Abstract

OAE testing is more sensitive in the detection of the early onset of cochlear pathologies before a change in hearing thresholds. In the development of cochlear hair cells in the foetus human blood group antigens were involved. The present study is aimed to investigate the effect of blood group on evoked otoacoustic emissions amongAim: young adults in the Indian context. A total of 120 normal young adults of age 18 – 30 years were selected and groupedMethod: according to the ABO system of blood group, each consists of 30 participants and recorded both DPOAE and TEOAE. Results: The DPOAE and TEOAE amplitude showed signicant difference across frequencies and ears which do not follow a uniform pattern of signicance in all blood groups indicating no effect of blood group in OAE amplitude. The present studyConclusion: revealed no effect of blood group over evoked otoacoustic emission, though the results report a signicant difference among the majority of the test frequencies which is not uniform indicating any inuence, and this opens the possibility of other factors inuencing the OAE response.
