Abstract
Objective To explore the clinical characteristics of the distort product otoacoustic emission( DPOAE )in the tinnitus patients with normal hearing capability and its applied value. Methods DPOAE test was held in 160 tinnitus patients with the normal hearing capability and 120 healthy controls with the normal hearing capability and no tinnitus symptoms. The results were compared between two groups. The tinnitus patients were given nerve-nourishing medicine and vasodilator medicine for consecutive 3 weeks and then DPOAE test was performed again. The results before and after treatment were compared. Results In tinnitus group, the incidence of DPOAE in each frequency was significantly lower than that in healthy controls( P ＜0. 05 ). After the treatment, the DPOAE reacting amplitudes in high frequency were obviously improved in the tinnitus patients( P ＜ 0. 05 ). Conclusion The occurrence of the tinnitus may be relevant to the cochlear outer hair cell early injury-induced high frequency hearing loss, and DPOAE test can reflect the early stage cochlear injury and act as an objective method for detecting the tinnitus.关键词
