title: [The clinical application of objective hearing monitoring technology in cochlear implants].
abstract: OBJECTIVE
  Compare the clinical characteristics and application value between elcetrically evoked stapedius responses and neural response telemetry.
  
  
  METHODS
  Select number 1, 7, 11, 17, 22 electrodes from 21 cochlear implanting nucleus 24R cochlear implants, using NRT3.0 software provided by Cochlear corporation to test the threshold of elcetrically evoked stapedius responses and neural response telemetry during operation and subjective psychological physical test after operation repectively named elcetrically evoked stapedius responses threshold, electrically evokded compound aciton potentials threshold, and T-levels. Respectively study the correlations of ESRT, ECAP threshold, and T-levels.
  
  
  RESULTS
  The detection rates of ESRT, NRT, and T-levels were 96.19%, 93.33%, 100%. The mean thresholds of ESRT were 206.61 +/- 10. 74, 208.48 +/- 13.64, 205.52 +/- 14. 63, 203.76 +/- 12.97, 199.50 +/- 11.19; The mean thresholds of NRT were 184.11 +/- 6.35, 188.55 +/- 11.70, 187.00 +/- 12.29, 181.85 +/- 13.22, 179.00 +/- 10.50; The mean thresholds of T levels were 145.48 +/- 18.66, 148.62 +/- 8.22, 146.62 +/- 18.08, 142.52 +/- 13.11, 140.33 +/- 13.68. The mean thresholds of ESRT in each electrode were rather greater than that of T-levels. There is a high degree of consistency in the mean thresholds of ES RT, NRT and T-levels. The test time, test means, unilaterally detection rate during operation, ESR is better than NRT. All the electrodes were set as observation objects, the correlation of ESRT and NRT is 0.69, the correlation of NRT and T is 0.62, and the correlation of ESRT and T is 0.39.
  
  
  CONCLUSIONS
  The application of elcetrically evoked stapedius responses and neural response telemetry during operation can rapidly estimate wether the implant is in good condition and the pathway is normal. Rather than neural response telemetry, elcetrically evoked stapedi us responses is more flexible, convienient, accurate and visual, while it is more objective superiority after operation especially for young children for the former detector.
