We collected children with otitis media with effusion visiting our OPD during the past 2 years. There were 146 cases who had been followed up and treated for at least 3 months, including 79 boys and 67 girls with mean age of 4.8 years. Ventilation tube insertion were done in 64 cases who were failed the medical therapy after 3 months with bilateral hearing deficits of 20 dB or worse. Comparing the medical group and the surgical group, and observing the postoperative courses, we found that younger age was the meaningful risk factor of recurrent otitis media. Although no significant differences, male and association with other diseases such as chronic rhinitis, paranasal sinusitis, or adenoid hypertrophy were the possible risk factors. The postoperative otorrhea occurred in 31% patients. The ventilation tubes were extruded after mean period of 10.7 months.
