Summary
Treatment for temporomandibular joint dysfunction significantly improved subjective ear symptoms in patients. While hearing and vestibular issues were often unrelated, a potential link between jaw dysfunction and cochlear defects was observed.
Area of Science:
- Otolaryngology
- Dentistry
- Neurology
Background:
- Temporomandibular joint (TMJ) dysfunction is associated with various symptoms.
- Ear-related symptoms are frequently reported by patients with TMJ dysfunction.
Purpose of the Study:
- To investigate the prevalence of subjective ear symptoms in patients with TMJ dysfunction.
- To evaluate the impact of TMJ dysfunction treatment on these symptoms.
- To assess the relationship between TMJ dysfunction and audiological/vestibular findings.
Main Methods:
- Study included 47 patients diagnosed with temporomandibular joint dysfunction.
- Subjective ear symptoms were documented and assessed.
- Audiometric and neuro-otological examinations were performed.
- Treatment outcomes for TMJ dysfunction were evaluated regarding symptom improvement.
Main Results:
- 100 subjective ear symptoms were reported by 39 patients.
- Treatment eradicated or reduced 56% of these symptoms.
- Hearing defects were audiometrically confirmed in 8 cases, with 7 likely unrelated to TMJ.
- Neuro-otological and vestibular disturbances were noted, with varying degrees of suspected TMJ involvement.
Conclusions:
- Treatment of temporomandibular joint dysfunction offers significant relief for associated subjective ear symptoms.
- While audiological and vestibular issues in TMJ patients are often independent, a causal link between TMJ dysfunction and cochlear defects is plausible in select cases.
