What causes buzzing sound in ear after tympanoplasty? I read this post and wondered, if cartilage was used in my tympanoplasty surgery, and that is what is causing my tinnitus, what can be done about it? My dr did say something about the graph being thicker in one spot. I also have worse hearing than before the surgery, which was in April. I m just really discouraged by the results and it actually depresses me.
