摘要
目的观察兔听泡解剖结构,了解耳后进路手术标志。方法选择健康兔,制作颅骨标本,观察听泡大体形态及位置,取活体兔听泡,使用耳内镜及病理学方法观察其结构特点。选择耳后手术径路,观察活体兔此径路术中手术标志。结果兔听泡体积较大,听骨及内耳结构主要集中于听泡前方,取其耳后切口,沿骨性外耳道后壁,寻找茎突样结构,经听泡后壁可顺利进入听泡,不会损伤重要结构。结论耳后切口,经听泡后壁可进入兔听泡,不损伤重要结构,可应用于基于兔听泡的相关实验研究。
To observe the anatomy of the rabbit＇s bullae and the landmarks of the retroauricular surgical approach. METHODS Healthy rabbits were chosen to make skull bone specimen and shape and position of the bullae were the studied. The detailed structures of fresh bullae were observed through endoscope and pathological technique. Then the landmarks of the retroauricular approach in a real surgery were marked. RESULTS There was a large cavity in the bullae. The rabbit＇s ossicle and inner ear are in the anterior part of the bullae. From the retroauricular incision, following the posterior bone wall of the external auditory canal, we can find the styloid- like structure. Trough the posterior wall of the bullae, we can open the bullae without damage the important structures. CONCLUSION Through the retroauricular incision and surgical approach, we can enter the rabbit＇s bullae easily, and this technique can be used in the experiments based on rabbit＇s bullae.
