Prevalence of otological symptoms and parafunctional habits in patients with temporomandibular dysfunction

ABSTRACT Objective: to verify the relationship between otological symptoms and parafunctional habits in individuals with temporomandibular joint dysfunction. Methods: evaluations were based on the clinical records of 768 patients treated at a temporomandibular joint diagnostic center from 2010 to 2016. The inclusion criteria were completely filled out charts of adult patients (> 18 years of age) and the final sample comprised 516 clinical records. The presence/absence of parafunctional habits and otological symptoms (tinnitus, hearing impairment, dizziness, the sensation of plugged ears and imbalance) was recorded. Results: statistically significant associations were found between otological symptoms and both sex and the presence of parafunctional habits, as otological symptoms were more prevalent among women and individuals with at least one parafunctional habit. Conclusion: in the present sample, otological symptoms were positively associated with parafunctional habits in individuals with temporomandibular joint dysfunction.

摘要
研究目的：验证颞下颌关节功能障碍（temporomandibular joint dysfunction）患者的耳科症状与副功能习惯（parafunctional habits）之间的关联。
研究方法：本研究以2010年至2016年某颞下颌关节诊断中心收治的768例患者的临床病历为评估依据。纳入标准为年满18岁的成年患者且病历填写完整，最终有效样本包含516份临床病历。研究记录了受试者是否存在副功能习惯及耳科症状，具体包括耳鸣、听力减退、眩晕、耳闷感与平衡失调。
研究结果：数据分析显示，耳科症状与性别及副功能习惯的存在均存在统计学意义上的显著关联；女性及存在至少一种副功能习惯的受试者中，耳科症状的患病率更高。
研究结论：在本次研究样本中，颞下颌关节功能障碍患者的耳科症状与副功能习惯呈正相关。
