Abstract

Introduction: The treatment of temporomandibular joint is mainly surgical and aims at restoring the function of joint and correcting the aesthetics deformity caused by ankylosis. Studies are available in the literature which showed that there is osteogenic potential in condylar stump remaining after gap arthroplasty, especially in children. Our objective was to assess the growth of ramus operated after surgery using orthopantomogram as the tool of assessment.

Materials and method: Fifteen patients of prospective study design were selected for study. This study was undertaken to evaluate the mandibular ramal growth in TMJ ankylosis patients treated without growth center transplantation using orthopantomogram as a tool of assessment.

Results: Mean ramal length of the operated right side was found to be 42.02 mm in immediate postoperative, 43.18 mm in sixth month postoperative and 44.57 mm in 1 year postoperative follow-up. Mean ramal length of the operated left side was found to be 40.15 mm in immediate postoperative, 42.10 mm in sixth month postoperative and 44.80 mm in 1 year postoperative follow-up.

Conclusion: Our investigations showed that mandibular growth rate increases after successful treatment of ankylosis in children. One drawback of this treatment protocol that we observed was that the total growth deficit manifested in all our patients could not be made up.
