To learn the benefit of the unilateral profound sensorineural hearing loss patients wear bone conduction hearing aid BAHA.
Sixteen unilateral profound sensorineural hearing loss patients done BAHA aided pure tone test and speech recognition threshold test in the quiet environment and MHINT test respectively. We can learn the effect of wearing BAHA by doing the unaided and aided speech recognition threshold test in different environment.
BAHA had good compensation of aided threshold but have no obvious im prove of speech recognition threshold both in quiet and noise environment.
According to the research and feedback of patients, BAHA have no obvious benefit to unilateral profound hearing loss. The related benefit test should he done first before deciding whether or not to implant BAHA. The long-term BAHA wearing benefit still need to further understand with unilateral profound sensorineural hearing loss patients.
了解单侧极重度感音神经性听力损失患者佩戴骨传导助听器（BAHA）的益处。
16名单侧极重度感音神经性听力损失患者分别进行了BAHA助听后的纯音测试、安静环境下的言语识别阈测试以及MHINT测试。通过在不同环境下进行未佩戴和佩戴BAHA时的言语识别阈测试，我们可以了解佩戴BAHA的效果。
BAHA对助听阈值有良好的补偿作用，但在安静和噪声环境下，言语识别阈均无明显改善。
根据研究及患者反馈，BAHA对单侧极重度听力损失无明显益处。在决定是否植入BAHA之前，应先进行相关益处测试。对于单侧极重度感音神经性听力损失患者，BAHA佩戴的长期益处仍需进一步了解。
