Abstract


Background and Aim: Sound processors in cochlear implant (CI) cannot encode low frequency information and they discard much of the temporal fine structure required to perceive fundamental frequency (F0). Hearing aids can transmit low frequency information are very important for pitch perception and provide many advantages for users. The aim of this study was to compare aural/oral performance bimodal cochlear implants with unilateral ones in children using parents' evaluation of children’s aural/oral performance (PEACH) questionnaire.
Methods: Twenty children with unilateral cochlear implant and twenty children with bimodal cochlear implants were selected for this study. Of the 40 participants, 23 had a cochlear device, 10 a Med-El device, and 7 patients wore an Advanced Bionics device. Bimodal group had at least seven months of hearing experience with digital hearing aid in non-implanted ear. In order to compare aural/oral performance in these groups, we used the PEACH questionnaire.
Results: In unilateral and bimodal groups, age of implantation, age of testing and hearing experience before CI use were not significantly different. There was significant difference in quiet score, noise score and total score between unilateral and bimodal groups (p<0.05).
Conclusion: In bimodal group, aural/oral performance was significantly improved in quiet and noise situations in comparison to unilateral group. This improvement is due to the advantage of binaural processing and low frequency information provided by hearing aid.
