Masticatory muscle tendon-aponeurosis hyperplasia is a new disease entity characterized by limited mouth opening due to contracture of the masticatory muscles, resulting from hyperplasia of tendons and aponeuroses. In the case of masseter muscle type, the face displays a square mandible configuration. Pharmacotherapy, occlusal splints and physical therapy are ineffective. This study evaluated the long-term results of aponeurectomy of the masseter muscle with coronoidectomy to release the temporal muscle tendon. The subjects were 10 patients who underwent surgery between 2000 and 2005. Mean maximum mouth opening before surgery was 21.8mm (range 17-29 mm). All patients received bilateral aponeurectomy of the masseter muscle and coronoidectomy. Three patients additionally underwent bilateral anglectomy for esthetic reasons. After discharge, one patient did not return to the hospital. Data from the other nine patients were analyzed. The mean duration of follow-up was 4 years. At final follow-up, the maximum mouth opening was >44 mm in four patients, 40-44 mm in three patients, and 35-39 mm in two patients. Overall satisfaction was excellent or good in all patients.
咀嚼肌肌腱-腱膜增生症是一种新的疾病实体，其特征为由于咀嚼肌的肌腱和腱膜增生导致的口部张开受限，从而导致口部张开受限。在咬肌型中，面部呈现方形下颌骨形态。药物治疗、咬合夹板和物理治疗均无效。本研究评估了行咬肌肌腱-腱膜切除术联合髁突切除术以松解颞肌肌腱的长期疗效。该研究共纳入了 10 名于 2000 年至 2005 年间接受手术的患者。术前最大张口度的均值为 21.8mm（范围为 17-29mm）。所有患者均接受双侧咬肌肌腱-腱膜切除术和髁突切除术。出于美观考虑，3 名患者还接受了双侧下颌角切除术。出院后，1 名患者未返回医院。对其余 9 名患者的数据进行了分析。平均随访时间为 4 年。末次随访时，4 名患者的最大张口度>44mm，3 名患者为 40-44mm，2 名患者为 35-39mm。所有患者的总体满意度均为优或良。
