中耳传导装置成形外科的目的,在于修补由炎症或外伤而破坏了的中耳传导装置,徒而改善听力。这种术式经Zllner,WnllsTein及Moritz等诸氏之努力,在最近几年来才获得进展。音响传导装置包括:鼓膜、听小骨、耳内肌肉、卵圆窗及圆窗和外淋巴。声波进入外听道后经鼓膜以及三个听小骨的连锁传到卵圆窗。三个听小骨形成了将鼓膜振动传至卵圆窗的杠捍系统。锤骨及砧骨虽然彼此间以关 Middle Ear Conductive Shaping Surgery aims to repair middle ear conduction devices damaged by inflammation or trauma to improve hearing. This technique has not progressed in recent years with the efforts of Zhullies such as Zllner, WnllsTein and Moritz. Acoustic conduction devices include: tympanic membrane, ossicles, intramuscular muscles, oval and round windows and perilymph. Sound waves into the external auditory canal after the tympanic membrane and the three ossicular chain reached the oval window. The three ossicles form a bar-guard system that transmits the tympanic membrane vibrations to the oval window. Although the malleus and the incus to each other off
