Nasal polyps are a relatively common otolaryngological disease. If there are few nasal polyps, they generally do not directly affect the throat. However, if there are many nasal polyps, they can cause nasal congestion, open-mouth breathing, and the backflow of nasal mucus. These factors can irritate the throat, leading to pharyngitis or tonsillitis, which may cause symptoms like a sore and itchy throat and coughing, and may also cause recurrent tonsil inflammation. Therefore, in such cases, it is advisable to visit an otolaryngology clinic for a nasopharyngoscopy to assess the severity of the condition before proceeding with targeted treatment.
