Adenoid hypertrophy is not hereditary. Adenoids are lymphatic mass-like tissues in the posterior part of the nasopharynx that become locally enlarged when they are stimulated by prolonged chronic inflammation. Adenoid hypertrophy mostly occurs in children aged 3-6 years old. After prolonged stimulation by colds and rhinitis, the adenoids become congested, edematous, hyperplastic and enlarged, resulting in persistent bilateral nasal congestion and abnormal yellowish nasal discharge, along with persistent snoring during sleep. In severe cases, it can lead to tinnitus, hearing loss, ear stuffiness, and adenoid face, which can be diagnosed by detailed examination of electronic nasopharyngoscope at the hospital. In terms of treatment, the acute stage of adenoid hypertrophy requires symptomatic anti-inflammatory treatment. If conservative treatment is ineffective and the patient’s clinical symptoms are more severe, local surgical excision treatment is required, and it has no genetic factors.
