I can't be a fount of wisdom here because I only deal these days with CSOM and Eustachian tubes as part of the problem in my cleft-palate patients.
What I can say is that middle ear ventilation and eustachian tube dysfunction still isn't too well understood (that doesn't mean, BTW, that it isn't understood at all). Certainly cleft palate patients, where the tensor and levator palati are malinserted have faulty tubal opening and CSOM.
Quite why some folk who seem to be anatomically normal have tubal dysfunction is unclear. Perhaps the muscles just don't "work right". Incidentally, lysing muscle adhesions manually by "Trigeminal Pharyngioplasty" (which sounds like an operation but isn't) sounds odd to me - you don't usually see muscle "adhesions" and when you do, they need more than massage to take down. But if his patients are happy.......
I've no experience of laser surgery here - lots of people have these problems and if laser surgery is effective you can be sure that it will be in mainstream practice. Ask someone with an interest in tubal dysfunction whether it works or is just snake-oil.
I'm old enough to remember Politzerisation, so here are a few references.

Just remember, for every ill in this world there's a little man with a pendulum or a potion who's the only one who really really understands it......................................
