概括
耳植入物 (CI) 成功地恢复了三名阿尔波特综合征患者的听力,显示了语音感知和听力值的显著改善. 这些发现表明CI是阿尔波特综合征相关听力损失的可行选择.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 遗传学 是一个遗传学.
- 听力学 听力学是指听力学.
背景情况:
- 阿尔波特综合征是一种影响原蛋白的遗传性疾病,往往导致渐进的感觉神经听力损失.
- 阿尔波特综合征的听力损失可以显著影响生活质量和沟通.
研究的目的:
- 评估在被诊断患有阿尔波特综合征的家族患者中耳植入 (CI) 的临床结果.
- 评估CI在解决与阿尔波特综合征相关的渐进性神经感官听力损失方面的有效性.
主要方法:
- 一个涉及三个家族患者 (父亲和两个女儿) 的病例系列,他们患有阿尔波特综合征,接受了耳植入.
- 使用了手术前和手术后的听觉评估,包括纯音调平均 (PTA),辅音-核心-辅音 (CNC) 评分和亚利桑那生物工业协会 (AzBio) 评分.
主要成果:
- 患者在植入后的PTA,CNC和AzBio分数显著改善.
- 一位患者在CI后10年实现了92%的CNC和87%的AzBio得分,而另一位患者在CI后3个月显示了84%的CNC和62%的AzBio得分.
- 该研究强调了成功的单边CI结果,在这个患者队列中没有并发症.
结论:
- 单侧耳植入是一种安全有效的治疗阿尔波特综合征听力损失的方法.
- 对艾尔波特综合征和其他原相关疾病患者的CI疗效进行进一步的研究是有必要的.

Hearing
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.
The 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.
The Auditory Ossicles
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...

Anatomy 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...
