Treatment of severe otitis media with effusion with adenoidectomy and myringotomy:with a report of 36 cases

Objective: To detect the treatment effects of severe otitis media with effusion with adenoidectomy and myringotomy.Methods: 36 cases of severe otitis media with effusion , which had been treated with conservative methods for long time , were studied. All patients had got otoscope , nasal pharynx X-ray screen, nasoendoscope ,hearing and tympanogram examination and were followed up 6 months to 3 years after operation. Results: 26 cases′ hearings recovered within 6 months while their tympanograms showed that tympano- pressures ranged from 40-80mmH 20. Other 6 cases′ hearing also restored except one or tow frequencies of audiograms decreased 10-20 dB. 4 casas still had slightly conductive hearing loss. Nasal pharynx X-ray films of all cases showed that the track of nasal pharynx were wide and the enlarged adenoids disappeared. Naso-pharynxscope exams indicated that the openings of eustachian tubes were normal.Conclusion: The mainly reason of otitis media with effusion is oppressed by the enlarged adenoids, and nasal pharynxscope exams is the effective way to find it. Hearing level can restored rapidly.After the myringotomy, adenoidectomy can avoid the recurrence of otitis media with effusion.
