The results of a comparative study of long-term and short-term ventilation tubes for treatment of otitis media with effusion (OME) in children were reported. Koken tube type B^®was applied as a long-term ventilation tube and the straight tube was applied as a short-term ventilation tube.
The Koken tube type B^®was inserted into 299 ears of 167 children and the straight tube was inserted into 139 ears of 100 children between 1984 and 1989. The average intubation period was 15.9 months in the long-term study and 3.9 months in the short-term study. The recurrence rate of OME after the extubation was 15% in long-term intubation and 52% in short-term intubation. Complications occurred such as otorrhea, granulation and tympanic membrane perforation in 29% of long-term and in 5% of short-term intubation. Despite the significantly higher rate of the complications in the long-term group, there was no difference of the complications occurring per month between the longterm group and the short-term group.
It was concluded that the long-term ventilation tube had an advantage of lower recurrence rate without repetitive insertion for the treatment of OME in children.
