[Analysis of factors effecting satisfaction of cochlear implants in prelingually deafened adolescents].
OBJECTIVE
By means of investigating how the benefit and the influence factors are for the pre-lingual deaf adolescents who received cochlear implantation (CI) METHODS: A questionnaire survey was conducted among 30 prelingually deaf adolescents-cochlear implant recipients, aged 9 approximately 20, 15 of which began to use hearing aid before the age of 6, and 19 of which had received speech testing after the CI, and their families to understand the degree of satisfaction, anticipation of the outcome. Nine of the 15 patients who began to use hearing aid before the age of 6 communicated by the oral communication/labial reading model (oral group), and 10 of the other 15 patients who had not used hearing aid after the age of 6 mainly communicated by sign language (sign group).


RESULTS
The satisfaction score of the group with a hearing aid fitting history was 3.93 +/- 0.88, significantly higher than that of the group without a hearing aid fitting history (3.00 +/- 1.13, P < 0.05). The scores of speech production ability in vowel, consonant, single syllable, disyllable, trisyllable, and short sentence in the groups with and without a hearing aid fitting history were 76%/52%, 64%/45%, 71%/26%, 82%/96%, 68%/12%, and 49%/13% respectively (all P < 0.05), and there was no significant difference in the speech production ability in tone (P > 0.05) between these 2 groups. There were no significant differences in the total satisfaction degree, satisfaction degree in speech sound, and satisfaction degree in environmental sound between the oral group and sign group (all P > 0.05). The scores in vowel, consonant, single syllable, disyllable, trisyllable, short sentence, and tone of the oral and sign group were 74%, 60%, 64%, 61%, 57%, 43%, 27% and 43%, 39%, 26%, 26%, 20%, 6%, 5% respectively (all P > 0.01). The anticipation of the patient and the parents about outcome before implantation was negatively correlated with the satisfaction degree after implantation, (gamma = -0.479, P < 0.05).


CONCLUSIONS
Cochlear implantation benefits greatly the deaf adolescent; however, it is necessary to establish a specific evaluation system according to recipients' needs.
