Nasal polyp surgery is performed using endoscopic nasal polypectomy and sinusotomy. It is a minimally invasive surgery that requires general anesthesia and is painless. The cause of nasal polyps is unclear, generally, they are due to repeated chronic inflammation, which can cause diffuse congestion, edema, hyperplasia, and prolapse of the nasal turbinate mucosa. They are also often secondary to allergic rhinitis. Nasal polyps usually occur bilaterally and cause persistent nasal congestion that progressively worsens. During an endoscopic examination, pale, lychee-like fresh tumors can be seen in the nasal cavity, which are soft and painless. In terms of treatment, medication is ineffective for nasal polyps; patients need to undergo local surgical treatment for cure.
