概括

这项研究分析了112名患者的时间CT扫描,以测量圆窗 (RW) 和周围结构,这对于耳植入物 (CI) 手术至关重要. 结果显示了解剖学变异,雄性具有更大的RW直径和更好的乳腺气动化.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
放射学放射学是一门学科.
人体解剖学解剖学解剖学

背景情况:

圆形窗口 (RW) 是耳植入物 (CI) 电极插入的关键地标.
了解RW和相邻结构的解剖学变异对于成功的CI手术至关重要.

研究的目的:

通过使用时间计算机断层扫描 (CT) 来调查圆窗 (RW) 和邻近的解剖结构的尺寸.
分析RW尺寸,乳头气动化和距离到关键结构,如管 (CC) 和球 (JB) 之间的关系.

主要方法:

从112名成年患者的时间CT图像进行了回顾性分析.
状体气动化的分类和RW直径的测量,RW-CC距离,RW-面部神经状体段 (FNMS) 距离,RW-金字塔突出距离,RW-状球 (JB) 距离,RW-内部声道 (IAC) 距离.
测量RW-cochlea角度和RW-面部神经角度.

主要成果:

与女性相比,男性的RW直径显著更大 (p <0.05).
男人表现出更好的乳腺肺炎 (p < 0.05).
RW-CC和RW-JB的距离始终小于10毫米,RW-JB距离随着RW直径的增加而减少,而在气动化形动物中则增加. RW-JB和RW-CC的距离显示出正相关性 (p < 0.05).

The Cochlea

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.

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...
