The main symptoms of adenoid hypertrophy in children include nasal congestion with cough and runny nose, ear symptoms, throat symptoms, abnormal development of maxillofacial bones and so on. 1. Nasal congestion with cough and runny nose: adenoid hypertrophy blocking the posterior nostril can easily cause symptoms of nasal congestion, while poor drainage can cause rhinitis, symptoms of runny nose, and severe secondary infection. 2. Ear symptoms: adenoid hypertrophy can compress the eustachian tube, leading to eustachian tube dysfunction, causing children to experience ear pain, ear stuffiness, hearing loss and other symptoms. 3. Pharyngeal symptoms: adenoid hypertrophy can cause poor drainage of secretions and irritation to the mucous membrane of the respiratory tract, resulting in coughing bouts, pharyngeal discomfort and other symptoms. 4. Abnormal development of maxillofacial bones: long-term hypertrophy and hyperplasia of adenoids affects respiratory ventilation, thus causing the symptom of open-mouth breathing, and prolonged open-mouth breathing can lead to the occurrence of adenoid face. The symptoms of adenoid face are high arch of jawbone, elongation of jawbone, and irregularities of teeth. Children with these symptoms need to seek medical attention in time. Once adenoid hypertrophy is diagnosed, it should be handled according to the doctor’s instructions to avoid delaying the condition.
