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

Introduction:

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