I have had Eustachian tube dysfunction since I was a teenager (now 64) and have had hearing issues the whole time - despite hearing tests always being normal until now. I would be cautious about any procedure without evidence that it’s required. I would also advise you to do your research about the longevity of the results as I have heard that the benefit of the results only lasts a few years, but I don’t know if this is correct.
I asked my GP (UK) to refer me to ENT back in 2019, but he refused saying “there’s no point as there’s nothing they can do about it” my reply was “so I have to carry on with my husband calling me a deaf old bat” (NB this is fun banter which is part of us) and he laughed and said yes.
I would very much like to know from any professionals on here what an audiogram would look like in the case of Eustachian tube dysfunction as I have wondered how much of my hearing loss can be explained by it. I did put this question on the ask a professional section quite a while ago, but have not had an answer.
