Abstract

The purpose of this study was to investigate the possible connection between temporomandibular disorders (TMD) and cochlear nerve function. In this study, twenty healthy subjects and twenty TMD subjects with no otologic symptoms were selected and normality of conductive hearing function of middle ear transmission system was confirmed by impedance audiometry (Tympanograms and auditory stapedius reflexes) utilizing impedance meter (J. M. Morita Co.). Then, spontaneous otoacoustic emissions (SOAEs) were measured and analyzed utilizing GSI-60 DPOAE systems (Grason-Stadler Inc.). Theresults were as follows:<BR>ValuesofthepeakaverageofSOAEswere4.4±2.6dB SPL in healthy subjects and 7.3±4.5dB SPL in TMD subjects, and significant differences (p<0.05, Mann-Whitney U-test) were noted between the two groups.<BR>From the results, it was suggested that peak values (dB SPL) of SOAEs caused cochlear nerve are influenced by unusual trigeminal nerve excitation related temporomandibular disorders in TMD subjects.
