Distortion product otoacoustic emissions in diabetics with normal hearing.
In 18 diabetic patients with normal hearing, distortion product otoacoustic emissions (DPOAEs) were measured. DPOAEs' amplitude and latency were analysed and compared with the data obtained from non-diabetic controls. The mean amplitude and latency were lower in diabetics than in controls. These results suggested that diabetes mellitus may induce the functional alteration of outer hair cells even in the normal hearing group. Further studies should be performed to evaluate the predictability of DPOAEs in hearing loss of the diabetic patient.
