The medial and lateral attics were examined in 150 specimens of temporal bones of adults using anatomical and histological methods. The medial attic varies in shape and size, depending upon the position of the auditory ossicles, the degree of prominence of the lateral semicircular canal and the direction in which the tympanic segment of the facial canal extends. The latero-medical diameter of this attic at the level of the body of the incus averages 1.7 mm., but is somewhat smaller at the level of the head of the malleus. The medial attic always communicates with the mesotympanum through an opening between the prominence of the tympanic part of the facial canal and the superstructures of the auditory ossicles. The lateral attic is always of smaller dimensions than the medial attic and its latero-medial diameter averages less than 1 mm. This attic very seldom communicates with the mesotympanum.
采用解剖学和组织学方法，对150例成人颞骨标本的中耳上隐窝的内侧和外侧进行了检查。内侧上隐窝的形状和大小各不相同，这取决于听小骨的位置、外侧半规管的突出程度以及面神经管鼓室段的延伸方向。砧骨体水平处该上隐窝的内外径平均为1.7毫米，但在锤骨头水平处略小。内侧上隐窝总是通过面神经管鼓室部隆起与听小骨上部结构之间的开口与中鼓室相通。外侧上隐窝的尺寸总是小于内侧上隐窝，其内外径平均小于1毫米。该上隐窝很少与中鼓室相通。
