Abstract:

SUMMARY - There is two techniques for insertion of the electrodes of the cochlear implantation (IC): chocleostomy via or window round via (JR). Objective: To compare the telemetry of neural reply (NRT) in postoperative the immediate one being verified if has differences in the stimulation of the auditory nerve between these two techniques. Methods: Prospective and transversal. 23 patients had been evaluated. Six submitted to the surgery saw chocleostomy and seventeen JR via. Results: Comparison of the average units of chain (UCM) for acute sounds: JR via with average of 190.4 (±29.2) and saw chocleostomy 187,8 (±32.7), p 0,71. Comparison of the UCM for intermediate sounds: It saw JR, average of 192.5 (±22) and saw chocleostomy 178,5 (±18.5), p 0,23. Comparison of the UCM for serious sounds: JR via, average of 183.3 (±25) and saw chocleostomy 163,8 (±19.3), p 0,19. Conclusion: This study did not show difference in the capitation of the potential of action of the distal portion of the auditory nerve in using patients of the implantation to cochlear multichannel submitted the chocleostomy via or JR via surgery, using the proper implantation to elicit the stimulation and to record the answers. Therefore both the techniques stimulate in equal way the nerve to cochlear, and established in this also concludes that, to carry through the implantation to cochlear chocleostomy via or JR via is a choice that depends on the surgical experience and option of the surgeon.
