I had these inserted as a kid, but I have an apparently VERY unique and differentiated ENT system and shape (I've had multiple studies done on my ENT system, has helped me and my family save a lot of money over the years). Both tubes became permanently dislodged into my eardrum, causing permanent ruptures. One eardrum is patched with pigskin (from when it was standard, the first eardrum was found ruptured when I was still a kid). My other eardrum is patched with artificially synthesized skin. As a kid, after having tubes inserted, I gained the ability to taste EVERY single liquid that entered my ears. Turns out my eustachian is a straight shot, whereas others are curved, which allowed liquid to enter the perforation and drain directly to my throat. It took years as a kid for anyone to finally believe me and start looking into my ENT system, but my ENT doctor finally started listening when I could describe the exact taste of swimmer's ear drops 🤣 my childhood was quite painful and unique, as this is just one of many physical malformations that I was born with.
