Abstract:

Introduction: Many hipotheses have been arisen to explain the correlation between auditory symptoms and temporomandibular joint dysfunction (TMJD) since Costen´s studies in 1936. However, just a few articles have studied the identification of auditory signals that come along with the TMJD. Aim: The objective of this work was the analysis between the symptoms referred by the patient having TMJD and the real implications of the auditory system. Material and method: From the forty four patients who were assisted, just 10 fulfilled the selection criteria, and were evaluated before and after odontological treatment through pure tone audiometry, speech audiometry, timpanometry, acoustic reflex test and static compliance measures; besides that, all subjects underwent odontological and ENT examinations. Results: Before odontological treatment, results showed mild hearing loss in isolated frequencies (60%), type A timpanograms (40%), and normal acoustic reflex thresholds (50%). After the treatment the only relevant change noticed was in the static compliance measure (50%).
