【摘要】：目的：先天性極重度感音神經(jīng)性耳聾的聾兒在接受人工耳蝸植入（cochlearimplantation，CI）術(shù)后，應用聲場測試各純音頻率的聽閾值，評估聽覺能力。 方法：極重度感音神經(jīng)性耳聾并接受CI的48例患兒，，男33例，女15例。大前庭水管綜合征（large vestibular aqueduct syndrome，LVAS）10例。對48例患兒根據(jù)年齡分組，再將48例患兒根據(jù)內(nèi)耳正常發(fā)育及內(nèi)耳畸形之一的LVAS分組，應用聲場技術(shù)對上述患兒就250Hz、500Hz、1000Hz、2000Hz、4000Hz各純音頻率測試聽閾值及進行聽覺評估。統(tǒng)計方法：使用SPSS16.0統(tǒng)計學軟件對資料進行分析，計量資料采用均數(shù)±標準差（X±S）表示。采用兩獨立樣本t檢驗，P＜0.05有統(tǒng)計學意義。 結(jié)果：CI術(shù)后聲場測試≤3歲組250Hz聽閾值（29.38±9.24）dB；500Hz聽閾值（28.33±7.02）dB；1000Hz聽閾值（37.29±7.22）dB；2000Hz聽閾值（49.38±5.38）dB較3-6歲組｛（39.58±11.60）dB、（37.71±6.59）dB、（43.96±8.34）dB、（55.21±6.16）dB｝閾值均較低（P0.05）。在4000Hz頻率≤3歲組聽閾值（59.58±10.31）dB與3-6歲組聽閾值（62.08±9.43）dB間無統(tǒng)計學意義（P＞0.05）。CI術(shù)后正常內(nèi)耳發(fā)育組1000Hz聽閾值（51.00±6.99）dB較LVAS組1000Hz聽閾值（62.00±8.88）dB較低（P0.05）。CI術(shù)后正常內(nèi)耳發(fā)育組250Hz聽閾值（34.5±10.39）dB；500Hz聽閾值（42.00±10.33）dB；2000Hz聽閾值（59.50±8.64）dB；4000Hz聽閾值（69.50±4.97）dB較LVAS組｛（35.00±5.27）dB、（50.50±10.66）dB、（62.50±7.55）dB、（73.00±6.75）dB｝閾值均無統(tǒng)計學意義（P＞0.05）。 結(jié)論：應用聲場測試得到的各純音頻率的聽閾值評估CI術(shù)后聾兒的聽覺康復效果，是可行的；對該類患兒的聽覺及言語康復有較大的臨床指導意義。
[Abstract]:Aim: to evaluate the hearing ability of deaf children with congenital very severe sensorineural deafness after cochlear implantation. Methods: there were 48 children with severe sensorineural hearing loss and CI, including 33 males and 15 females. Large vestibular aqueduct syndrome in 10 patients with large vestibular aqueduct syndrome. According to age, 48 children were divided into four groups according to normal development of inner ear and LVAS of one of inner ear malformations. Sound field technique was used to test the hearing threshold and auditory evaluation of 250Hz ~ 500Hz ~ 500Hz ~ 1000Hz ~ 1000Hz ~ 2000Hz pure tone frequency. Statistical methods: the data were analyzed by SPSS16.0 software, and the mean 鹵standard deviation (X 鹵S) was used to measure the data. T test with two independent samples had statistical significance (P < 0.05). Results the auditory threshold of 250Hz was 29.38 鹵9.24dB1 500Hz and 28.33 鹵7.02dB1000Hz in the group of 鈮
