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 2 0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。Objective:The aim of this study is to explore the effect of 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 rabbits was collected at different intervals and dyed with PAS and PH to observe the middle ear changes under microscope. Results: Middle ear function changed obviously after the hamulotome, with increase in globular cells, submucosal edema and inflammatory cells. And mucin was not found in several cavities. Conclusion:Hamulotome do affect on the middle ear function and should not be damaged in order to protect the middle ear function in some patients.
