RESUMO
Objective To investigate the prevalence, etiology, rehabilitation demands and service condition of hearing disorders based on the whole population in Jilin Province, China. Methods Using the probability proportion to size (PPS) sampling, 9246 (93.3%) out of 9909 residents sampled form 36 counties were targeted for investigation from August, 2014 to January, 2015, followed the WHO Ear and Hearing Disorders Survey Protocol. The hearing loss and disability were classified as WHO recommended and Classification and Grading Criteria of Disability (GB/T 26341-2010). Results The standardized prevalence of hearing loss and disability was 16.41%and 4.78%, re-spectively. Age, sex, residence, occupation and marriage status, education level and household income were significantly associated with hearing loss prevalence, while nationality was not. The main etiologies included non-infectious disease (47.33%), ear disease (14.17%), un-known causation (13.89%), and noise (8.59%). Among all people with hearing loss, those who accepted intervention service accounted for 11.02%. Among all people with hearing disability, those who used hearing aids accounted for 5.58%, and 0.67%used artificial cochlea. Con-clusion Demographics and socioeconomic factors are significantly associated with the prevalence of hearing loss. The main etiology con-tains non-infectious disease, ear disease and noise. Both the rate of service utilization among people with hearing loss and the rate of adopt-ing hearing aids among people with hearing disability are low. It is needed to do more in prevention and rehabilitation of hearing impairment.
RESUMO
<p><b>OBJECTIVE</b>To investigate the basic factors of the progress amplitude of hearing and speech rehabilitation effect of preschool deaf children with cochlear implants, and provide guidance for the improvement and optimization of rehabilitation strategies.</p><p><b>METHOD</b>Using the standard hearing and language assessment tools, tracked and evaluated 1 422 CI preschool deaf children for a period of one year, and calculated the effect of hearing and speech rehabilitation, carried out the correlation analysis and variance analysis among different grouping variables.</p><p><b>RESULT</b>(1) There was a negative correlation (P<0.01) between the rehabilitation effect and cochlear implantation age, existed the different degree of positive correlation (P<0.01) between the rehabilitation effect and parents cultural level, but no correlation between the rehabilitation effect and parents hearing status.(2) Father's education level, in comparison to mother's education level, had greater impact on the children rehabilitation effect.(3)There was positive correlation(r=0.689, P<0.01) between the progress amplitude of hearing and speech rehabilitation effect. (4) The progress amplitude of auditory and language rehabilitation effect of 2-3 years old group was the highest value(the progress amplitude of hearing and speech recognition rate reached 77.5%, the progress amplitude of language age progress rate reached 2.02 years old), and there were significant differences (P<0.05) between over 3 years old groups.</p><p><b>CONCLUSIONS</b>(1) To expect the better progress amplitude of rehabilitation effect, cochlear implant age should not be more than 3 years old. (2) Father's effect in the process of rehabilitation is more helpful for deaf children's learning enthusiasms.</p>

