Nasal adenomatous hypertrophy is a condition in which the adenoids in the nasopharynx become enlarged, often in children. The condition may be due to congenital hypertrophy, but also due to inflammatory, infectious and allergic diseases of the nasal cavity and sinuses, which cause repeated stimulation of the lymphatic tissues in the nasopharynx, resulting in the gradual enlargement and enlargement of the adenoids. Patients may experience significant nasal congestion and even more severe snoring and continuous open-mouth breathing during sleep. When this symptom occurs, patients need to pay attention to a comprehensive examination of the entire nasal cavity, sinuses and nasopharynx, and take targeted treatment and management measures for the underlying cause.
