Egyptian dental journal
Objectives: The aim of the present study is to compare the clinical outcomes of the widely used autogenous costochondral grafts with autogenous coronoid process grafts for condylar reconstruction in treatment of unilateral temporomandibular joint (TMJ) ankylosis in adults. Patients and Methods: Nine patients of unilateral TMJ ankylosis in age group older than 18 years were selected from the outpatient clinic , they were 6 males and 3 females, the condyle was reconstructed after gap arthroplasty
... er gap arthroplasty in 4 patients with costochondral grafts and with coronoid process graft in 5 patients. Clinical and radiographic examination was done postoperatively to compare between the 2 groups. Results: The clinical outcomes in both groups were satisfactory and comparable with no significant differences between the 2 groups in the measurements before and after the operation regarding mouth opening, lateral excursion and mandibular deviation. Complications related to the donor site were much higher in the costochondral group. Conclusion: Autogenous coronoid process is a promising alternative graft to the traditional costochondral graft for condylar reconstruction in adult patients with TMJ ankylosis.