Objective Base on the neighborhood activation model(NAM), to develop the Mandarin monosyllable lexical neighborhood test(M-LNT-monosyllable), which is expected to be useful for evaluating speech perception performance in children with hearing loss. Methods Test items were based on the lexical characteristics of word frequency and neighborhood density which addressed in the neighborhood activation model (NAM). M-LNT -monosyllable consisted of two parts: Lexically "easy" words with high word frequency, which were low phonemically similar to the target word and lexically "hard" words with low word frequency, which were high phonemically similar to the target word. 34 children of 3~5 year old with normal hearing were choosed as subjects to verify easy word and hard word lists. Results 1 979 words for children contained 487 easy words and 419 hard words. Three easy word lists and three hard word lists were developed to estimate the performance of word recognition among normal- hearing children. There were no differences among scores of three easy words lists(P>0.05), and no difference among scores of three hard words lists(P>0.05). But there were significant differences between scores of easy and hard words lists(P<0.01). Conclusion The development of the lexicon was affected by the lexical characteristics. Normal-hearing children with some lexical techniques were affected by the lexical characteristics when they recognized the spoken words, but children with less lexical technique didn't show the same result because the recognition was processed on the phonetic level.
RESUMO
Objective To know the position and shape of implanted electrode array with plain X-ray after cochlear implantation. Methods According to the Cochlear View developed by Xu plain X-ray was taken postoperatively to obtain the best view of electrode array. Results The Medical imaging of plain X- ray taken before switching on or following the concerning of the performance could assist in the detection of electrode arrays in improper position, partial insertion or bending inside the cochlea. It helped audiologists to make decisions to switch off affected electrodes for the optimization of the program, if functioning electrodes were insufficient and recipients failed. Conclusion It is recommended to conduct post-operative X-ray examination routinely for cochlear implant recipients. Audiologists should be able to use medical imaging to identify the position of intra-cochlear electrodes and apply the information to guide the mapping work.
RESUMO
OBJECTIVE To analyze the phonetic acquisition and speech articulation in deaf children. METHODS The speech articulation test and consonant and vowel identification test were performed with 30 children. RESULTS The consonants /b.p.d.t.m.l/ were the easiest to learn. Of the vowels, single vowels received the highest score. CONCLUSION The results of the consonant identification test, listed from easy to difficult, were /b.p.d.t.m.l/,/h.f.s.x.n/,/c.z.zh.ch.j.q.r/. The results of the vowel test, listed in the same order, were single, duplicate and nasal.
RESUMO
@#ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

RESUMO
<p><b>OBJECTIVE</b>To explore the prevalence of vision, mental, audibility, language, psychiatry, extremity, and influence factors in the 0 - 7 year olds.</p><p><b>METHODS</b>A total number of 77,727 0 - 7 year old children living in Shenzhen city were tested with tree phase screening under the Chinese standard of evaluation in disabilities.</p><p><b>RESULTS</b>The prevalence of all disabilities was 5.59 per thousand (adjusted rate was 8.49 per thousand with a false negative of 3.1 per thousand ). The prevalence of mental disease was the highest (1.88 per thousand, with adjusted rate 3.43 per thousand ), the prevalence of language disability was 1.88 per thousand (including retarded language development, with adjusted rate 3.43 per thousand ). The prevalence rates of psychiatry, extremity and audibility disability were 1.59 per thousand, 1.56 per thousand, 1.11 per thousand respectively with of vision the lowest (0.37 per thousand ). The prevalence of all disabilities, audibility, language and mental was on the increase with age. The difference was statistically significant. Among all different age groups regarding psychiatric disease, the highest fell in the 2 - 4 year olds. The prevalence of extremity was not statistically different among age groups. The suspected agents of disease which occurred before or during pregnancy took up 45.7%.</p><p><b>CONCLUSION</b>The prevalence of six kinds disabilities in Shenzhen was about 10 per thousand lower than that of the samples of the nation in 1989, but two times higher than that of similar studies in Japan. The prevalence rates of language and psychiatric disease were higher than that of the nation in 1989. The causation should be further studied.</p>

ObjectiveTo search for the optimum external masking time and tonal models for patients with tinnitus.MethodsTwenty-seven patients with cochlear tinnitus were selected respectively from three different out-patients departments and divided into three groups. Nine patients in every group were treated with different masking parameters according to factorial design which had three masking noises, i.e. narrow band noise (NBN), wide band noise (WBN), speech noise (SN),and three masking time ranges, i.e. 15,30,45 minutes. The results before and after treatment were compared and analysed with analysis of variance (ANOVA). ResultsThe treatment effect when masking for 15 minutes was worse than that for 30,45 minutes, but there was no difference between 30 and 45 minutes. The NBN had the best effect when tinnitus signal was single, the WBN was effective for tinnitus with multiple sounds. ConclusionNBN or WBN masking for 30 minutes showed better therapeutic effect.
