Abstract

Background: The temporomandibular joint is a unique bi-condylar joint involved in mastication and speech. Temporomandibular joint disorders (TMD) have a range of symptoms, including aural symptoms, and are present in approximately 75% of normal populations. The present study examined the relationship between signs and symptoms of TMD and mouth opening, gender, joint and aural symptoms, and hearing loss.

Methods: The study involved 464 healthy Greek university students (156 men and 308 women) with a mean age of 19.6 years. Age, gender and maximum mouth opening was recorded. Mouth opening was measured using Vernier calipers. An anamnestic questionnaire was used to stratify the subjects into four groups based on TMD severity. Aural symptoms and an audiogram were recorded for each subject too. Data were analyzed using multifactor ANOVA, chi-square, t-test, Mann-Whitney and Kruskal-Wallis tests.

Results: The overall incidence of TMD signs and symptoms was 73.3%. The incidence and severity was greater in females than males (p-value 0.0001 < 0.05). The number of aural symptoms was associated to the TMD severity (p-value 0.0001 < 0.05) as well as maximum mouth opening (p-value 0.004 < 0.05). Audiometry showed that moderate and severe TMD was associated with hearing loss of median and low tones respectively (p-value 0.0001 < 0.05). TMJ pain (p-value 0.0001 < 0.05), TMJ ankylosis (p-value 0.0001 < 0.05), bruxism (p-value 0.0001 < 0.05) and ear itching (p-value 0.0001 < 0.05) were also found to be statistically different between TMD and non-TMD subjects.

Conclusions: TMD signs and symptoms were more common and severe in females than males. TMD severity is correlated with the degree of mouth opening and the number of aural symptoms. The absence or presence of mild TMD are associated with normal audiograms while moderate and severe TMD are related to hearing loss in median and low tones respectively. Bruxism, joint ankylosis, joint pain and ear itching were more common in TMD than non-TMD patients.

颞下颌关节紊乱的体征和症状与开口程度和听力损失有关。

背景:颞下颌关节是一种独特的双髁关节，与咀嚼和言语有关。颞下颌关节紊乱(TMD)有一系列症状，包括听觉症状，大约75%的正常人群都有这种症状。本研究考察了TMD的体征和症状与开口、性别、关节和听觉症状以及听力损失之间的关系。方法:该研究涉及464名健康的希腊大学生(156名男性和308名女性)，平均年龄为19.6岁。记录年龄、性别和最大开口。用游标卡尺测量开口。根据TMD的严重程度，采用回顾性问卷将受试者分为四组。每位受试者的听觉症状和听力图也被记录下来。数据分析采用多因素方差分析、卡方检验、t检验、Mann-Whitney检验和Kruskal-Wallis检验。结果:TMD症状和体征的总发生率为73.3%。女性的发病率和严重程度高于男性(p值0.0001 < 0.05)。听力症状数与TMD严重程度(p值0.0001 < 0.05)和最大张口(p值0.004 < 0.05)相关。听力测量显示，中度和重度TMD分别与中音和低音听力损失相关(p值0.0001 < 0.05)。颞下颌关节疼痛(p值0.0001 < 0.05)、颞下颌关节强直(p值0.0001 < 0.05)、磨牙(p值0.0001 < 0.05)和耳痒(p值0.0001 < 0.05)在TMD与非TMD患者之间也有统计学差异。结论:TMD的体征和症状女性比男性更常见和严重。TMD的严重程度与张口程度和听觉症状的次数相关。轻度TMD的缺失或存在与听音正常相关，中度和重度TMD分别与中音和低音听力损失相关。磨牙、关节强直、关节疼痛和耳部瘙痒在TMD患者中较非TMD患者更为常见。
