Infective ankylosis of incudostapedial joint 感染性砧镫关节强硬
When the threshold value was raised, the stapes, and the long crus of the incus, and the incudostapedial joint was diminished, and thin, and even disappeared. 随着观察阈值上限的升高,镫骨和/或砧骨长脚及其砧镫关节首先逐渐变小、变细乃至消失。
Conclusions There was a sound transmission loss within the incudostapedial joint, which was a physiological and protection way. 结论中耳传声过程中,在砧镫关节上存在着声损失,这种损失是生理性和保护性的。
A sound transmission loss within the incudostapedial joint was detected by electromechanical stimulation in 10 temporal bone models. 在等同于80dB声刺激的机械刺激条件下,测量10个颞骨标本砧镫关节的声损失。
The arterial supply of incudostapedial joint and the distal portion of the incuscomes from the vessels passing to them from the stapes rather than from the incudalsource. 关于砧镫关节及砧骨长脚下部的血供,来自镫骨方面的动脉多于砧骨方面的动脉。
The rates of visualization of the processus lenticularis, the stapes superstructure and the incudostapedial joint were 90%, 93.3%, 96.6%. 对豆状突、砧镫关节、镫骨上结构显示率分别为90%、93.3%、96.6%。
Results The average transmission loss within the incudostapedial joint remained 3 dB over the frequencies detected. 结果在所测量的频率中,砧镫关节上的声损失在3dB以内。
