外耳道炎最常见的致病菌是:绿脓杆菌、大肠杆菌、变形杆菌及葡萄球菌等,混合感染也常见。对一般外耳道炎最好是局部清洁及联合使用抗生素和泼尼松制剂。但在热带气候下患外耳道炎时,有80％为霉菌感染(念珠菌、曲霉菌等)。有些病例在持续使用抗生素后,反而有利于外耳道内霉菌生长。作者们用clobetasol丙酸盐制剂,对32例双侧外耳道炎和17例单侧外耳道炎进行观察。制剂的成份是:抗炎性类固醇——(clobatasol丙酸盐0.05％)以及抗生素——(四环素3.0％)、抗霉菌制剂——(制霉菌素110,000单位/ml)。同时与otosporin(新霉素、多粘菌素、氢化可的松)比
The most common pathogen of otitis externa is Pseudomonas aeruginosa, Escherichia coli, Proteus and Staphylococcus aureus, and mixed infections are also common. For general otitis externa, it is best to topically clean and combine antibiotics and prednisone preparations. However, when suffering from otitis externa in tropical climates, 80% are mold infections (Candida, Aspergillus, etc.). In some cases continued use of antibiotics, but conducive to mold growth in the external auditory canal. The authors used clobetasol propionate preparations to observe 32 cases of bilateral otitis externa and 17 cases of unilateral otitis. The ingredients of the formulation are: anti-inflammatory steroid- (clobatasol propionate 0.05%) and antibiotic- (tetracycline 3.0%), antimycotic formulation- (nystatin 110,000 units / ml). At the same time with otosporin (neomycin, polymyxin, hydrocortisone) ratio
