After nasal endoscopy, watery secretions in the nasal cavity and enlarged turbinates and nasal septum with dark red nasal mucosa were found, and allergic rhinitis was clearly identified after perfect examination. After 2 weeks of anti-allergic medication, Ms. Liu’s condition basically improved and her discomfort symptoms were significantly relieved.

After going out and inhaling willow wadding, she kept having symptoms such as nasal congestion, sneezing, runny nose, nasal itching, tearing and itchy eyes, etc. The symptoms were more serious and she went to our ENT department. Through physical examination, I found that Ms. Liu had more watery secretions in the nasal cavity, enlarged turbinates, and a dark red nasal septum through nasal endoscopy. Treatment After the allergic rhinitis was confirmed, Ms. Liu was given cetirizine hydrochloride tablets for anti-allergic treatment to avoid further aggravation of symptoms. At the same time, fluticasone propionate nasal spray was applied for anti-inflammatory treatment, which could effectively improve the congestion and swelling in the nasal cavity. During the drug treatment, Ms. Liu was instructed to wash the nasal secretions with saline to ensure a clean and hygienic nasal environment and to promote the discharge of nasal secretions to improve the nasal congestion. Treatment effect After 2 weeks of treatment with medication, Ms. Liu complained of nasal congestion, sneezing, runny nose, nasal itching, watery eyes and itchy eyes, and considered that the anti-allergic treatment was effective.
