摘要

背景:感觉神经性听力损失(SNHL)是最常见的先天性感觉缺陷,每1000个活产婴儿中有1到3个的发病率。3岁前的听力剥夺会阻碍儿童的言语和语言习得,对儿童的教育和社会心理发展产生严重的负面影响。永久性重度到深度听力损失的金标准干预措施是人工耳蜗植入。人工耳蜗(CI);是一种绕过耳蜗的半植入式电子装置。目的:对40例语前耳聋患者进行观察性研究,了解语前耳聋的原因,评价术前操作,为语前人工耳蜗植入术制定理想的标准,评价人工耳蜗植入术的手术方式和效果。方法:对应聘者进行病史、全身健康检查、耳鼻喉科检查、听力学评估、CT和MRI扫描、心理特征等评估。行有限皮质乳突切除术。使用包括窝作为初始标志打开面部隐窝。通过镫骨下方约2mm的面隐窝可见圆窗壁龛。耳蜗造口术通过在耳蜗底侧圆窗膜的前部和下方钻孔而形成的耳蜗造口术然后将电极阵列小心地通过小孔插入耳蜗的中耳膜。进行电生理测试(神经反应遥测:NRT)来验证活动电极的正确放置。结果:其中男性22例(55%),女性18例(45%)。男女比例为1.2:1。植入时年龄分布为3.3±1.054(SD)。平均听力损失96.4±5.3(SD) dB,辅助听力图63.7±4.6(SD) dB。1.总体并发症达卡国立耳鼻喉科研究所副教授。注册主任,国家耳鼻喉科研究所,达卡。孟加拉国国家耳鼻喉科研究所助理教授。4 .达卡国家耳鼻喉科研究所医生。达卡国家耳鼻喉科研究所研究员。达卡国家耳鼻喉科研究所助理注册主任。通讯地址:Zakaria Sarker博士,达卡国家耳鼻喉科研究所副教授,手机号码:01819157287,E-mail: zakaria.sarker@ymail.com

Preoperative Evaluation and Surgical Outcome of Cochlear Implantation in NIENT
Background: Sensory neural hearing loss (SNHL) is the most common congenital sensory deficit, with an incidence of one to three per 1000 live births. Acoustic deprivation during the first 3 years of life can hinder speech and language acquisition with significant negative consequences on a child’s educational and psychosocial development. The gold standard intervention for permanent severe to profound hearing loss is cochlear implantation. Cochlear implant (CI); is a semi implantable electronic device that bypass the cochlea. Objectives: An observational study was carried out on 40 cases of pre-lingual deaf to find out the causes of pre-lingual deaf, to evaluate the preoperative procedures to set ideal criteria for pre -lingual cochlear implantation and to evaluate surgical procedure and outcome of cochlear implantations. Methods: Evaluation of the candidates included patient medical history, general health checkup, ENT examination, audiometric evaluation, CT and MRI scans, psychological profile of the candidate. A limited cortical mastoidectomy was performed. The facial recess was opened using the fossa of incudis as an initial landmark. The round window niche was visualized through the facial recess about 2 mm inferior to the stapes. A cochleostomy created by drilling over the basal turn of the cochlea anterior and inferior to the annulus of the round window membrane. The electrode array was then carefully inserted through the fenestra into the scala tympani of the cochlea. Electrophysiological testing (Neural Response Telemetry: NRT) was performed to verify the correct placement of active electrodes. Resulst: Among them 22 (55%) were male and 18 (45%) were female. Male female ratio was 1.2:1. Age distribution at implantation was 3.3±1.054(SD). Average hearing loss was 96.4±5.3(SD) dB and in aided audiogram was 63.7±4.6(SD) dB. Overall complications 1.
