1/44. Reconstruction of the horizontal rami of the mandible following avulsion in childhood.

    A 7-year-old boy was involved in a road traffic accident in October 1971, and apparently had been dragged along face downwards with resultant avulsion of the entire horizontal mandibular rami, and most of the mandibular alveolar soft tissue and teeth. Repair by metal implants was attempted but these proved unsatisfactory, and soft tissue replacement for the missing alveolus was carried out by flap raised from arm. Rib grafting was carried out on three occasions at almost yearly intervals, but each time, probably owing to vascular insufficiency, non-union (or more correctly non-replacement) occurred in the left canine region. To "import" a new blood supply, and free some of the scar tissue, a compound muscle/bone/skin flap bearing the clavicle and sternomastoid muscle was transposed to the mandibular bed. This form of grafting was used extensively in world war i to repair facial gunshot wounds, and the transposed blood supply enabled success in the pre-antibiotic period. Bony union is now satisfactory 5 years after injuries and dentures have been recently fitted; speech is normal, the child's facial contours acceptable, and mastication has been satisfactory during this period.

2/44. Simultaneous reconstruction of the area of the temporo-mandibular joint including the ramus of the mandible in a posttraumatic case. A case report.

    A new technique for the simultaneous reconstruction of the glenoid fossa and the ramus of the mandible is described. By combining and adapting procedures already described, the missing bone of the zygomatic arch, temporo-mandibular joint and ramus was replaced in one operation in a post-traumatic case. The indication for this operation is discussed. It is rather limited. The technique can be used for reconstruction of skeletal defects after tumour resection and in congenital aplasias of this region.

3/44. 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.

4/44. Dislocation of the mandible: a case report.

    Dislocation of the mandible is a possible complication of direct tracheal laryngoscopy. The temporomandibular joint (TMJ) is unique in that any movement of the bone always causes movement in both joints simultaneously. The entire TMJ is surrounded by a ligamentous capsule and is stabilized by 3 ligaments. Four muscles of mastication move the mandible with great power. The lateral pterygoid muscle has nearly horizontal muscular fibers and is chiefly responsible for dislocating the mandibular condyle and articular disc past the articular eminence into the infratemporal fossa, causing the patient great pain and distress. If mandibular dislocation should occur, prompt recognition and treatment of the dislocation is recommended. There are steps, used by dentists, which can be employed by the nurse anesthetist to relocate the mandible. The technique for intraoral bimanual relocation of the mandible is described.

5/44. 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.

6/44. 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.

7/44. 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.

8/44. Simultaneous reconstruction of large maxillary and mandibular defects with a fibular osteocutaneous flap combined with an anterolateral thigh flap.

    This article reports the simultaneous reconstruction of maxillary and mandibular defects caused by a close-range gunshot blast to the face with one fibular osteocutaneous flap combined with an anteroateral fasciocutaneous flap. A fibular osteocutaneous flap was used for both mandibular and maxillary defects, using multiple osteotomies and discarding a central bony segment and an oral floor defect. An anterolateral thigh flap was used to cover a three-dimensional defect of both the intraoral mucosal region, as well as external skin and soft tissue defects, including some on the upper and lower lips. The results demonstrated that the method was a good choice in the reconstruction of large composite facial defects, both aesthetically and functionally.

9/44. Distraction osteogenesis in an anterior mandibular bone defect utilizing lingual periosteal release: a case report.

    This clinical report presents a modified distraction technique to achieve height in the vector of distraction. The success of distraction osteogenesis depends on both biologic and biomechanical factors. The focus in this case is on correcting the direction of distraction; incorrect distraction direction is a frequent complication associated with distraction osteogenesis in the mandible. A 21-year-old man presented with a 10-mm vertical bone defect in the anterior mandible caused by facial trauma. The treatment chosen was distraction osteogenesis. After osteotomizing a bone segment and slitting the lingual periosteum, the bone segment was advanced anteriorly 4 mm and an extra-alveolar distraction device was applied. This approach allows the distraction device to be placed vertically, thus preventing lingual shift. The newly created alveolar ridge fully met prosthodontic requirements for a predictable outcome.

10/44. ITI implants and Dolder bars in the treatment of large traumatic defect of mandible: a clinical report.

    The development of more sophisticated implant techniques to produce satisfying results improves the precise planning of both the surgical phase of the implantation and the following prosthetic rehabilitation. Ball and bar attachments are the main retainer systems for implant-bearing overdentures to achieve a successful treatment in the partial or full edentulism. In this clinical report, a 23-year-old male patient, presented with a large traumatic defect in the anterior mandible, was treated with ITI implant and ITI Dolder bar combinations. The reason to prefer this kind of treatment depends on the highest retention capacity and cleaning facilities of the system.
