A cochlear implant (CI) can restore hearing in patients with profound sensorineural hearing loss by direct electrical stimulation of the auditory nerve. Therefore, the viability of the auditory nerve is vitally important in successful hearing recovery. However, the nerve typically degenerates following cochlear hair cell loss, and the amount of degeneration may considerably differ between the two ears, also in patients with bilateral deafness. A measure that reflects the nerve's condition would help to assess the best of both nerves and decide accordingly which ear should be implanted for optimal benefit from a CI. Diffusion tensor MRI (DTI) may provide such a measure, by allowing noninvasive investigations of the nerve's microstructure. In this pilot study, we show the first use of DTI to image the auditory nerve in five normal-hearing subjects and five patients with long-term profound single-sided sensorineural hearing loss. A specialized acquisition protocol was designed ...

Objective: To report on surgical complications arising post-operatively in 104 patients undergoing cochlear implantation surgery using the suprameatal approach (SMA). Second, to examine the advantages and disadvantages of the SMA technique compared with the classic mastoidectomy using the posterior tympanotomy approach. Study Design: Retrospective study assessing surgical complications in deaf adults and children undergoing cochlear implantation. Setting: Tertiary referral center
