Injection of botulinum toxin type A (BTX-A) into the lateral pterygoid muscles is a recently reported treatment for habitual dislocation of the temporomandibular joint (TMJ). We report five cases of dislocation in elderly patients with neurological or other severe systemic disease, and their successful treatment with one injection of BTX-A into the lateral pterygoid muscles. This is a relatively conservative option. Injection into the muscle is straightforward and can be done in outpatients with few complications. We recommend it as the first choice for patients with habitual dislocation and systemic or neurological diseases, particularly in the elderly.
向翼外肌注射A型肉毒毒素（BTX-A）是最近报道的一种治疗颞下颌关节（TMJ）习惯性脱位的方法。我们报告了5例患有神经系统疾病或其他严重全身性疾病的老年患者的脱位情况，以及通过向翼外肌注射一次BTX-A成功治疗的案例。这是一种相对保守的选择。肌肉注射操作简单，可在门诊进行，并发症少。我们建议将其作为习惯性脱位且患有全身性或神经系统疾病患者的首选治疗方法，尤其是老年患者。
