Abstract:

Objective  To evaluate the modified cochlear view so as to access the appearance and accurate insertion depth of cochlear implantation.   Methods  21 patients, 30 days to 4 years of age, had both Xu′s X-ray pictures and modified X-ray pictures taken. The number of electrodes in the cochlear canal was counted, and then the number of electrodes by X-ray picture and by operation were statistically dealt with by a t-test. ResultsInserted artificial electrodes could be discerned on both the cochlear view and the modified cochlear view. There was no difference among the data from operation and plan radiographs. Conclusion  The modified cochlear view is simple and comfortable for patients younger than 4 years, and can show the precise appearance and accurate insertion depth of the cochlear implantation.
