Background and Objectives Pre-operative eustachian tube function (ETF) is an importantfactor for the postoperative success after tympanoplasty, though much debates have been reported.
In this study, we investigated the tympanogram changes after tympanoplasty, indirectlychecking up ETF, to find out the relationship between tympanogram changes and associatedfactors of tympanoplasty.
Subjects and Method Included in this study were 238 cases of tympanoplasty (canal wallup mastoidectomy with tympanoplasty type I or tympanoplasty type I only) performed by onesurgeon for chronic otitis media from January, 2012 to June, 2017. In all cases, tympanometrictests were undertaken at one month, three month, six month, and one year post-operatively,and pure tone audiometry tests were taken at 1 year, post operatively.
Results The average hearing level and air-bone gap were 41.8±19.7 dB, and 17.1±9.3 dB,pre-operatively, and 29.9±21.1 dB, and 6.9±8.5 dB, 1 year post-operatively, respectively. Mostof the cases showed improvement in hearing. The results of tympanometry showed that hearingimprovement was greater for the A type than for the B or C type (p＜0.001). The smaller thesize of the tympanic membrane was, the higher, the type A tympanogram appeared to be (p=0.008).
Conclusion The estimation of pre-operative ETF using post-operative tympanogram changescan give insight to the degree and process of recovery of the normal middle ear after tympanoplasty
