[Mastoidectomy and ventilation tube placement for refractory secretory otitis media].

OBJECTIVE

To study the mastoidectomy and ventilation tube placement for refractory secretory otitis media of clinical efficacy and mechanism.

METHOD

Retrospective analysis of 22 patients (33 ears) in refractory secretory otitis media, all patients treated by ventilation tube placement have 3 or more than 3 times, but not significantly alleviate the symptoms. Mastoid surgery and ventilation tube placement were basic surgical management. Tympanic membrane ventilation tube was pulled out at 3 to 6 months.

RESULT

Twenty-two patients perceived improvement of hearing after surgery, ear fullness disappeared; tympanic membrane was gray, no significant tympanic membrane mobility is limited; 33 ears conductive hearing loss, air-bone gap(13.54 +/- 4.86) dB; after 29 ears tympanograms showed A-type, 4 ears for C-type, 30 ears appear ipsilateral acoustic reflex.

CONCLUSION

For 3 or more than 3 times repeated ventilation tube insertion, patients more than 2 years of refractory secretory otitis media were treated with mastoidectomy and ventilation tube placement, it was satisfied that ears lesions were cleaned and expanded middle ear and mastoid air cell volume, good drainage of the tympanic membrane ventilation tube.
