[Function of disk reposition in the treatment of traumatogenic temporomandibular joint ankylosis].
OBJECTIVE
To investigate the method and results of disk reposition in the treatment of traumatogenic TMJ ankylosis.


METHODS
In 19 cases of traumatogenic ankylosis of TMJ, the dislocated disks were repositioned during anthroplasty. In the operation, the dissection of dislocated disk was performed carefully around the TMJ. The disk was repositioned to its anatomic location over the top of condylar stump, then the lateral aspect of the disk was sutured to the soft tissue of zygomatic root.


RESULTS
At the last follow-up examination, interincisal opening distance ranged from 24 to 43 mm in all cases (mean 32.63 mm), which approached or reached the normal level. No recurrence and TMJ symptom were found during the period of follow-up.


CONCLUSIONS
The disk repositioning in treatment of traumatogenic TMJ ankylosis is a feasible and effective approach to reconstruct the structure and function and prevent recurrence.
