Hi, I’ve had the procedure twice in my left ear. I heard my heartbeat all day everyday in my ear and my muffled voice. Was driving me crazy because I also have bilateral tinnitus. I woke from first procedure and it was gone. It lasted about 3 months and it came back. I tried it again with tubes in the ear like kids get from many ear infections. It’s been 8 months and it’s good.
Your ENT can do certain tests right in the office that actually watch it open and close and tine testing around your head.
I also tries taping the eardrum but it didn’t work. My ENT tried that right in the office. The tube can be placed in the office. It might be something you want to discuss. Best of luck, it’s so annoying.
