概括
耳植入器接受者保持低频听力可能会从电声刺激 (EAS) 中受益,即使仅在电气使用后. 患者在使用EAS时表现出更好的文字识别,他们更喜欢它而不是仅用电刺激.
科学领域:
- 听力学 听力学是指听力学.
- 神经外科 神经外科
- 生物医学工程 生物医学工程
背景情况:
- 耳植入 (CI) 旨在恢复严重到严重的感觉神经听力损失的听力.
- 在CI后保持低频听力允许潜在的电声刺激 (EAS).
- 在先前仅用电刺激的患者中,EAS的益处尚未完全理解.
研究的目的:
- 为了评估EAS在CI接受者的有效性,残留低频听力,仅用电刺激一段时间后.
- 为了比较纯电,频率重叠的EAS (EAS-A) 和没有重叠的EAS (EAS-B) 编程之间的语音感知和主观结果.
主要方法:
- 一项前性交叉临床研究在私人诊所中进行.
- 剩余低频听力参与者接受了顺序编程:仅电,EAS-A和EAS-B.
- 语音感知 (CNC,AzBio) 和主观测量 (CCIQ,APHAB) 对于每个条件都进行了评估.
主要成果:
- 12名参与者完成了这项研究,分析了16个植入耳朵.
- 与纯电动 (65.5%) 和EAS-B (68%) (p <0.05) 相比,EAS-A (71.6%) 观察到CNC文字识别显著更好.
- 据报道,对EAS策略的显著偏好超过纯电刺激 (p = 0.04).
结论:
- 对于具有低频听力保护的CI用户来说,EAS可能比纯电刺激具有优势.
- 这种好处甚至在最初的纯电刺激期之后也持续存在.
- 进一步的研究是有必要的,以优化EAS编程这个患者群体.

01:31Hearing
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.
01:22Hair Cells
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.
01:13The Cochlea
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.
01:16Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
01:15Auditory Pathway
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.

01:17Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
