听小骨为人体内最小的一组骨,含锤骨、砧骨和镫骨,三者相连成骨链将声波由鼓膜经鼓室传至内耳。原态原位听小骨标本在解剖实验教学中十分紧缺,初学者不易正确建立听小骨空间结构模型,对听小骨的相关学习造成一定的影响,笔者在制作过程中摸索出由前下壁入路制作听小骨标本的方法,介绍如下:1材料与方法 Listen to the smallest bone in the human body a group of bone, including malleus, incus and tarsal bone, the three connected to the sonic chain from the tympanic membrane to the inner ear through the tympanic cavity. The original orthotopic ossicular specimens in the teaching of anatomy and experimental teaching is very scarce, it is not easy for beginners to correctly establish the ossicular spatial structure model, the learning of the ossicles caused some impact, the author found in the production process by the anterior and inferior wall approach The method of making a small bone specimens, introduced as follows: 1 Materials and methods
