骨锚定助听器（BAHA）是一种可植入的骨传导装置，通过手术植入耳后的钛螺钉直接振动颅骨。对于不能佩戴空气传导助听器的耳闭锁或慢性耳漏患者，BAHA具有优势。我们通过对2例慢性耳部问题患者在安静和嘈杂环境下的功能增益和言语辨别测试，比较了BAHA与传统骨和空气传导助听器的功能。与传统的骨传导助听器相比，所有人都明确表示更喜欢BAHA助听器。当每种助听器的功能增益一致时，BAHA助听器和空气传导助听器提供相似的听力学性能。然而，随着气骨间隙的扩大，使用BAHA的听力学性能表现出明显的偏好，这表明与空气传导助听器相比，气骨间隙的宽度对BAHA的偏好有一定的帮助。
The bone-anchored hearing aid (BAHA) is an implantable bone-conduction device that vibrates the skull directly via a surgically implanted titanium screw behind the ear. The BAHA has advantages for patients with aural atresia or chronic ear drainage, who cannot wear air-conduction hearing aids. We compared the function of BAHA to conventional bone and air-conduction hearing aids based on functional gain and speech discrimination tests in quiet and noisy environments in 2 patients with chronic ear problems. All expressed a clear preference for the BAHA over conventional bone-conduction hearing aids. The BAHA and air-conduction hearing aid provided similar audiological performance when the functional gain of each hearing aid coincided. As the air-bone gap widens, however, audiological performance with the BAHA showed an evident preference, indicating that the width of the air-bone gap is of some help in BAHA preference compared to air-conduction hearing aids.
