We examined a large population of patients undergoing temporomandibular joint (TMJ) surgery and provide a documentation of the average patient population, frequency of procedures, frequency of repeat procedures, and trends in open (arthrotomy) versus closed (arthroscopy) TMJ surgery. Data on 194 TMJ surgical procedures was extracted from line item claims information collected by Trigon Blue Cross/Blue Shield of Virginia. The frequency of arthroscopy increased during the study, while the incidence of arthrotomies remained relatively low. Approximately half of the hospitals statewide did not perform either procedure. There was a low frequency (3%) of repeat procedures. In the Commonwealth of Virginia, since the advent of TMJ arthroscopy, it has become the preferred surgical technique for treatment of internal derangement. There is a low incidence of repeat procedures for both types of treatment. Analysis of insurance carrier computer records is a valid technique for evaluating trends in surgical care.
我们研究了大量接受颞下颌关节（TMJ）手术的患者群体，并提供了关于患者平均群体、手术频率、重复手术频率以及开放性（关节切开术）与闭合性（关节镜检查）TMJ手术趋势的记录。从弗吉尼亚州三角蓝十字/蓝盾收集的项目明细理赔信息中提取了194例TMJ外科手术的数据。在研究期间，关节镜检查的频率增加，而关节切开术的发生率相对较低。全州约一半的医院未进行这两种手术。重复手术的频率较低（3%）。在弗吉尼亚州，自TMJ关节镜检查出现以来，它已成为治疗内部紊乱的首选手术技术。两种治疗方式的重复手术发生率都较低。分析保险公司的计算机记录是评估手术护理趋势的有效技术。
