软骨在鼓室成形术中的应用

Application of cartilage in tympanoplasty

自Heermann采用条栅状软骨技术修补鼓膜大穿孔后,软骨在耳外科手术中获得了快速的发展。因软骨具有取材方便、稳定性高、弹性好、代谢率低、易于存活和可塑性强等优点,已广泛应用于鼓膜成形术、听骨链重建术、上鼓室外侧壁及外耳道后壁的重建中。本文就软骨在鼓室成形术中的应用作一综述,并探讨在Ⅱ型鼓室成形术中将软骨置于镫骨头上行听骨链重建的可能性。

Cartilage has undergone rapid development in ear surgery since Heermann used the grid cartilage technique to repair large perforations of the tympanic membrane.Cartilage has been widely used in tympanoplasty,ossicular chain reconstruction,reconstruction of the lateral wall of the upper tympanic cavity and the posterior wall of the external auditory canal due to its advantages of convenient sampling,high stability,good elasticity,low metabolic rate,easy survival and strong plasticity.This paper reviews the use of cartilage in tympanoplasty and discusses the possibility of placing cartilage on the stapes head for reconstruction of the auditory chain in type Ⅱ tympanoplasty.
