Abstract
Conclusion In conclusion, we used in this study Doppler ultrasonography and FMD to investigate the relationship between implant speech perception (as measured by single syllable performance scores) and cerebral blood flow instead of PET scan used in the past two decades. FMD and carotid Doppler measurements study appeared adequate to explore the benefits of cochlear implants. BMD was significantly correlated with Age, Duration of deafness, Total ICA Mean velocity and FMD in univariate analysis, but FMD was only showed significant positive correlation with BMD in Stepwise multiple liner regression analysis. from the ROC curve, cut-off score of FMD 1.8 could be used as a predictable marker for adult post-lingual CI candidate.
The correlation between FMD and BMD is also suggested that improvement of small vessel condition could change the hearing ability better in CI patients, and both continuous measurement of FMD and interventions for the maintenance of endothelial function might maintain their hearing ability for long time. This methods could then be used to predict outcome of implantation and to follow up the patients with a non-invasive way to improve auditory rehabilitation.
A complementary study must be performed with enlarging the number of normal subjects and implantees. This methods could then be used to predict outcome of implantation and to follow up the patients with a non-invasive way to improve auditory rehabilitation.
