摘要
目的探讨应用客观检测方法评价人工耳蜗植入患者术后听觉传导功能并指导术后调试的可行性。方法对39名人工耳蜗植入者分别选取第3、10、20电极,进行电诱发听性脑干反应(electric allyevok edaudito rybrainstem responses,EABR)、神经反应遥测(neuralresponset elemetry,NRT)、电刺激镫骨肌反射(electricall yevokedstap ediusresponses,ESR)检测及主观心理物理测试,测定EABR、电诱发听神经复合动作电位(electricallyevokedcompoundactionpotentials,ECAP)、ESR阈值、主观阈值(T-levels)和主观最大舒适强度(C-levels),分别对EABR、ECAP阈值与主观阈值,ESR阈值与主观最大舒适强度进行相关性研究。结果EABR平均阈值分别为158.63±10.86、159.71±11.17、152.92±10.82电流级(currentlevel,CL);ECAP平均阈值分别为188.71±15.19、194.61±10.21、185.07±11.52CL;ESR平均阈值分别为210.10±16.16、209.81±14.24、204.55±12.90CL。EABR阈值与主观阈值间、ESR阈值与最大舒适强度间显著相关(P<0.01);ECAP阈值与主观阈值间无显著相关性(P>0.05)。结论EABR是判断人工耳蜗植入者听觉传导功能的有效客观方法;EABR和ESR阈值的测定可协助判断人工耳蜗植入者的主观阈值和最大舒适强度。
Objective Electrically evoked auditory brainstem responses （EABR）,neural response telemetry（NRT）and electrically evoked stapedius responses （ESR） were used in cochlear implant （CI） users to investiqate the feasibility of determining the function of auditory conducting system and affiliating the CI device, Methods EABR, NRT and ESR were recorded in electrodes No. 3, 10, 20 of 39 cochlear implant users to detect the objective thresholds, Subjective perceptual measures were erformed at the same time in which perceptual thresholds （T- levels） and maximum comfort levels （C - levels） were measured. For each electrode, correlation between EABR, ECAP thresholds and T - levels, correlation between ESR thresholds and C - levels were studied using linear regression analysis. ReSultS Average thresholds of EABR measured in electrodes No. 3, 10, 20 were 158.63 ± 10. 86,159.71 ± 11.17,152.92 ±10.82 current level （CL） respectively;average thresholds of ECAP were 188.71 ±15.19,194.61 ±10.21,185.07 ±11.52 CL; average thresholds of ESR were 210.10 ±16.16,209.81 ±14.24,204.55 ±12.90 CL respectively. There was strong correlation between EABR thresholds and T - levels （ P 〈 0.01 ）, between ESR thresholds and C - levels （ P 〈 0.01 ）. No correlation was found between ECAP thresholds and T - levels （ P 〉 0.05）. Conclusion EABR is a reliable objective technique in evaluating the function of auditory conducting system in cochlear implant users. Detecting the objective thresholds of EABR and ESR can provide useful information in acquiring the T- levels and C- levels in cochlear implant users.
