precise etiology remains unknown, genetic predisposition is often suggested in the process. In the present study a maxillary incisor with three crowns of conical shape and three roots which were presumed to be the gemination of the tooth due to trauma, is reported.- - - - - - - - - - ranking = 0.0010866408740523keywords = process (Clic here for more details about this article) |
6/12. The application of panoramic zonography to the diagnosis of maxillofacial fractures.Traditionally, multiple radiographic views and techniques were required to elucidate the nature and extent of fractures of the maxillofacial complex. As a result, patient cost in terms of time, expense, manipulation, and radiation exposure scaled upward. Synthesis and interpretation of the fragmented bits of information from multiple films also constituted a labor-intensive process. A new imaging modality, panoramic zonography, provides precise anatomic imaging of preselected areas of interest with minimal radiation exposure. The usefulness of this technique in the diagnosis, treatment, and follow-up of traumatic events in the mandibular and maxillofacial regions is illustrated by a series of cases.- - - - - - - - - - ranking = 0.0010866408740523keywords = process (Clic here for more details about this article) |
7/12. Bilateral microneurosurgical reconstruction of inferior alveolar nerves via autogenous sural nerve transplantation.Microneurosurgical operative techniques permit satisfactory restoration of sensation in many lesions of the inferior alveolar nerve. Therefore, restoration of the sensory deficit is becoming increasingly more important in the total functional rehabilitation of individuals with mandibular continuity defects involving transection of or permanent damage to the inferior alveolar nerve. This article reviews the case history of a young man who underwent bilateral osseous mandibular reconstruction and microneurosurgical reconstruction of his inferior alveolar nerves following severe maxillofacial trauma. A new technique for isolating the sural nerve is introduced to facilitate harvesting of the graft. Scanning electron microscopic examination of the resected proximal inferior alveolar nerve is recommended to determine the prognosis for regeneration across the proximal anastomosis and to decide whether secondary resection and reanastomosis of the distal anastomosis is indicated when anesthesia persists 9 to 12 months after initial transplantation of a long donor nerve.- - - - - - - - - - ranking = 1.6keywords = alveolar (Clic here for more details about this article) |
8/12. Correction of implant malalignment by segmental osteotomy: a case report.This case report demonstrates that the position of malaligned osseointegrated implants can be corrected by a segmental osteotomy procedure with no loss of implants or bone support. The patient was a healthy teenage girl who sustained facial trauma with loss of teeth and alveolar bone. The defect was initially bone grafted. Branemark implants were simultaneously placed in the graft. Their initial unfavorable positions and inclinations were later corrected by a segmental osteotomy.- - - - - - - - - - ranking = 0.2keywords = alveolar (Clic here for more details about this article) |
9/12. Transcatheter arterial embolization as treatment for life-threatening maxillofacial injury.A rare case of massive maxillofacial hemorrhage, which was controlled by transcatheter arterial embolization, is reported. A 23-year-old man with massive nasal and oral hemorrhage caused by maxillofacial fracture was admitted. Emergency angiography demonstrated extravasation of contrast material from the posterior superior alveolar artery, which was immediately embolized using gelatin sponge particles. This case shows that transcatheter arterial embolization is useful and effective for the treatment of massive hemorrhage resulting from severe maxillofacial injury.- - - - - - - - - - ranking = 0.2keywords = alveolar (Clic here for more details about this article) |
10/12. Eagle's syndrome caused by traumatic fracture of a mineralized stylohyoid ligament--literature review and a case report.Eagle's syndrome is the common name for a series of clinical symptoms arising from an elongated styloid process of the temporal bone. The syndrome is named for Watt W. Eagle, M.D., who described its occurrence in a series of articles beginning in 1937. Common presentations of Eagle's syndrome are a post-tonsillectomy, nerve irritation and an impingement on either the external or internal carotid artery. The styloid process is the first section of the stylohyoid chain, formed by the stylohyoid ligament. Sections of this structure have the ability to mineralize, forming a rigid segment. This mineralized segment is then subject to fracture due to traumatic injury. The literature is reviewed for examples of traumatic fracture of the mineralized stylohyoid ligament, and a clinical case is presented.- - - - - - - - - - ranking = 0.0021732817481047keywords = process (Clic here for more details about this article) |
