MMTAH是一种新的临床疾病，常被误诊为颞下颌关节紊乱病。MMTAH的诊断基于方形下颌骨、索状咬肌腱膜和有限的张口。冠状突切除联合腱膜切除术预后较好。术前评估患者对张口训练的依从性很重要。咀嚼肌肌腱-腱膜增生症是一种新的临床疾病，主要表现为咬肌腱膜和颞肌肌腱增生引起的张口受限。然而，这种疾病的病因不明，它往往被误认为颞下颌关节紊乱病（TMD）。我们报告一位32岁女性病患主诉双侧下颚疼痛及张口困难。她最初被诊断为TMD，并接受了夹板治疗;然而，她的症状并没有改善。临床检查发现下颌骨呈方形，左右颞肌和咬肌有压痛，咬肌前缘有沿着压痛。她的最大张口度为30 mm。短TI反转恢复磁共振成像显示咬肌前缘和颞肌肌腱附着的冠状突周围的低强度区域。因此，根据临床和影像学结果诊断为MMTAH。进行双侧冠状突切除术，随后进行为期六个月的康复计划。手术后两年内，最大开口保持在48毫米。MMTAH被视为1型TMD，直到在日本口腔颌面外科医师协会会议上被确认为一种新疾病。从那时起，许多临床医生已经意识到这种特殊的情况，并提出了不同的治疗方式。当患者主诉张口度逐渐降低时，临床医生应将MMTAH作为鉴别诊断。
MMTAH is a new clinical entity, misdiagnosed as temporomandibular joint disorder. MMTAH is diagnosed based on a square mandible, cord-like masseter muscle aponeurosis, and limited mouth-opening. Aponeurectomy combined with coronoidectomy is the treatment of choice for a better prognosis. It is important to evaluate the patient’s compliance with mouth-opening training before surgery. Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a new clinical entity that presents mainly with trismus due to hyperplasia of the masseter aponeurosis and temporalis muscle tendon. However, the etiological factors of this disease are unknown; it is often mistreated as temporomandibular joint disorder (TMD). We report a 32-year-old female patient complaining of bilateral pain in her jaw and difficulty opening her mouth. She was first diagnosed as TMD and treated with a splint; however, her symptoms did not improve. Clinical examination revealed a square mandible, tenderness in the left and right temporalis muscles and masseter muscles, and tenderness along the anterior border of the masseter muscle. Her maximum mouth-opening was 30 mm. Short TI inversion recovery magnetic resonance imaging showed areas of low intensity at the anterior border of the masseter muscle and around the coronoid process where the temporalis muscle tendon attaches. Consequently, the diagnosis made based on the clinical and radiographic findings was MMTAH. Bilateral coronoidectomy was performed, followed by a rehabilitation program for six months. The maximum opening was maintained at 48 mm two years after the operation. MMTAH was treated as type 1 TMD until it was recognized as a new disease at the conference for the Japanese Society for Oral and Maxillofacial Surgeons. Since then, many clinicians have become aware of this particular condition, and different treatment modalities have been proposed. Clinicians should consider MMTAH as a differential diagnosis when the patient’s chief complaint is gradually decreasing mouth-opening.
