[Nucleus 24 contour in patients with sound sensorineural hearing loss].
OBJECTIVE
To report the surgery and the postoperative outcomes with Nucleus 24 Contour electrode array in patients suffered from profound sensorineural hearing loss.


METHODS
The surgery and postoperative current level making electrical hearing are compared between the group with Nucleus 24 contour and the group with Nucleus 24 M.


RESULTS
Among the 82 cases,32 electrodes were inserted in 81 cases, 28 electrodes in 1 case. The intraoperative small CSF flowing occurred in 31 cases and no CSF flowing occurred in 2 cases. The slight postoperative complications of the surgeries occurred in seven patients. The postoperative NRT threshold of the group with Nucleus 24 Contour was lower than the group with Nucleus 24M. There was a statistically significant difference in the 1th channel about the NRT threshold (P < 0.05).


CONCLUSIONS
Using Nucleus 24 Contour makes the surgery esaier than using Nucleus 24 M, minimizes the introcochlear trauma during insertion and reduces the current level producing electrical hearing. The Nucleus 24 Contour is a new, safe and effective implantation to the patients with profound sensorineural hearing loss.
