双侧人工耳蜗植入研究进展

人工耳蜗植入目前是极重度感音神经性聋的最有效的治疗方法,双耳听力植入开始于上世纪90年代。尽管其存在费用、手术风险、患者远期期待、双侧植入设备整合等问题,双侧耳蜗植入越来越被广为接受,被耳科专家所推荐。相比单侧植入,双耳植入可显著提高声音定位能力,减小头影效应,明显改善在安静和噪声下的听力和言语理解能力,有助于获得更自然的声音感受,促进听觉言语和音乐欣赏能力的发展,更快的重建言语功能。双侧耳蜗植入带来的听觉刺激可以更好的促进听觉通路和皮层的协调发育。

Progress in bilateral cochlear implant research

Cochlear implantation(CI)is currently the most effective treatment for profound sensorineural hea ring loss.The first bila teral CIs were performed in the 1990 s.Despite the cost,surgical risk,patient expectation,and integration of bilateral equipment,bilateral CI has been widely accepted by patients and recommended by otologists.Compared with unilateral CI,bilateral CI can significantly enhance sound source positioning and minimize the head shadow effect.Hearing function and linguistic perception would be improved in quiet and noisy environments,potentially promoting linguistic and musical skill,and accelerating speech rehabilitation.Biauricular stimulation could also coordinate develop-ment of the acoustic pathway and cortex.
