1/27. Vertical distraction of a free vascularized fibula flap in a reconstructed hemimandible: case report.The authors report a case of vertical distraction osteogenesis of a free revascularized fibula flap used to reconstruct an hemimandible lost as a result of a gunshot injury. The reconstruction procedure and the distraction protocol are described; clinical and radiological results are presented. The vertical discrepancy between the fibula and the native right hemimandible was corrected.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/27. Degloving injury to mental protuberance: a case report.Sporting injuries are increasing in frequency with the increase in leisure time. This report describes a case of degloving of the mental protuberance. Ideally this injury should be treated as soon as possible by repositioning the displaced tissue and closure. Immediate assistance was not sought until superimposed infection caused pain and swelling. Because the wound was infected, treatment was aimed at obtaining healing by secondary intention.- - - - - - - - - - ranking = 5keywords = injury (Clic here for more details about this article) |
3/27. lingual nerve injury after use of a cuffed oropharyngeal airway.The cuffed oropharyngeal airway is a modified Guedel airway and is recommended for anaesthesia in spontaneously breathing patients. To our knowledge this is the first report of transient unilateral lingual nerve palsy after the use of a cuffed oropharyngeal airway to maintain anaesthesia during arthroscopy of an ankle. The aetiology of lingual nerve damage is multifactorial. The possible mechanisms involved include anterior displacement of the mandible during insertion of the cuffed oropharyngeal airway (as in the jaw thrust manoeuvre), compression of the nerve against the mandible, or stretching of the nerve over the hyoglossus by the cuff of the cuffed oropharyngeal airway. We recommend gentle airway manipulation with the use of the cuffed oropharyngeal airway, avoidance of excessive cuff inflation and early recognition of such a complication if it occurs.- - - - - - - - - - ranking = 4keywords = injury (Clic here for more details about this article) |
4/27. Spontaneous bone regeneration of the mandible in an elderly patient: a case report and review of the literature.Spontaneous bone regeneration is an unexpected phenomenon that may take place in large mandibular defects secondary to trauma and tumor resection. One explanation for this unusual healing course is that it may be derived from the mechanism of fracture healing. A review of the literature presents several factors that may influence this process, such as the presence of periosteum and bony fragments, mandibular stabilization, soft tissue protection, the presence of infection, and a young age. Previous reports of spontaneous mandibular regeneration have all taken place in relatively young patients (5-35 years old). This paper reports a case of spontaneous bone regeneration in a 58-year-old woman who sustained an injury to her mandible from an explosive blast, and presents some explanations on how such an event could take place.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
5/27. Ewing's sarcoma of the mandible in a young patient: case report.Ewing's sarcoma, a malignant tumor, rarely occurs in children younger than 5 years of age. Although it may appear in any bone, it is more common in the axial skeleton, rarely involving the jaws (1 to 2% incidence, mostly in the mandible). The most common symptoms are pain and swelling in the affected area. history of trauma often is reported. The case of a 4-year, 10-month-old Caucasian male with a rapidly expanding mass on the right side of his face following an injury to his mandible is reported.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
6/27. Acute spinal cord injury in pregnancy: an illustrative case and literature review.Acute trauma is not all that uncommon in pregnancy. It accounts for 15% of non-obstetric maternal deaths. Moreover, about 15% of acute spinal cord injuries involve young women of childbearing age (Gilson et al., 1995). Most of the existing literature on spinal cord injury in pregnancy is concerned with the management of patients with pre-existing lesions; very few articles deal with acute injuries. We report the management of a case of acute spinal cord injury in the third trimester of pregnancy and review the major clinical issues associated with such cases.- - - - - - - - - - ranking = 6keywords = injury (Clic here for more details about this article) |
7/27. Primary post-traumatic mandibular reconstruction in infancy: a 10-year follow-up.Ballistic trauma to the craniofacial skeleton combines the challenges of complex bone injury and loss with severe soft tissue injury and violation of the naso-orbital or oropharyngeal cavities. The authors report a patient who experienced a unique ballistic injury at 28 months of age that resulted in loss of the mandibular ramus and condyle. A segmental injury to the facial nerve was also identified. Primary costochondral grafting and delayed interpositional nerve grafting was undertaken. After 10 years, the patient has nearly 40 mm of opening, with only slight deviation to the injured side. Her facial nerve regeneration provides complete orbicularis oculi function, oral competence, and only slight facial asymmetry. This traumatic reconstruction differs from that of patients with hemifacial microsomia or post-traumatic/arthritic ankylosis in that the joint space itself was spared. Thus, the costochondral graft benefits from the remaining articular disk and upper disk space and is able to rotate and translate. Function and growth are adequately re-established, even in this young pediatric patient.- - - - - - - - - - ranking = 4keywords = injury (Clic here for more details about this article) |
8/27. hemifacial spasm following a blow to the mandible causing blunt injury to the peripheral facial nerve.A 40-year-old male presented with hemifacial spasm manifesting as paroxysmal spontaneous twitches in the left peribuccal region persisting for 3 months. The symptoms began 7 days after an accident, when a signboard hit his left mandibular angle. physical examination showed no trauma-related change in his face, and no neurological abnormality except for the twitches. magnetic resonance imaging also showed no abnormalities of the facial nerve and adjacent regions. Electrophysiological studies showed synkinesis, so hemifacial spasm caused by peripheral facial nerve injury was suspect- ed. The symptoms subsided 4 months after the injury. Blunt injury to the facial nerve branches might cause hemifacial spasm.- - - - - - - - - - ranking = 7keywords = injury (Clic here for more details about this article) |
9/27. Critical hemorrhage in the floor of the mouth during implant placement in the first mandibular premolar position: a case report.Although dental implantation is considered to be a safe surgical procedure, this report focuses on a critical hemorrhaging episode associated with implant placement in the first mandibular premolar position. Excessive bleeding and formation of massive lingual, sublingual, and submandibular hematomas were the result of arterial trauma that occurred during the osteotomy preparation. The vascular injury was induced through a perforation of the lingual mandibular cortex. Critical bleeding was conservatively controlled and the case was further handled efficiently with an expectant airway management in a hospital environment. Similar case reports are reviewed in an attempt to draw attention to this rare but potentially life-endangering risk of implant dentistry. Common causes of severe hemorrhage in the floor of the mouth, anatomical considerations, bleeding control measures, and related airway issues are also discussed.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
10/27. Facial and oral reconstruction following trauma and failed chin implant: a case report.Functional and esthetic reconstruction of a patient with microgenia who sustained traumatic injury was successfully accomplished using Branemark System osseointegrated implants (Nobel Biocare USA, Inc., Yorba Linda, CA) to support a permanent dental prosthesis following mechanical and biologic reconstruction of the anterior mandible and chin. A 25-year-old glycine chin implant previously used for facial esthetic enhancement had eroded the anterior cortical plate and migrated through the medullary bone, compressing the periosteum into the apex of the anterior tooth roots. Further destruction of the lingual cortex with risk of fracture was imminent. After removal of the chin implant, a cancellous bone graft was held in place with a titanium mesh frame. The prosthetic rehabilitation consisted of two phases of mandibular implant placement followed by the construction of a porcelain-fused-to-gold implant-supported fixed prosthesis, restoring the occlusal vertical dimension as well as appropriate lip support. Restoration of function was superior to the pretreatment condition.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
