Results: The data of 120 patients were analyzed, and 60 patients were in the group of levofloxacin ear drop and the other 60 in the group of ofloxacin ear drop. Efficacy assessment based on symptom score reducing index showed that the efficacy rate of levofloxacin ear drop was 96.67% and that of the ofloxacin ear drop was 85.00%; the eradication rate of pathogens in the group of levofloxacin ear drop was 96.15% and in the group of ofloxacin ear drop was 95.83%. No significant difference was showed between two groups (both P＜0.05). Conclusions: Levofloxacin ear drop is effective and safe in treating otitis media.
