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.
