In section specimens of 20 infants aged 2 months to one year the morphology of the middle ear was studied in comparison with 20 adult cases aged 20-50 years. The differences were in size and shape of the tympanic cavity, eustachian tube, mastoid and middle ear ossicles. The comparison of dimensions of auditory ossicles in the infants and in adults shows that the length of malleus increases 11.9%, the length of manubrium mallei--11.5%, crus longum incudis--10.2%, the incus length--7.6%, incus width--8.2%, stapes length--4.5%, length of stapes basis--5.3%, width of stapes basis--7.5%. These data may be useful in pediatric otolaryngology.
在20例年龄为2个月至1岁婴儿的颞骨标本中，对中耳形态进行了研究，并与20例年龄在20 - 50岁的成人病例作比较。差异存在于鼓室、咽鼓管、乳突及中耳听小骨的大小和形状。婴儿与成人听小骨尺寸的比较显示，锤骨长度增加11.9%，锤骨柄长度增加11.5%，砧骨长脚长度增加10.2%，砧骨长度增加7.6%，砧骨宽度增加8.2%，镫骨长度增加4.5%，镫骨底长度增加5.3%，镫骨底宽度增加7.5%。这些数据可能在小儿耳鼻咽喉科中有用。
