It is advised to use the Valsalva movement to relieve negative middle ear pressure. We provide two techniques to increase the effectiveness of auto-inflation processes. 134 passengers were the study's participants, and they were assessed following the trip.
Methods: After a flight, travellers might take advantage of an ear checkup that
included tympanometry and otoscopy. The passengers were instructed to do a
Valsalva manoeuvre and then tympanometry was repeated if the middle ear
pressure readings following the trip were negative. An prolonged Valsalva
manoeuvre was done if the results were still negative. Tympanometry was then
performed once again if the auto-inflation procedure utilising a nasal balloon
was still unsuccessful.
Results: After performing the Valsalva technique, 19 ears (14 percent) of the
134 ears with initially negative middle ear pressures had their middle ear
pressure return to normal. 53 ears among the 115 passengers who still had
negative pressure experienced equalisation to zero or positive pressure (46
percent ). 43 participants (69 percent) were able to normalise the middle ear
pressure in the 62 ears that still had a negative middle ear pressure following
the Valsalva and prolonged Valsalva manoeuvres. After all the autoinflation
operations, 19 individuals out of 134 still had a negative pressure.
