Abstract
Objective To evaluate the effect of MRI on assessing morphology of cochlea and cochlear nerve before cochear implantation. Methods One haundred and one patients with deafness were undergone the cochlea and cochlear nerve examination with MRI before cochlear implantation. Results The cochleas and cochlear nerves of 89 patients were in good status;cochlear malformation were found in 12 patients,4 of them accompanied with cochlear nerve malformation. Conclusion MRI should be routinely performed before cochlear implantation in order to know the morphological characterics of cochlea and cochlear nerve.
