Abstract

Objective To investigate the diagnostic value of endotoscopy,tympanometry,pure tone audiometry (PTA) and high resolution temporal bone CT in children with secretory otitis media (SOM).Methods The study comprised 414 ears in 207 children with adenoid hypertrophy.Endotoscopy,tympanometry,PTA and high resolution temporal bone CT were conducted to evaluate the function of middle ear.Based on the imaging findings of tympanic cavity fluid by high resolution temporal bone CT,the diagnostic accordance rate of endotoscopy,tympanograms and PTA for SOM were studied.Results The diagnostic accordance rate of endotoscopy,tympanometry and PTA for SOM were 98.79％(409/414),98.07％ (406/414) and 88.41％ (366/414),respectively.The sensitivity of the three examinations were 99.20％(124/125),100％ (125/125),63.20％ (79/125),respectively.The specificity of the three examinations were 98.62％ (285/289),97.23％ (281/289),99.31％ (287/289),respectively.The diagnostic accordance rate of endotoscopy combined with tympanometry for SOM was significantly higher than any single examination or any combined examinations.Conclusion Endotoscopy combined with tympanometry shows a great value in diagnosing SOM,which is accurate and safe.
