We studied 186 ears in 109 children aged 0-12 years with otitis media with effusion (OME) and recurrent acute otitis media who underwent the insertion of a short-term ventilation tube (Shepard Grommet tube) at Tomakomai ENT clinic between 2008 and 2011. The average age at the time of insertion was 3.3 years, and general anesthesia was required for 2 out of 302 ventilation tube insertions. The tubes were removed after an average of 227 days. Sequelae from indwelling tubes included otorrhea (18.2%), and obstruction (12.9%). No perforation, adhesion and cholesteatoma was occurred after tube extraction. In children aged 2 or over, the recurrence rate of OME requiring a second ventilation tube insertion was significantly higher in the group without chronic sinusitis during intubation than in the group with chronic sinusitis. The cure rate for otitis media was significantly higher in the group intubated for 5 months or longer, compared with the group intubated for less than 5 months.
