Nasal polyps are space-occupying lesions that occur in the nasal cavity and sinus cavity. After the discovery of nasal polyps, they are usually removed surgically. Currently, the surgery for nasal polyps is performed under general anesthesia using functional endoscopic sinus surgery, which involves removing the nasal polyps and opening the sinus ostia. There is no significant pain during the surgery, as it is conducted under general anesthesia. After the surgery, the nasal cavity is packed with some hemostatic materials. There is discomfort when this nasal packing material is removed on the second day after the surgery, but this discomfort is only significant during the removal and subsides afterward. Therefore, there is some pain associated with nasal polyp surgery, but the pain is not very severe.
