The general public is concerned about the procedure of nasal polyp surgery and whether there are any risks associated with nasal polyp surgery. At present, endoscopy is basically used to perform nasal polyp surgery, in which the nasal endoscope is placed inside the nasal cavity and can be operated under the monitoring of the screen. The procedure of nasal polyp surgery is as follows: 1. astringent nasal cavity: the nasal cavity is astringently widened by astringent to clarify the location of the nasal polyp and the adjacent structures of the nasal polyp; 2. after the removal of the nasal polyp, some of the sinus openings can be observed and the sinuses are enlarged to clear the polyps and pus inside the sinuses; 3. if the nasal polyp invades the adjacent organs, it can lead to some other symptoms, which clinically Further treatment is needed and hemostasis can be performed by partial hemostatic devices; 4. After surgery, patients with nasal polyps often need some clinical caulking of the nasal cavity, because the trauma of the nasal cavity cannot be sutured and there is a large amount of exposed bone surface in the nasal cavity, so some hemostatic materials, including compressive materials, can be chosen clinically to stop bleeding.
