Evaluation On The Hearing, Speech And Quality Of Life For Cases Received Cochlear Implant

Objective :Through the use of CAP – II(The Categories of Auditory Performance-II), SSQ –P(The Speech, Spatial and Qualities of Hearing Scale-Parents’ version), Cu HI –Qo L(Children using Hearing Implants Quality of Life) for auditory performance,speech behavior and quality of life of patients with prelingual hearing impairment to compare the rehabilitation effect between preoperative and postoperative and at the same time to figure out dose rehabilitation effect connected to the age.Methods: Mainly used for classification method is to devide 50 patients into two groups on the basis of before and 2.5 years after the implant. At the same time these 50 patients are divided on the basis of the age received the surgery, i.e. group received the surgery before 6(1.0-5.9) years old and group B received the therapy after this age(6.0-10.9). Their auditory performance, speech behavior and quality of life were all evaluated. In the results of preoperative audiological examinations, all the children are severe to extremely severe sensorineural deafness. From the imageological diagnosis, there are 2 cases of bilateral chronic otitis media, 1 case of unilateral chronic otitis media, 3 cases of bilateral large vestibular aqueduct syndrome, 2 cases of unilateral large vestibular aqueduct, 9 cases with cerebral white matter lesions, 3 cases with the inner ear malformation. Patients with suspected mental developmental abnormalities, abnormal behavior and psychological behavior are excluded from the scope of this research. Operations are completed by the same physician. All the patients are implanted in cochlear 90 k type of the United States. All the patients boot debugging after a month. There are no serious complications occurred intraoperatively and postoperativelyResults: There were statistical difference between two kinds of classification method of CAP-II. In the study of SSQ –P and Cu HI – Qo L, there was no statistical difference in wellbeing and happiness before and 3 years after the implant, also there was no statistical difference in parental stress between two age groups. In addition to the above two, the rest all have statistical significance.Conclusion : After the implant, postoperative auditory performance, speech behavior and quality of life all had improvement than the surgery before and the smaller the age, the better the performance. Cochlear implantation can help children to regain the hearing, also rehabilitation is an important process. Only through hearing rehabilitation training can help children gain confidence, have good communication with others and be adaptable to social life.
