Objective To study the clinical efficacy of the treatment in secretory otitis media （SOM） by ambroxol with the mode of retrograde eustachian tube and tympanic membrane puncture. Methods 179 cases were randomly divided into 3 groups. The 1st observation group was giuen the mode of retrograde eustachian tube for tympanic cavity irrigation with ambroxol， the 2st observation group was giuen the mode of tympanic membrane puncture for irrigation with ambroxol，and the control group was giuen the mode of tympanic membrane puncture for irrigation with dexamethasone. The changes of language frequency threshold of three groups were compared before and after treatment， and the complications after treatment were evaluated statistically. Results The language frequency hearing was improved after treatment in the three groups （ < 0.05） . The effect of the 1st and 2st observation groups were all higher than that of control group （ < 0.05）， but there was no difference between two observation groups （ > 0.05） . Conclusion Ambroxol is clinically effective to treat SOM，and retrograde eustachian tube insertion is safe and reliable， so the method is worth clinical application． [ABSTRACT FROM AUTHOR]
