Autogeneous coronoid process as free graft for reconstruction of mandibular condyle in patients with temporomandibular ankylosis.

OBJECTIVE

This study was conducted to determine the efficacy of using the autogeneous coronoid process as free graft for reconstruction of mandibular condyle and to achieve structural, functional, as well as esthetic rehabilitation of patients with temporomandibular joint (TMJ) ankylosis.

MATERIALS AND

METHODS

This article presents the clinical results of an evaluation of ten cases of TMJ ankylosis treated by using autogeneous coronoid process as free graft for reconstruction of mandibular condyle after resection of ankylotic mass.

RESULTS

Satisfactory mouth opening were obtained in all ten cases. No patient showed signs of re-ankylosis at 12 months follow-up. Preoperative mouth opening ranged from 0 to 15 mm with mean being 4.8 mm. As a result of successful procedure, the immediate postoperative mouth opening increased ranging from 24 to 31 mm (mean, 26.5 mm). Follow up of patients at the first and 12th month showed good results with increase in mouth opening from a range of 24 to 31 mm (mean, 27.8 mm ) to 26 to 36 mm (mean, 33.13 mm).

CONCLUSION

The results of this study suggest that the autogeneous coronoid process as free graft is a suitable graft material for reconstruction of mandibular condyle after resection of ankylotic mass.
