Conclusion hearing loss due to outer and middle ear malformation , the reconstruction not only rely on ossicle chain but ought to pay more attention on mobilization of stapes and oval window occlusion .
Different types of middle ear implants always have their actuators stimulated different positions of the ossicular chain . The effect of such stimulating placement on stapes movement is rarely investigated .
各款人工中耳中作动器的激振部位都有所不同,但这种激振位置的不同对镫骨运动的影响鲜有研究。
Conclusionsconnecting artificial ossicle to tympanic membrane at its central position is optimal for the dynamic response of ear structure as the amplitude of stapes footplate under this situation is slightly higher than other connecting methods since it conforms to physiological function of human ear , and the effect of hearing recovery could be better .
