Minimally invasive surgery for nasal polyps usually refers to functional endoscopic sinus surgery. In patients with nasal polyps obstructing the nasal passages, the polyps are removed under visualization using a nasal endoscope. For patients with bilateral nasal polyps, the surgery generally lasts about one to one and a half hours. Patients with nasal polyps typically experience significant symptoms such as nasal congestion, runny nose, and headaches. These polyps block the sinus openings, affecting sinus drainage, thus surgery is usually necessary. After undergoing functional endoscopic sinus surgery, patients should avoid hot baths, foot baths, and vigorous exercise to prevent post-operative bleeding due to increased blood circulation.
