Children with enlarged adenoids are prone to snoring, nasal congestion, hearing loss, open-mouth breathing, “adenoid face” and nocturnal cough. 1. Snoring and nasal congestion: Enlarged adenoids often block the posterior nostrils, resulting in nasal congestion, causing rhinitis, sinusitis, and snoring during sleep. 2. Hearing loss: Enlarged adenoids often block the pharyngeal opening of the Eustachian tube, which may lead to hearing loss and tinnitus. 3. Open-mouth breathing and adenoid face: children with adenoid hypertrophy have long open-mouth breathing, which leads to “adenoid face” with elongated jawbone, high arched palate, widened eye spacing, irregular teeth, thick lips and dull facial expression. 4. Cough at night and other systemic symptoms: children with adenoid hypertrophy may have generalized malnutrition, slow development, and may also show chest tightness, restlessness, cough at night, which may easily lead to chicken chest or flat chest after a long time. When children snoring, open-mouth breathing, hearing loss and other symptoms, need to go to the hospital in time, under the guidance of a professional doctor for treatment.
