Equilibrium and Balance01:15

Equilibrium and Balance

4.7K
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 System01:29

The Vestibular System

39.5K
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.

此摘要是机器生成的。

头部受伤后的中枢前庭功能障碍 (CVD) 是罕见的,通常与严重的创伤和扩散的轴突损伤有关. 失衡是比起头更常见的症状,眼睛运动异常表明中枢神经系统受伤.

科学领域:

  • 神经科学是一个神经科学.
  • 耳鼻喉科 耳鼻喉科 耳鼻喉科
  • 创伤学 创伤学 创伤学

背景情况:

  • 头是头部受伤的常见后果.
  • 区分中央前庭功能障碍 (CVD) 和外围原因对于适当的管理至关重要.
  • 以前的研究更多地关注的是外伤后的外围前庭损伤.

研究的目的:

  • 在头部受伤的个体中描述中央前庭功能障碍 (CVD) 的特征.
  • 为了比较心血管疾病的临床表现与外周前庭功能障碍创伤后.
  • 为了识别创伤后头中中枢神经系统损伤的潜在指标.

主要方法:

  • 大学健康网络 (UHN) 工作场所安全和保险委员会 (WSIB) 神经病学数据库 (1998-2018) 的回顾性研究.
  • 包括头部受伤的工人,呈现出暗示心血管疾病的特征.
  • 综合的神经病学评估,包括病史,检查,听觉静脉检测 (VNG,cVEMPs) 和神经成像 (CT,MRI).

主要成果:

  • 在4291名头部受伤的工人中,23人被诊断患有心血管疾病.
  • 与和头痛相比,心血管疾病患者中失衡的发生率明显高于外围前庭功能障碍患者.
  • 在心血管疾病组中,不典型的位置性阴囊,眼运动异常和面部更为频繁.

结论:

  • 症状性创伤后中央前庭损伤是一种不常见的诊断.
  • 心血管疾病通常是在高冲击创伤之后发生的,这表明严重的头部损伤和潜在的扩散轴突损伤.
  • 持续的失衡和动力衰竭是心血管疾病比起更常见的症状.
  • 眼动异常是中枢神经系统损伤的强有力的指标,即使CT/MRI检测结果正常.
