Objectives: Present study aimed to evaluate the effect of cochlear implantation on mechanoacoustical property of ME by studying resonant frequency using MFT. Design: Cross sectional study. Study Sample: Total of 30 candidates participated in study, were divided into two groups. Group I included 15 cochlear implant recipients with age range of 3.5 to 10 years and group II included cochlear implant candidates with age range of 3 to 8 years. Results: Descriptive analysis was carried out to find out the mean and standard deviation for resonant frequency (f0) in both groups. In present study, the resonance frequency of middle ear was increased significantly in implant ear compare to all three non implanted ear i.e. non-implanted ears of group I and both the non-implanted ears of group II. Conclusion: The findings of the present study should be interpreted cautiously as it has been done on a small data. Further grouping of patients according to the duration of cochlear implant use and type of electrode array would enable to look for any correlation between them and the resonance frequency will provide a better picture for implementation of information in cochlear implant population.
