Abstract:
Objective To investigate and contrastive analyse the respective value of tympanograms and high resolution CT scan of temporal bone in the diagnosis of secretory otitis media .Methods The clinical data of 150 hos-pitalized patients with secretory otitis media in Department of ENTHNS ,Tongji Hospital ,Wuhan from 2009 to 2012 were retrospectively analyzed .Based on the surgical finding of tympanic cavity fluid ,the diagnostic accordance rate of tympanograms and temporal bone CT for middle ear effusion were calculated respectively ,and their diagnos-tic value were evaluated .Results The diagnostic accordance rate of tympanogram B for the middle ear effusion in secretory otitis media was 94 .5% (138/146 ears) ,the rate of abnormal tympanograms was 91 .6% (206/225 ears) , while temporal bone CT with a rate of 99 .2% (117/118 ears) .The difference between the latter two data was statis-tically significant(P<0 .01) .Conclusion The temporal bone CT scan ,with a higher diagnostic value for middle ear effusion in secretory otitis media ,could be used as a supplement to the acoustic immittance measurement ,especially to non-B tympanograms for the diagnosis of secretory otitis midia .
