      The relationship of high-frequency distortion product otoacoustic emission (DPOAE) values with hematological parameters in tinnitus patients

      In this study, we aimed to investigate whether there is any positive or negative correlation between high-frequency distortion product otoacoustic emission (DPOAE) values and mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR) in tinnitus patients.

      The study was performed with 52 volunteers (27 females, 25 males) aged between 35 and 50 years who presented with tinnitus to the otolaryngology outpatient clinic of a tertiary care center. Pure voice audiometric examination, DPOAE measurement, complete blood count values of the study participants were examined.

      In both ears, a significant and negative correlation was observed between 4000 and 8000 Hz airway and 4000 Hz bone conduction pathways with NLR rates (p < 0.05). A statistically significant relationship was found between the bone conduction pathway PTA and discrimination values for both ears and NLR s (p < 0.05). A positive correlation was detected between NLRs and DPOAE measurements recorded at 4444 Hz, 5000 Hz, 8000 Hz, 8889 Hz, 10,000 Hz and 11,429 Hz frequencies in the right and 4444 Hz, 5000 Hz, 6154 Hz, 8000 Hz, 10,000 Hz and 11,429 Hz frequencies in the left ears, respectively (p < 0.05).

      We concluded that there is a significant correlation between high-frequency pure tone audiometry measurements and high frequency DPOAE measurements and NLR. Further studies are needed to determine the utility of NLR as a marker for the recognition and follow-up of hearing loss in patients with tinnitus.
