Ear movement disorders are rarely reported. Although some patients may respond to botulinum toxin injections, reports on surgical treatment options remain limited.
A 57-year-old woman was diagnosed with auricular dystonia, which was refractory to botulinum toxin injections. Since involuntary movement and pain were predominantly present on the right side and the patient rejected the implantation of a mechanical device, we decided to perform left pallidothalamic tractotomy. Immediately following lesioning, bilateral ear movements and right auricular pain ceased with no complications.
Stereotactic neurosurgical treatment can be an alternative for auricular dystonia.
Ear movement disorders, such as auricular myoclonus or dystonia, are rarely reported.The present case was refractory to repetitive botulinum toxin injections and oral medications.To the best of our knowledge, this is the first case of auricular dystonia that successfully improved with stereotactic neurosurgical treatment (pallidothalamic tractotomy).
耳部运动障碍很少见报道。尽管一些患者可能对肉毒毒素注射有反应，但关于手术治疗选择的报道仍然有限。
一位 57 岁女性被诊断为耳肌张力障碍，对肉毒毒素注射无反应。由于右侧存在明显的不自主运动和疼痛，且患者拒绝植入机械装置，我们决定行左侧苍白球丘脑束切断术。即刻进行神经核团损毁后，双侧耳部运动和右侧耳痛停止，无并发症发生。
立体定向神经外科治疗是耳部肌张力障碍的一种可选治疗方法。
耳部运动障碍，如耳肌阵挛或肌张力障碍，很少见。本例患者对重复肉毒毒素注射和口服药物治疗均无反应。据我们所知，这是首例通过立体定向神经外科治疗（苍白球丘脑束切断术）成功改善的耳部肌张力障碍病例。
