Abstract

OBJECTIVE

To study the method on comprehensive evaluation of the middle ear function in children with secretory otitis media (SOM) after tympanotomy tube insertion.

METHOD

Ear canal volume (ECV), pure tone audiometry and distortion product otoacoustic emission(DPOAE) were carried out in 31 children(43 ears) with SOM before and 1 month after tube insertion,in the meantime Eustachian tube function was recorded. The tympanotomy tube was observed under microscope.

RESULT

After one month of tube insertion, the hearing level was improved in 39 ears with an ECV > 2.0 ml. In addition,the detection rate and amplitude of DPOAE were significantly increased in these 39 ears. No case of the function of Eustachian tube was complete recovered.

CONCLUSION

ECV, pure tone audiometry, DPOAE and inflation-deflation test are significantly clinical worth for comprehensive evaluation of the middle ear function in children with SOM after tympanotomy tube insertion.
