Objective To analyze the effect of hearing rehabilitation and the changes in life of quality after cochlear implantation in elderly patients with age-related hearing loss.Methods The audiology,speech function and quality of life of 31 patients with age-related hearing loss undergoing cochlear implantation were evaluated and compared.Audiology was evaluated using hearing aid threshold and speech perception was evaluated using word recognition rate(WRS)before surgery,at 6 and 12 months after cochlear implant activation.The quality of life was assessed using the Nijmegen cochlear implant questionnaire(NCIQ)before surgery and at 12 months after activation.Results A total of 31 patients were enrolled in this study.The hearing aid thresholds before surgery,at 6 and 12 months after activation were(62.55±3.69),(46.58±5.14)and(38.68±4.26)dBHL,respectively,and the differences were statistically significant(P＜0.05).The monosyllabic word recognition rates before surgery,at 6 and 12 months after activation were(9.55±5.81)% ,(54.77±8.90)% and(68.52±7.21)% ,respectively,the difference were statistically significant(P＜0.05).The recognition rates of disyllabic word were(19.87±9.72)% ,(64.00±6.53)% ,and(74.26±6.79)% ,and the differences were statistically significant(P＜0.05).The recognition rates for short sentence were(28.00±10.58)% ,(68.52±7.78)% ,and(77.61±8.59)% ,and the differences were also statistically significant(P＜0.05).The total scores of NCIQ before surgery and at 12 months after activation were 35.90±5.80 and 65.16±8.18,respectively,with statistically significant difference(P＜0.05).Conclusions Cochlear implantation can improve speech perception and the quality of life in patients with age-related hearing loss.Cochlear implantation can be chosen for elderly patients with severe or more hearing loss if the hearing aid is not effective.
