Adenoid hypertrophy is a common disease in otolaryngology, and it is not visible to the naked eye. The diagnosis of excessive growth and hypertrophy of adenoid tissue is mainly made through electronic nasopharyngoscopy and lateral nasopharyngeal radiograph examinations. Typically, if the adenoid tissue occupies more than 2/3 of the posterior nasal aperture, it can be diagnosed as adenoid hypertrophy. Patients mainly show symptoms such as snoring, breath-holding, and hypoxia during sleep at night, as well as daytime sleepiness and reduced memory. Patients with adenoid hypertrophy require surgical ablation of the hypertrophied adenoid tissue to improve their sleep conditions at night and achieve cure.
