概括
在有听力损失的儿童中,前庭水道扩大 (EVA) 是常见的. 这项研究没有发现EVA大小与听力损失严重程度或进展之间的相关性,但双边EVA与早期诊断和渐进性听力损失有关.
科学领域:
- 听力学 听力学是指听力学.
- 儿科耳鼻喉科 儿科耳鼻喉科
- 放射学 放射学是一门学科.
背景情况:
- 扩大前置水道 (EVA) 是儿科先天性神经神经听力损失 (SNHL) 中最常见的放射性发现.
- 辛辛那提标准 (部宽度≥2.0毫米和/或中点≥1.0毫米) 常用于EVA诊断.
- 了解EVA儿童的听力测量和听觉脑干响应 (ABR) 特性至关重要.
研究的目的:
- 为了检查一大批患有EVA和听力损失的儿科患者群体的听力测量和ABR特征.
- 扩大对与扩大前置水道相关的临床表现的理解.
- 调查EVA大小和听力损失模式之间的潜在相关性.
主要方法:
- 在2006年至2016年期间在第三级儿童医院诊断出EVA的儿童的回顾性图表审查.
- 对前置水道在部的测量进行分析.
- 对声度数据和听觉脑干响应 (ABR) 模式的评估.
主要成果:
- 包括106名儿童;60人有双边EVA.
- 双边EVA的儿童被诊断出听力损失明显比单边EVA的儿童年轻 (0.0vs5.0年).
- 最常见的ABR模式是SNHL类 (57%),大波I (28.6%) 和听力神经病变谱系障碍 (14.3%). 双边EVA与渐进性听力损失的可能性更高.

Anatomy of the Ear
7.1K
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...

Equilibrium and Balance
4.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System
39.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

The Cochlea
44.1K
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.

Auditory Pathway
4.5K
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.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

The Auditory Ossicles
1.5K
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...
