概括
触觉辅助器,虽然在很大程度上已经过时了,但可能会在罕见的严重聋病例中受益. 作为触觉辅助器使用的骨传导装置 (BCD) 允许双侧耳无形成症患者将大声声音视为振动.
科学领域:
- 听力学 听力学是指听力学.
- 生物医学工程 生物医学工程
- 康复医学 康复医学 康复医学
背景情况:
- 耳植入物已经在很大程度上取代了对于严重聋的触觉辅助器.
- 触觉辅助可能仍然适用于特定的,罕见的病例.
- 博斯利-萨利赫-阿洛拉尼综合征表现为双边耳无形成症,这种情况使植入物不可行.
研究的目的:
- 评估骨传导装置 (BCD) 作为触觉辅助器的潜在实用性.
- 在患有双侧耳无形成症的患者中使用BCD评估声音感知值.
- 为了比较BCD在不同位置的表现 (后耳和手腕).
主要方法:
- 一名25岁的女性患有博斯利-萨利赫-阿洛拉尼综合征和双侧耳无形成症,被安装在软带上的BCD.
- 声检测值是用BCD测量后耳和手腕位置的.
- 三名成年耳植入物使用者进行了比较测试.
主要成果:
- 当BCD放在手腕上时,它可以以250-1000Hz (45-60dB) 的振动来感知声音.
- 后耳垂体放置产生了大约10dB较差的值.
- 声音分辨是个挑战,但病人可以感知大声的声音.
结论:
- 骨传导装置 (BCD) 在罕见的情况下可以作为触觉辅助器,在这种情况下,植入物不是一种选择.
- BCD的手腕位置可以促进触觉声音感知.
- 作为触觉辅助器的BCD的实用性仅限于低频率和大声的声音水平.

The Cochlea
45.3K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

The Auditory Ossicles
1.7K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Hearing
52.5K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Auditory Pathway
5.5K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Hair Cells
40.8K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
