作者在诊治恶性外耳道炎的患者中发现二例在发病前均有水耳道冲洗的病史,为了明确这种冲洗在恶性外耳道炎发病机理中的作用,作了对照性研究。恶性外耳道炎共13例,女性4例,男性9例,年龄48～92岁,平均73岁。有11例不同程度地葡萄糖不耐性,其中7例依赖胰岛素,2例口服降糖药,2例葡萄糖耐受试验异常。设立的对照组共26例,其中女性8例,男性18例,平均年龄69岁(44～93岁),依赖胰岛素13例,口服降糖药12例,1例通过控制饮食稳定糖尿病。患者组中在发病前二周内有8例(61.5%)有耳道冲洗的病史,对照组中仅4例(15.4%)有此病史,统计学分析有意义(P<0.05),其它方面,诸如游泳、淋浴等二组比较无明显差异。
In the diagnosis and treatment of malignant otitis externa in patients with two cases were found before the onset of water ear canal irrigation history, in order to clarify the role of this flush in the pathogenesis of malignant otitis media, made a controlled study. Malignant external auditory canal inflammation in 13 cases, 4 females, 9 males, aged 48 to 92 years, mean 73 years. There were 11 cases of glucose intolerance to varying degrees, of which 7 cases of insulin dependent, 2 cases of oral hypoglycemic agents, 2 cases of glucose tolerance test abnormalities. The control group was established in 26 cases, including 8 females and 18 males. The mean age was 69 years old (44-93 years old). 13 cases were dependent on insulin, 12 cases were oral hypoglycemic agents and 1 case was stabilized diabetes by diet control. In the patient group, there were 8 cases (61.5%) having a history of ear canal irrigation in the first two weeks before onset, and only 4 cases (15.4%) in the control group had this history, and statistical analysis was significant (P <0.05) , Such as swimming, showering and other two groups no significant difference.
