I saw this Cartilage palisade tympanoplasty and diving. - PubMed - NCBI which seemed positive. Now, I don't know if there are different methods other than what is described in this article. I'm going to schedule an appointment at Mass Eye and Ear to see what the Dr. says. Previously, he said they could do it but we decided to wait to see if I blew it again, that was 4 yrs ago.
