영문 초록

Purpose: The purpose of this study is to prove that orthognatic surgery on asymmetric prognathism patients improve the temporomandibular dysfunction. Materials and methods: All 30 patients underwent mandibular setback with B-SSRO including 22 patients Le Fort I surgery in KyungHee medical center. Preoperative and postoperative PA cephalograms & transcranial radiographs were measured midline deviation in Mx and Mn, occlusal canting change, condyle position, the temporomandibular dysfunction were checked before surgery, within 1 month after surgery, 3~6 months, 12-24 months after surgery respectively. Results: The temporomandibular dysfunction were relieved after surgery in 17 patients of 25 patients. Conclusion: Orthognatic surgery may benefit the temporomandibular joint dysfunction in facial asymmetry patients by obtaining a postoperative stable occlusion and better physiologic neuromuscular function. Specially impovement of occlusal canting may reduce condyle displacement of midline deviation side and the temporomandibular joint dysfunction.
