    Abstract:
    OBJECTIVE: To investigate the association between the shape alteration of pharyngeal ostium of eustachian tube and secretory otitis media (SOM). METHOD: Two hundred and twelve pharyngeal ostiums of eustachian tube were observed by using rhinopharyngoscope and divided into two groups: the contrast's and the secretory otitis media's, and all the shape of pharyngeal ostium of eustachian tube were divided into triangular type, cravice type, elliptical type and bell type. RESULT: The shape of pharyngeal ostium of eustachian tube are remarkablely difference with the normal group and the diseased group. There are 84 cases triangular type (73%), 4 cases cravice type (3.5%), 17 cases bell type (8.7%) and 10 cases elliptical type (14.8%) in the former. There are 13 cases triangular type (13.4%), 68 cases cravice type (3.5%), 5 cases elliptical type (5.2%) and 11 cases bell type (11.3%) in the SOM group. CONCLUSION: The study suggest that there is a close association between the shape alteration of pharyngeal ostium of eustachian tube and secretory otitis media, meanwhile it offer a new index for exploring the new methods to cure the adult secretory otitis media how to resume the normal shape and the function of pharyngeal ostium of eustachian tube as soon as possible early.
