Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a disease that presents as a hard trismus due to hyperplasia of the masseter and temporalis aponeurosis. Standard surgical methods for MMTAH include masseter resection, temporalis aponeurosis, and coronoidectomy. The operation of resecting the tendon aponeurosis attached to the posterior surface of the coronoid process carries the risk of bleeding and nerve damage because it cannot be observed directly. Therefore, the authors introduce a safer method by using an ultrasonic bone scalpel for this procedure. The authors used an ultrasonic bone scalpel with a long neck blade to scrape the posterior side of the coronoid process from the bottom to the top. The authors have treated 4 cases using this technique, and in all cases, the surgical procedure was performed safely and easily. In conclusion, ultrasonic bone scalpels are effective in MMTAH surgery for removing the attachment of the stiffened temporalis muscle tendon and aponeurosis.
咀嚼肌肌腱 - 腱膜增生症（MMTAH）是一种因咬肌和颞肌腱膜增生而表现为牙关紧闭的疾病。MMTAH的标准手术方法包括咬肌切除术、颞肌腱膜切除术和冠突切除术。切除附着于冠突后表面的腱膜的手术存在出血和神经损伤风险，因为无法直接观察。因此，作者介绍了一种在此手术中使用超声骨刀的更安全方法。作者使用带有长颈部刀片的超声骨刀从底部到顶部刮除冠突后侧。作者已使用该技术治疗了4例患者，所有病例手术均安全且顺利完成。总之，超声骨刀在MMTAH手术中对于去除硬化的颞肌肌腱和腱膜附着有效。
