After comprehensive nasal surgery, a tampon was stuffed in the nose, and the doctor took it out less than 16 hours after the operation. Now two days after the operation, my nose is blocked and I have difficulty breathing. Postoperative poor nasal ventilation may be mainly due to nasal mucosal edema leading to nasal airway stenosis, or postoperative nasal mucosal adhesion leading to poor nasal ventilation. It is suggested that you can go to the hospital for a nasal endoscope to have a detailed look, and let the doctor prescribe some nasal lotion to wash it at home to improve the situation.
