为获得慢性中耳炎的满意疗效和防治术后并发症,应首先了解引起该病的致病菌。作者们对1964～1971年因患慢性中耳炎行乳突根治术后的922耳进行研究。于术后5～14年每年定期复查,发现其中有感染的82例,女37,男45,年龄8～74岁,平均36.9岁。82例细菌学研究。溢脓61耳(粘液脓性18耳,浆液脓性34耳,粘液性分泌物9耳),潮湿24耳,共85耳。对湿耳和流脓耳进行比较,发现分泌物为粘脓性或稀脓性者多为绿脓杆菌、大肠杆菌、克雷白氏产气杆菌和假白喉菌属。湿耳细菌培养多为阴性、偶见变形菌属、葡萄球菌属。粘液性分泌物9耳中3耳单一感染(培养为一种细菌),一耳为双重感染(培养为两种细菌)。变形菌属、绿脓杆菌和葡萄球菌多见在术后感染无胆脂瘤耳中,克雷白氏产气杆菌经常发生
In order to obtain the satisfactory curative effect of chronic otitis media and to prevent postoperative complications, we should first understand the pathogenic bacteria that cause the disease. The authors studied 922 ears after radical mastectomy for chronic otitis media from 1964 to 1971. In 5 to 14 years after the regular annual review, found that 82 cases were infected, 37 women, 45 men, aged 8 to 74 years, mean 36.9 years. 82 cases of bacteriological studies. Pus 61 empyema (mucinous purulent 18 ears, 34 purulent serous pulp, mucus secretions 9 ears), wet 24 ears, a total of 85 ears. On the wet ear and streptococcal ear were compared and found secretions of purulent or purulent were mostly Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae and Pseudobunella genus. Wet ear bacteria culture mostly negative, occasionally Proteus, Staphylococcus. 3 mucosal secretions in 9 ears of a single infection (cultured as a bacteria), a double infection of the ears (culture of two kinds of bacteria). Proteus, Pseudomonas aeruginosa and staphylococcus more common in postoperative infection without cholesteatoma ear, Klebsiella pneumoniae often occurs
