概括

侧半圆通道 (LSCC) 形,一个常见的内耳形,可以损害前庭功能. 在LSCC发育不良症中缺少中央骨岛 (CBI) 与降低前庭眼反射 (VOR) 功能有关.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
神经科学是一个神经科学.
医疗成像医学成像

背景情况:

侧半圆通道 (LSCC) 形是最常见的内耳形.
LSCC发育不良的频谱从轻微缩短到完全缺失中央骨岛 (CBI).
在LSCC发育不良和前庭功能缺陷之间的关系仍未得到充分研究.

研究的目的:

调查LSCC发育不良和前庭功能之间的关联.
为了比较患有和没有中央骨岛 (CBI) 的患者的前庭功能,在存在LSCC发育不良的情况下.

主要方法:

对17名患有LSCC发育不良的患者 (23个耳朵) 的回顾性分析.
使用热量测试和视频头脉冲测试 (vHIT) 评估前庭功能.
带有和没有中央骨岛 (CBI) 的耳朵之间的前庭功能参数的比较.

主要成果:

在69%的患者中发现了热量测试中的异常,而92%的患者在vHIT上显示了正常的LSCC前庭眼反射 (VOR) 增加.
在热量测试慢相速度和LSCC VOR增益 (r=0.792,p=0.004) 之间观察到显著的相关性.
没有中央骨岛 (CBI) 的耳朵与CBI (分别p=0.001和p=0.004) 的耳朵相比,表现出明显较低的慢相速度和LSCC VOR增长.

结论:

这种LSCC发育不良会对前庭眼镜反射 (VOR) 功能产生负面影响.
在LSCC发育不良症中缺少中央骨岛 (CBI) 与更显著的前庭功能障碍有关.

Equilibrium and Balance

Equilibrium and Balance

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...

Anatomy of the Ear

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...
