Nasal polyps are benign tumors that occur inside the nasal cavity. Generally, the appearance of nasal polyps is associated with chronic inflammatory stimulation, repeated irritation of the turbinate mucosa leading to congestion, edema, prolapse, and hyperplasia of the turbinate mucosa, which causes nasal polyps. They are also often secondary to allergic rhinitis. Nasal polyps can cause bilateral nasal congestion in patients, which tends to persist and worsen, while mucous secretions may also flow from the nasal cavity. In severe cases, patients may experience facial swelling, pain, headaches, and other related symptoms. During examination, pale white lychee-like, soft new growths that are usually painless can be found inside the nasal cavity. In terms of treatment, nasal polyps require endoscopic nasal polypectomy. The surgery requires hospitalization, general anesthesia, and postoperative antibiotics to prevent local infection. Patients can usually recover and be discharged about a week after the surgery. (The use of medications should be under the guidance of a professional doctor.)
