Objectives: To evaluate the efficacy of the above procedure by evaluating the increase in mouth opening, by assessing the resorption of the newly reconstructed RCU, by assessing any occlusal disturbances, deviation upon mouth opening and obstructive sleep apnoea, caused by decrease in height of the ramus of the mandible as well as to evaluate complications of the procedure, if any. Materials and Method: 13 patients (22 joints) with TMJ ankylosis along with resection of the ankylosed condyle, underwent L-shaped ramus osteotomy. Patients were followed up for an average of 14.07 months (range 12–17 months). Results: In all patients, increase in mouth opening was noted, from an average of 3.3 mm preoperative to 32.2 mm at maximum follow up. When comparing the height of the newly reconstructe...
