Hello @cemsid. I am not an ENT surgeon, but do have experience as a veterinary surgeon. These questions are better suited to be directed to your surgeon or another ENT. I don't know what kind of tonsil surgery you had, but if infection was involved than often incisions are left open to allow for drainage of infectious material. An incision may be left open to allow for normal fluid (serum) drainage to avoid swelling in a closed pocket. Open incisions heal slowly by secondary intention healing where healthy granulation tissue fills the opening until the surface skin or mucous membrane can grow over. Can you present your questions to your surgeon or the nurse to alleviate your stress?
