Temporomandibular disorders are a set of musculoskeletal dysfunctions within the masticatory system, with multiple etiologies.
Since craniocervical dystonia can involve the same neuromuscular structure as the temporomandibular joint, we sought to assess the correlation between temporomandibular disorders and craniocervical dystonia.
We applied the Research Diagnostic Criteria for Temporomandibular Disorders to 42 patients with craniocervical dystonia, in order to identify orofacial pain and temporomandibular characteristics on the day of botulinum toxin injection.
Twenty-two patients (52.3%) reported temporomandibular joint pain; 24 (57.1%), joint sounds; 20 (47.6%), masticatory muscle pain; and 21 (50%), diminished jaw mobility. The patients with oromandibular dystonia presented temporomandibular disorders more frequently than did patients with other types of craniocervical dystonia (p<0.001).
Temporomandibular disorders occur frequently in patients with oromandibular dystonia. Further studies should address the proper treatment of temporomandibular disorders associated with dystonia.
颞下颌关节紊乱病是咀嚼系统中的一组肌肉骨骼功能障碍，病因多样。
由于颅颈肌张力障碍可累及与颞下颌关节相同的神经肌肉结构，我们试图评估颞下颌关节紊乱病与颅颈肌张力障碍之间的相关性。
我们对42例颅颈肌张力障碍患者应用颞下颌关节紊乱病研究诊断标准，以确定肉毒毒素注射当天的口面部疼痛和颞下颌关节特征。
22例患者（52.3%）报告有颞下颌关节疼痛；24例（57.1%）有关节弹响；20例（47.6%）有咀嚼肌疼痛；21例（50%）有下颌活动度减小。口下颌肌张力障碍患者比其他类型颅颈肌张力障碍患者更常出现颞下颌关节紊乱病（p<0.001）。
口下颌肌张力障碍患者中颞下颌关节紊乱病很常见。进一步的研究应探讨与肌张力障碍相关的颞下颌关节紊乱病的恰当治疗方法。
