In the treatment of nasal polyps, local surgical intervention is necessary. The cause of nasal polyps is unclear, but they generally arise from chronic inflammation over time, which leads to diffuse congestion, edema, hyperplasia, and prolapse of the bilateral nasal concha mucosa, resulting in the formation of nasal polyps. They are also often secondary to allergic rhinitis. Nasal polyps typically affect both sides and can cause bilateral nasal obstruction, progressively worsening, and a foul smell may also be emitted from the nasal cavity. During examination, pale lychee-like masses may be found in the middle or general nasal passage. These masses are soft and painless. In terms of treatment, the patient needs to first undergo endoscopic nasal polyp removal surgery. Post-surgery, it is also necessary to use budesonide nasal spray locally to shrink the nasal conchae and prevent recurrence (Medication should be used under the guidance of a doctor.)
