作者观察230例小儿渗出性中耳炎。只有一例在病程中发生中耳胆脂瘤,为7岁女孩。4岁时患急性中耳炎,行鼓膜切开术而治愈;6岁时确诊为渗出性中耳炎抽出粘胶液体,行鼓膜插管换气法,4个月后自然脱落,5个月后发现耳漏,并见外耳道后上壁生长出血性肉芽,2个月后该部形成骨疽,外耳道皮肤向上鼓室侵入,经一年保守治疗无效,始行中耳根治术并取出胆脂瘤。 Jordon等人提出:渗出性中耳炎可致中耳内粘连,继而鼓膜内外形成物理性张力,孤立的上鼓室形成负压,松弛膜内陷,最后形成边缘性穿孔而继发胆脂瘤;使用中耳换气管可沿鼓膜切口
The authors observed 230 cases of pediatric exudative otitis media. Only one case of middle ear cholesteatoma occurred in the course of the disease and was a 7-year-old girl. 4 years old suffering from acute otitis media, tympanotomy and cure; 6 years old was diagnosed as exudative otitis media drawn viscose fluid, tympanic membrane intubation ventilation method, natural shedding after 4 months, 5 months after the discovery of ear leaks , And see the external auditory canal after the growth of hemorrhagic granulation on the wall, 2 months after the Ministry of the formation of gangrene, external auditory meatus tympanic skin invasion, after one year of conservative treatment ineffective, the line of middle ear surgery and removal of cholesteatoma. Jordon et al proposed: exudative otitis media can cause adhesions in the middle ear, and then form a physical tension within the tympanic membrane, isolated on the tympanic cavity to form a negative pressure, relaxation of the membrane invagination, and finally the formation of marginal perforation and secondary to cholesteatoma; Middle ear trachea along the tympanic membrane incision
