[The evaluation of eustachian tube function in patients suffered from SOM with C type curve].
OBJECTIVE
To explore eustachian tube (ET) function in patients suffered from SOM with C type curve.


METHODS
To test the tympanogram following toynbee test and valsalva manoeuvre respectively. The shift of peak point was quantified and the results were compared with normal subjects.


RESULTS
ET dysfunction was found in 52.38% of the patients, it was observed in 30% of the normal subjects (P < 0.05).


CONCLUSIONS
ET dysfunction is one of the causes of SOM with C type curve, but not the only cause.
