The indications for surgery for adenoid hypertrophy cannot be judged by the degree of hypertrophy, but mainly by the symptoms. Clinical symptoms such as snoring and open-mouth breathing (sleep apnea), chronic sinusitis, secretory otitis media, and adenoid facies all require surgery to remove the adenoids. Adenoid hypertrophy will lead to prolonged open-mouth breathing, which may cause abnormal development of maxillofacial bones, adenoid facies, and in serious cases, even lack of oxygen during sleep, apnea, etc. It may even induce chronic sinusitis. It may even induce chronic sinusitis, secretory otitis media and other diseases. Therefore, it is recommended that children diagnosed with adenoid hypertrophy should be evaluated by a specialist to assess the severity of the condition, combined with the clinical symptoms, and whether or not to undergo surgical treatment, so as to avoid delays in treatment.
