对1 408例取自尸检的颞骨进行病理学研究。对其中发现中耳或/和乳突有渗液或慢性病变的229例颞骨就以下问题作进一步的检查,以确定:①渗液的性质(浆液性、脓性或粘液性);②上皮的类型;③慢性病理组织的类型及程度(肉芽组织、胆固醇肉芽肿、胆脂瘤),④鼓窦入口是否堵塞及堵塞的性质;⑤是否面神经有炎性细胞浸润;⑥是否鼓膜有穿孔或内陷。229例颞骨中,渗液或病变局限在中耳的有9例,局限在乳突的有7例,中耳和乳突均有渗液或/和病变组织的213例。中耳内常见的柱状和杯状细胞在229例乳突腔内均未能见
Pathological studies were performed on 1 408 temporal bone taken from an autopsy. Of the 229 temporal bone found to have exudate or chronic lesions of the middle ear and / or mastoid, the following questions were further examined to determine: (1) the nature of the effusion (serous, purulent or mucinous); Type; ③ the type and degree of chronic pathological tissue (granulation tissue, granuloma, cholesterol gallstone, cholesteatoma), ④ the entrance to the drum sinus is blocked and the nature of the block; ⑤ whether the facial nerve inflammatory cell infiltration; ⑥ whether the tympanic membrane perforation or within trap. In 229 cases of temporal bone, there were 9 cases of exudate or lesion confined to the middle ear, 7 cases were confined to mastoid, 213 cases of exudation and / or lesion in the middle ear and mastoid. The common columnar and goblet cells in the middle ear were not seen in 229 cases of mastoid cavity
