ABSTRACT: The potential role of disc repositioning in preventing postsurgical recurrence of traumatogenic temporomandibular joint (TMJ) ankylosis was investigated. Seventeen cases of traumatogenic TMJ ankylosis underwent disc repositioning during arthroplasty. During surgery, the dislocated disc was carefully dissected outside the ankylotic TMJ and repositioned over the top of the condylar stump, and then sutured to the soft tissue of the zygomatic root. In the 22 ankylotic TMJs of the 17 patients, dislocated discs were found in front of the ankylotic TMJ, behind the ankylotic TMJ or between the ramus and fossa. At the last follow-up (longer than 1 year) examination, interincisal opening distances ranged from 24 to 43 mm (mean 32.86 mm). No recurrence and TMJ symptoms were found during the period of follow-up. Disc repositioning in the treatment of traumatogenic TMJ ankylosis proves to be a feasible and effective method of preventing recurrence of this condition.

ABSTRACT: Reimplantation of frozen autogenous lesioned mandible was performed in 31 patients with mandibular bone cysts and tumours. 26 reimplanted grafts survived without complications following surgery. Two cases had postoperative infections which were resolved following appropriate antibiotic treatment. Three grafts were removed due to the severe infection and wound dehiscence. The follow-up from 6 months to 4 years showed that there was no recurrence of the primary lesion in the 28 successful cases. Satisfactory facial contour after surgery was achieved in 19 patients, while other patients showed relatively mild facial disfigurement. The inferior alveolar nerve was repaired in 4 cases and a functional evaluation was made using an acupuncture pressure tester.

ABSTRACT: The condylar necks of young rats are fractured on this experiment.Fractures are treated with nonfixation and fixation,The growth and development of mandible can be interrupted in two groups,with a relatively small in condylar head,a relatively thick in condylar neck.A coronoid and a mandible length are relatively short.But the growth and development of mandible almost are completed,bilateral mandibles are almost symmetry except for ramus.The difference are not found in between two groups.The results of this study implied that young condylar neck fracture may be treated by conservation.
