[DPOAE otoemission in patients with tinnitus and normal hearing].
Otolaryngol Pol. 2003; 57(6):905-10.OP

Abstract

The goal of our study was analysis of characteristic interrogation, audiometry and distortion products otoacoustic emission in patients with normal hearing and complaining of tinnitus. We examined the group of 24 ill patients with hearing threshold up till 25 dB HL and with tinnitus and the control group of 18 with no audiological complains. All the patients were made tonal audiometry and the discomfort level as well as tinnitus frequency and intensity were evaluated. For each ear separately, we examined DPAOE of DP-gram function with resolving power of half the octave and the fine structure on the level of stimulation L1 = L2 = 70 dB. In the group of patients average time of tinnitus was 1.5 year. Average hearing threshold in patients with tinnitus was 18 dB HL for air conduction and 11 dB HL for bone conduction, average discomfort threshold--93 dB HL. In the control group hearing threshold was comparatively 16 dB and 10 dB HL and average discomfort threshold--95 dB HL. In the tinnitus group 8 patients (21%) complained of hyperacusis. The differences between the two groups in DP-gram were observed mainly in high frequencies (higher than 3000 Hz). In DP-gram fine structure in the group of patients with tinnitus we noted wider span of otoemission decreases (over the octave) compared to control group. In the tinnitus group among 20 examined ears with decreases of otoacoustic emission DP--fine structure only in 6 patients (30%) the frequency of tinnitus given by the patient was overlapping with the frequency for which decreases of otoemission were observed. In both groups we observed decreases of DPOAE for some frequencies but in the patients with tinnitus we noticed the lack of otoacoustic emission in wider span of frequencies, mainly in higher frequencies compared to controls.
