Submucosal resection of turbinates is a procedure to treat enlarged turbinates inside the nose. The turbinates are the parts of the nose that warm and humidify the air that you breathe in.
When the turbinates are enlarged, it causes nasal obstruction, making it hard to breathe. In the submucosal resection, the lining of the turbinate is left as it is, but the surgeon will take out some of the inside of the turbinate.
As it heals, the turbinate will be smaller than it was, making breathing easier. Some pain, swelling and drainage of mucous and blood are normal after the surgery, but should go away quickly.
