Objective:
To discussion the relationship of preoperative findings and ossicular condition in chronic suppurative otitis media.
Method:
The correlation between the ossicular conditions and classification of tympanic membrane perforation, ear discharge, air conduction pure tone average, air-bone gap, pneumatization, complication, and cholesteatoma in 251 patients(288 ears) with chronic suppurative otitis media was analysed.
Result:
The air-conduction threshold and air-bone gap in patients with ossicular discontinuity are higher than that in patients with ossicular continuity. Ossicular discontinuity in patients with perforation of the pars flaccida of tympanic membrane, persistently draining ears, complications, and cholesteatoma occurred significiantly more frequently than those without these conditions.
Conclusion:
The air-conduction threshold and air-bone gap are the more reliable indications to identify the ossicular conditions in patients with chronic suppurative otitis media. There are significiant correlation between the ossicular conditions in patients with chronic otitis media and their classification of tympanic membrane perforation, ear discharge, complication, and cholesteatoma.
