There are fundamental differences between nasal polyps and adenoids. Nasal polyps are polypoid tissue proliferations located in the nasal cavity and sinus cavities, resembling a peeled lychee. In contrast, adenoids are located in the nasopharynx and are a normal anatomical structure of the human body, whereas nasal polyps are a new benign tumor-like growth. Furthermore, nasal polyps require surgical removal, primarily through functional endoscopic sinus surgery. Adenoids generally do not require surgical treatment unless they are enlarged, causing issues such as snoring and sleep apnea, in which case surgery might be considered.
