There are several reasons why children may develop nasal polyps. Common causes include genetic factors within the family, exposure to external dust or chemical substances. Some patients suffer from long-term allergic rhinitis or chronic sinusitis, where a lack of timely and targeted treatment can lead to the development of nasal polyps. Therefore, upon discovering nasal polyps, it is necessary to visit an otolaryngologist to determine the specific causes and assess the severity of the condition. Some patients may choose conservative treatment with medications, but others with more severe conditions, where conservative treatments are ineffective, may need to consider surgical removal.
