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
目的：验证颞下颌关节功能紊乱（temporomandibular joint dysfunction）患者的耳部症状与副功能习惯（parafunctional habits）之间的关联关系。
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例患者的临床病历作为评估依据。纳入标准为年龄≥18岁的成年患者且病历填写完整，最终有效样本共纳入516份临床病历。研究记录了副功能习惯与耳部症状（耳鸣、听力减退、眩晕、耳闷感及平衡障碍）的存在与否。
结果：研究发现耳部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，具体表现为女性及存在至少一种副功能习惯的人群中，耳部症状的患病率更高。
结论：在本次研究样本中，颞下颌关节功能紊乱患者的耳部症状与副功能习惯呈正相关关系。
