Postoperative care measures for nasal polyps are as follows: 1. Adopt a semi-recumbent position after surgery to facilitate the drainage of nasal and sinus secretions and reduce nasal congestion; 2. Eat more high-protein, high-calorie, vitamin-rich and easy-to-digest foods to increase the patient’s resistance; 3. Strengthen nasal irrigation after surgery to clear nasal secretions in a timely manner and prevent the occurrence of adhesions; 4. Instruct patients to follow up on time to remove the hyperplastic vesicles and residual lesion tissues to improve the effect of surgery.
