Objectives: To assess the efficacy of myringotomy for mild or severe acute otitis media cases conducted in our department and examine search backgrounds of these cases.
Methods: We studied 72 cases (117 ears) in which we carried out a myringotomy.
Results: The following results were obtained.
1. The frequency of detection of PISP in this study was greater than that in a 2007 National surveillance.
2. The treatment of mild acute otitis media cases with high dose AMPC, high dose CFPN-PI or AMPC/CVA (14:1) was effective. As a result, the cases of myringotomy in our department decreased from 44 cases in 2010 to 14 cases in 2011.
3. The efficacy rate 3 weeks after myringotomy was 91.7%, which is higher than that of other reports. On the other hand, the recurrence rate was 40.3%, which required treatments.
