兒童人工耳蝸術(shù)后聽(tīng)覺(jué)言語(yǔ)發(fā)育影響因素及蝸內(nèi)電極位置的研究

摘要：

人工耳蝸術(shù)是兒童聽(tīng)力障礙的有效治療方法之一，但是其術(shù)后聽(tīng)覺(jué)言語(yǔ)發(fā)育的影響因素及蝸內(nèi)電極位置對(duì)效果的影響仍不清楚。本文對(duì)近年來(lái)有關(guān)該問(wèn)題的研究進(jìn)行了綜述和分析，認(rèn)為術(shù)前聽(tīng)力水平、年齡、語(yǔ)言環(huán)境等因素均會(huì)影響術(shù)后成功率和言語(yǔ)處理能力，而蝸內(nèi)電極位置的選擇根據(jù)兒童的聽(tīng)力狀況和術(shù)前聽(tīng)覺(jué)神經(jīng)的狀態(tài)進(jìn)行選擇，對(duì)于蝸神經(jīng)保護(hù)以及電極固定和穩(wěn)定性有重要影響。

Introduction:

兒童聽(tīng)力障礙是一種常見(jiàn)的兒童疾病，嚴(yán)重影響了兒童的言語(yǔ)發(fā)展和學(xué)習(xí)能力。人工耳蝸術(shù)是目前最有效的聽(tīng)力重建方法之一，其通過(guò)將植入人工耳蝸設(shè)備來(lái)刺激耳蝸神經(jīng)實(shí)現(xiàn)了聽(tīng)覺(jué)功能的恢復(fù)。然而，術(shù)后的聽(tīng)覺(jué)言語(yǔ)發(fā)育與以往聽(tīng)力狀態(tài)、手術(shù)技術(shù)、神經(jīng)退化程度和語(yǔ)言環(huán)境等多種因素有關(guān)。因此，本文旨在對(duì)兒童人工耳蝸術(shù)后聽(tīng)覺(jué)言語(yǔ)發(fā)育影響因素及蝸內(nèi)電極位置進(jìn)行深入研究和探討。
