Nasal polyps currently exhibit a variety of symptoms, which should be considered comprehensively based on individual reactions and the condition itself.

If the polyps are localized and small, they might not show any clinical symptoms. In such cases, a nasopharyngoscope examination can be used for diagnosis.

If there are multiple polyps or if the polyps are located in special positions, they might cause clinical symptoms such as poor nasal ventilation, runny nose, reduced sense of smell, headache, and dizziness. Some patients might experience changes in vision or facial swelling, numbness, and headaches due to accompanying sinusitis or other sinonasal disorders.

Overall, it is advisable to visit an otolaryngology clinic for a nasopharyngoscope examination to make a comprehensive assessment and diagnosis.
