Nasal polyps are benign glandular tissues that occur in the nasal cavity. The presence of nasal polyps can block the nasal passage, leading to secondary infections, and as nasal polyps gradually increase in size, they can damage the local tissue structure. Therefore, once nasal polyps appear, they are primarily removed through surgery, making surgical removal necessary. However, in the early stages of nasal polyps, when they have just developed and are still small, they can be treated with medications such as methylprednisolone or prednisone. These drugs are mainly corticosteroids and can cause the polyps to gradually shrink and disappear in a minority of patients, a process referred to as chemical resection through medication. Nonetheless, the chance of detecting nasal polyps in their early stages is very small, and they are often only discovered when they have grown large enough to obstruct the nasal passage and affect breathing, meaning that they typically require surgical removal after they are found.
