作者对25例尸体的50块颞骨作了检查,女15例,男10例,在眶上缘上约1英寸处水平切开颅骨,取除脑组织,完整保留硬脑膜及颅底。环科检查以排除中耳疾病和胆脂瘤,骨检查无转移性瘤。颞骨解剖采用显微镜,对覆盖在盖板和岩乳部的硬脑膜作了检查,仔细地分离硬脑膜的两层,对它们可能存在缺损的大小、形状和数量十分注意。缺损通过细针探入乳突气房和中耳而得以证实。 The author examined 25 temporal bodies of 50 temporal bones, 15 females and 10 males. The skull was cut horizontally at about 1 inch above the supraorbital margin, and the brain tissues were removed to preserve the dura and skull base intact. Central examination to exclude middle ear disease and cholesteatoma, bone metastases without tumor. Temporal Bone Anatomy A microscope was used to examine the dura covered by the cover and the rock larynx. Care was taken to separate the two layers of the dura, paying particular attention to the size, shape and number of defects they may have. Defects were confirmed by fine needle probing into the mastoid atrium and middle ear.
