摘要:

目的:了解翼钩凿断和板间切开对中耳功能的影响。方法:对20只新西兰大耳白兔行翼钩凿断和板间切开后,观察腭腱膜及中耳腔粘膜的变化,以明确手术对中耳功能的影响。结果:翼钩组均出现腭帆张肌松弛,中耳腔粘膜杯状细胞明显增多;板间切开组无1例出现上述变化。结论:翼钩凿断不利于咽鼓管的开张,而板间切开影响较小,因而主张腭裂手术时应尽量不凿断翼钩以保持其解剖位置和功能。

Abstract:

Objective:The aim of this study is to explore the effectof hamulotome on the eustachian tube function and verify the function of the tensor veli palatili muscle on eustachian tube.Methods:Single-sided hamulotome were carried out in the rabbits under the direct visual. And the middle ear cavity mucosa of the rabbitswas collected atdifferentintervals and dyedwith PAS and PHto ob- serve the middle ear changes under microscope.Results:Middle ear function changed obviously after the hamulotome, with in- crease in globular cells, submucosal edema and inflammatory cells. And mucin was not found in several cavities.Conclusion: Hamulotome do affecton the middle earfunction and should notbe damaged in orderto protectthe middle earfunction in some pa- tients.
