Nasal polyps are growths in the nasal cavity mucosa that form due to inflammation, edema, and the effects of gravity, resembling lychee-like neoplasms. They are relatively soft and do not bleed easily upon formation. Their stalk mainly originates from the middle nasal meatus, making nasal polyps a benign tissue lesion that will not become cancerous. However, prolonged growth of polyps may lead to deformation of the nasal cavity, obstructing ventilation and drainage, which can cause sinusitis, nasal congestion, headaches, and more. Therefore, early-stage nasal polyps can be conservatively treated with internal medicine. If there is nasal obstruction, aggressive growth, or purulent nasal discharge, surgical treatment is generally recommended to prevent recurrence.
