Was wondering if anyone has ever had a horse with this condition and if you have had surgery to correct it? My 16 year old Morgan gelding was diagnosed about a year ago. The vet also calls it roaring, the left vocal fold (cord) is paralyzed, they will go in and tieback the fold so it stays permanently open. As of right now I can't ride him, he is to have to no forced exercise as he has a hard time breathing when exercised. I am debating on having the surgery done as it is expensive, am wondering if anyone that has had this surgery has had good luck with it???
