概括
在骨CT上的耳硬化病变在5-14年内长期显示出最小的尺寸和密度变化. 在这项研究中,没有观察到从窗性耳硬化症进展到后窗性耳硬化症.
科学领域:
- 放射学 放射学是一门学科.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 医疗成像医学成像
背景情况:
- 耳硬化是一种影响中耳的骨疾病,可能导致听力损失.
- 长期CT成像可以揭示疾病的进展,但随着时间的推移关于病变变化的数据有限.
研究的目的:
- 在骨CT扫描上评估耳硬化病变的长期进展.
- 为了评估病变扩张,分布和密度在5年至14年的变化.
主要方法:
- 在2012-2022年间,对35名患有耳硬化症的患者进行HRCT或CBCT后期分析.
- 纳入标准要求至少在五年内进行后续成像.
- 耳硬化亚型 (窗口,后窗口,IAC) 分析了病变密度和体积的变化.
主要成果:
- 在5至14年内,不到三分之一的患者表现出耳硬化体积增加 (16%的窗,20.6%的后窗).
- 窗外病例的密度增加了24%,窗外病例的密度增加了38.2%;在IAC病变中没有变化.
- 没有任何病例表明从窗口耳硬化进展到后窗口耳硬化.
结论:
- 耳硬化病变在5-14年内在尺寸和密度方面表现出最小的长期进展.
- 观察到的轻微形态变化与有限的听力损失进展相关.
- CT成像对于监测耳硬化有价值,在大多数患者中显示疾病进展缓慢.

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.
01:11The 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...
