Abstract
Purpose:The aim of this study was to compare the preoperative and 1-year postoperative clinical and radiological findings of the patients after unilateral temporomandibular joint (TMJ) discectomy with inter-positional abdominal dermis-fat graft.Materials and Methods:Fourteen patients underwent unilateral discectomy and dermis-fat grafting between 2008 and 2010. Preoperative and 1-year postoperative clinical parameters such as maximum mouth openings (MMO) and lateral movements (LM) of the mandible were recorded. Additionally, preoperative and postoperative magnetic resonance imagingwas obtained to determine the duration of operated TMJs.Results:All of the 14 patients showed the improvement in mandibular mobility and function. There was a significant increase in the MMO and LM during the follow-up period. Pain levels at follow-up were significantly lower than the preoperative levels. Radiologically, the dermis-fat graft was detected within the joint or surrounding the condyle in all 14 operated joints. The graft material that was found within the joint space was mainly grey in four joints. Ten joints showed heterogeneous material composed of fat interspersed with grey tissue.Conclusion:Discectomy and dermis-fat grafting appears to be a successful surgical option regarding to the clinical parameters. However, summed degenerative changes depending on surgical operation should be retained.
