Does Successful Myringoplasty Affect Eustachian Tube Function?

Introduction  Eustachian tube is a tube connecting the middle ear cavity with the nasopharynx and has a very important role in equalization of pressure around TM.

Many studies investigate the role of ET function tests on the results of Myringoplasty/tympanoplasty. Our aim of the study is to assess the effect of successful Myringoplasty on the Eustachian tube function.

Methods  A prospective study included 37 patients who were admitted to the E.N.T Department at Sohag University Hospital during the period between March 2018 to March 2019 suffering from dry central perforation necessitating myringoplasty. Pre-operative E.T function tests using tympanometry and methylene blue dye test. Post-operative follow-up tympanometry after 3 months was recorded for successful Myringoplasty patients.

Results  (83%) of patients were functioning ET and (17%) were non-functioning ET with a success rate of 86.5% (taken graft cases). According to the effect of Myringoplasty on ET function test after operation by 3 months, (9%) were affected either improved (3%) or worsen (6%), while (91%) did not affect by tympanometry to taken graft cases.

Conclusion  E.T has a very important role in the health of the middle ear. There are many E.T function tests; one of these is tympanometry and passage of methylene blue dye. In our study, there was no effect of Myringoplasty on E.T function.
