Outcomes of treatment with genioplasty and temporomandibular joint anchorage surgery

Abstract Background Anterior Disc Displacement without Reduction (ADDwoR) in adolescence can result in condylar resorption which produces mandibular retrusion/deviation (MR/D) in adulthood. This study aims to analyze the therapeutic effect of simultaneous genioplasty and temporomandibular joint (TMJ) anchorage surgery on ADDwoR with MR/D patients. Methods During 2016–2018, ADDwoR with MR/D cases were included and underwent TMJ anchorage surgery and genioplasty guided by digital design. Pre-/Post-surgical clinical manifestations, facial photography, radiographic data, facial shape satisfaction of clinicians/patients/third-party were recorded and analyzed. Results A total of 32 cases (52 joints) were included. The average age was 24.09. Ratio of male/female was 4/28. Visual analog pain scale (VAS) score pre-/post-surgical ranged from 3 to 9 and 0–3, with an average of 6.03 and 1.18 (p  Conclusion For ADDwoR with MR/D patients, simultaneous TMJ anchorage surgery and genioplasty can improve TMJ symptoms/functions, correct facial appearance, and enhance the degree of satisfaction. The postoperative effect is stable, safe and reliable, which is worthy of clinical promotion.
