Abstract OBJECTIVE: To investigate the contralateral suppressions of transient evoked otoacoustic emissions (TEOAE) in diabetes mellitus patients with normal hearing. METHOD: The pure tone audiometry, acoustic immittance and TEOAE tests were performed in 30 diabetes mellitus patients with normal hearing and 30 healthy controls. The efferent system functions were evaluated by contralateral suppression of TEOAE. RESULT: There were no significant differences of pure tone thresholds and amplitudes of TEOAE between the two groups. The contralateral suppressions of TEOAE in diabetes mellitus patients were significantly lower than that in controls (P<0.05 at 2000 and 4000 Hz respectively). CONCLUSION: The nerve functions of central nerve system can be damaged in diabetes mellitus patients with normal hearing.
