To determine the relationship between temporomandibular joint dysfunction (TMJD) and tinnitus in Peruvian adult patients.
This observational and cross-sectional study was conducted between April and May 2023, including 76 adult patients from the Otorhinolaryngology Service of Víctor Lazarte Echegaray Essalud Hospital in Trujillo (Peru). The intra- and inter-rater reliability was determined for the clinical measurement of TMJD, obtaining Kappa values above 0.995. To diagnose tinnitus, we worked with a doctor specializing in otolaryngology. Chi-square test and logistic regression were used to analyze results, considering a significance level of p<0.05.
A relationship was found between TMJD and tinnitus (p=0.022), increasing the frequency of this disorder as temporomandibular involvement was higher (p=0.043). There was no relation between these disorders according to gender and age, nor in hypertensive patients (p=0.131) or patients suffering from migraine (p=0.147); however, a relationship was found between TMJD and tinnitus in patients with hearing loss (p=0.046).
TMJD is associated with tinnitus in otorhinolaryngological and hypoacusis patients. However, in hypertensive and migraine patients, and according to gender and age, no relation was found between those disorders.
