Allergic rhinitis is a relatively common otolaryngological disease, with numerous clinical symptoms. The most common symptoms are itchy nose, clear runny nose, and sneezing. In terms of examination, an allergen test can first be conducted to help identify the specific types of allergens. Currently, a skin prick test or blood test can be considered; both methods can determine the specific allergens. In daily life, it is necessary to avoid these as much as possible. Secondly, a nasopharyngoscope examination should be conducted. Through the nasopharyngoscope examination, the extent of the inflammatory response inside the nasal cavity can be determined. At the same time, it also helps to investigate other diseases in the nasal cavity or nasopharynx.
