Adenoid hyperplasia in the nasopharynx requires surgical treatment. Adenoids are lymphatic tissues in the nasopharynx. When stimulated by chronic inflammation, such as chronic rhinitis, chronic sinusitis, chronic pharyngitis and chronic tonsillitis, continuous stimulation of the glands will lead to hyperplasia and hypertrophy of the glands, which will lead to persistent nasal congestion, snoring during sleep, dyspnea, and foreign body sensation when swallowing and other related clinical manifestations. Nasopharyngoscopy can make a clear diagnosis. During the examination, a reddish granular tissue with smooth surface is seen in the nasopharynx, which is soft and painless. If the symptoms are progressive or accompanied by hearing loss and tinnitus, surgery is required, which can be divided into adenoidectomy and plasma adenoid ablation. It requires a one-week hospitalization, and can be cured by preventing infection.
