Analysis On The Effect And Influencing Factors Of Cochlear Implant In Older Patients

Objective: By analyzing the influence of various factors on the postoperative effect of cochlear implant in older patients(more than 7 years old),the paper provides theoretical basis for improving rehabilitation effect and establishing scientific and correct rehabilitation concept.Methods: we select 53 patients(25 males and 28 females,31 cases post-verbal deafness and 22 cases pre-verbal deafness,age 7-69 years old)who underwent CI in the department of otolaryngology,the first affiliated hospital of China medical university from 2013 to 2019.These patients all were severe or extremely severe sensorineural deafness.Audiometry,speech recognition detection and questionnaire survey were conducted at 6 months and 24 months after cochlear implantation,and the results were statistically analyzed.Results: The results of univariate analysis showed that were significant differences in Audiometry and SIR among different implant age groups(P< 0.05).There were significant differences in the speech recognition rate of the two syllables and short sentences and the children’s quality of life in CuHIQol among the groups with different deafness characteristics(P<0.05).Monosyllabic and disyllabic results were significantly different in speech recognition rate between groups with different time of severe deafness(P< 0.05).There were significant differences in children’s quality of life in CAP,SIR,speech recognition and CuHIQol(P< 0.05).There were no statistically significant differences in hearing,speech and quality of life among groups with different causes of hearing loss,residual hearing and auditory patterns(P< 0.05).2.Multiple linear regression analysis showed that implantation age was significantly correlated with hearing threshold and SIR results(P< 0.05).The deafness of language was significantly correlated with the monosyllabic and disyllabic of speech recognition rate and the children’s quality of life in CuHIQol(P< 0.05).The time of severe deafness was significantly correlated with the speech recognition rate and CAP and SIR(P< 0.05).Hearing aid time was significantly correlated with children’s psychological outcomes in CAP,SIR,speech recognition and CuHIQol(P< 0.05).3.There were statistically significant differences in Audiometry,speech recognition rate,CAP,SIR,NCIQ and CuHIQol results between the short-term(6 months after CI)and long-term(24 months after CI)of older patients(P < 0.05),the long-term effect of hearing,speech and quality of life of older patients after CI was better than the short-term effect.Conclusion: 1.The younger the age of implantation,the better the postoperative auditory and verbal effects.2.The postoperative speech effect and children’s quality of life of the elderly patients with post-verbal deafness were better than pre-verbal deafness.3.The longer the duration of severe deafness in older patients,the worse the postoperative speech effect.4.The longer the preoperative hearing time of older patients,the better the postoperative auditory and verbal effects and children’s quality of life.5.The longer the postoperative recovery time of older patients,the better the effect of hearing and speech rehabilitation,and the better the quality of life.
