My wife just had this surgery herself and it took about two months to be painfree. Her surgeon used a technique that did away with the nose plugs used previously to stop bleeding but extremely painful to remove.
He just didn't use the plugs. It worked but still took 2 months to recover and not pain free, although it had to have been less painful than extracting that plug.
This new work makes a gel out of ones own blood (no immune response) that uses some kind of cow hormone that when mixed with blood reacts with the nasal passage to make a gel that stops bleeding and doesn't need to be removed.
Anyone who has a sinus infection bad enough to require surgery should read this.
