Summary

The objective of this study is to examine whether ABO and Rhesus (Rh) blood group systems have an association with distortion product otoacoustic emission (DPOAE) and transient otoacoustic emission (TEOAE) amplitudes with the hypothesis of blood groups may affect hearing thresholds.

Detailed description

Many factors have a significant impact on otoacoustic emission (OAE) measurement and quality of analysis. Race, age and gender are among the non-pathological factors. To date there is clear data to demonstrate the association of blood types with OAEs. The aim of our research is to investigate the relation of different blood groups (ABO) and Rh factors on transient evoked OAE and distortion product OAE amplitudes and inner ear potentials, differences between ears and to contribute to the limited literature on cochlear hearing loss susceptibility and blood groups with the hypothesis that blood groups may be associated with hearing thresholds.
