Sixty ears of 33 children with otitis media with effusion (OME), which had not been improved by conservative treatment, had adenotomy and ventilation tube insertion (VT), were studied. Out of 33 cases, 17 had also tonsillectomy. But there was no significant difference of improvement of OME between cases with or without tonsillectomy. Inprovement of OME was found in cases of 70%.
The cases with VT for more than 3 months seemed to have better improvement rate.
There were many patients whose VT was removed from March to May showed poor result. It had been reported that many OME cases were suffering from chronic sinusitis or nasal allergy simultaneously. And, in general, these nasal synptoms were more likely aggravated in Spring.
As the result, it is concluded that the removal of ventilation tube from March to May was not appropriate for treatment of OME.
