This study re-examined the usefulness of surgery for the management of masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) through a comparison of the outcomes between patients who underwent surgery and those who did not. The duration of follow-up was 2 years. Twenty-eight patients who attended the study hospital and were given a diagnosis of MMTAH were included. Nineteen patients underwent surgery (surgical group) and nine patients were instructed to open their mouths wide once a day and did not undergo surgery (non-surgical group). Maximum mouth opening, impairment of daily activities, satisfaction, and the status of mouth opening training were evaluated after surgery. The mean increase in mouth opening after 2 years was 20.2mm in the surgical group and 2.4mm in the non-surgical group. Adequate mouth opening training led to satisfactory results 2 years postoperative, and sustained mouth opening training for 6 months after surgery was a key factor for obtaining good outcomes. The general condition and personality of individual patients should be evaluated carefully before surgery to estimate whether or not they can endure the pain associated with postoperative mouth opening training. The results of this study suggest that the surgical procedure is useful for the management of MMTAH.
本研究通过比较接受手术治疗的患者与未接受手术治疗的患者的结局，重新审视了手术治疗咀嚼肌肌腱 - 腱膜增生（MMTAH）的有效性。随访时间为2年。纳入了28名到研究医院就诊并被诊断为MMTAH的患者。19名患者接受了手术（手术组），9名患者被指示每天张大嘴巴一次且未接受手术（非手术组）。术后评估最大开口度、日常活动受限情况、满意度以及开口训练状况。2年后，手术组的平均开口度增加了20.2毫米，非手术组增加了2.4毫米。充分的开口训练在术后2年取得了满意的效果，术后持续进行6个月的开口训练是获得良好结局的关键因素。手术前应仔细评估个体患者的一般状况和性格，以估计他们是否能够忍受与术后开口训练相关的疼痛。本研究结果表明，手术方法对MMTAH的治疗是有效的。
