The aim of this study was to investigate the frequency of otologic symptoms and their relationship to orofacial signs and symptoms of temporomandibular disorder (TMD), and the effect of orofacial myofunctional therapy. The study was conducted on eight asymptomatic subjects (Group C) and 20 subjects with articular TMD, randomly distributed over two groups: one treated using orofacial myofunctional therapy (OMT Group) and a control group with TMD (Group CTMD). Patient selection was based upon the Research Diagnostic Criteria for TMD (RDC/TMD). All subjects submitted to a clinical examination with self-reporting of symptom severity, and to orofacial myofunctional and electromyographic evaluation at diagnosis and again, at the end of the study. Correlations were calculated using the Pearson test and inter- and intragroup comparisons were made (p < 0.05). In the diagnosis phase, subjects with TMD reported earache (65%), tinnitus (60%), ear fullness (90%), and 25% of the asymptomatic subjects reported tinnitus. The otologic symptoms were correlated with tenderness to palpation of the temporomandibular muscles and joints and with orofacial symptoms. Only the OMT group showed a reduction of otologic and orofacial symptoms, of tenderness to palpation and of the asymmetric index between muscles. OMT may help with muscle coordination and a remission of TMD symptoms.
本研究旨在调查耳科症状的发生率及其与颞下颌关节紊乱病（TMD）的口面部体征和症状的关系，以及口面部肌功能治疗的效果。该研究对8名无症状受试者（C组）和20名患有关节型TMD的受试者进行，这些受试者随机分为两组：一组采用口面部肌功能治疗（OMT组），另一组为TMD对照组（CTMD组）。患者选择基于TMD研究诊断标准（RDC/TMD）。所有受试者均接受临床检查，自行报告症状严重程度，并在诊断时以及研究结束时再次接受口面部肌功能和肌电图评估。使用Pearson检验计算相关性，并进行组间和组内比较（p<0.05）。在诊断阶段，TMD受试者报告有耳痛（65%）、耳鸣（60%）、耳闷（90%），25%的无症状受试者报告有耳鸣。耳科症状与颞下颌肌肉和关节触诊压痛以及口面部症状相关。只有OMT组的耳科和口面部症状、触诊压痛以及肌肉间不对称指数有所降低。口面部肌功能治疗可能有助于肌肉协调和TMD症状的缓解。
