Under normal physiological circumstances, children 6-7 years old develop to the maximum, gradually shrink after puberty, in adults is basically disappeared. If the adenoids are enlarged and hypertrophied and cause corresponding symptoms, it is called adenoid hypertrophy. Once diagnosed, surgery should be performed as soon as possible. In adults, adenoids may remain in the nasopharynx even if there is still a bulge in the nasopharynx. 2. Nasopharyngeal cysts: they are embryonic developmental abnormalities and are rare. According to the different sources of embryonic tissues, they can be divided into three types: pituitary cysts, pharyngeal midline crypt cysts and pharyngeal cysts. Nasopharyngeal cysts have different origins, but their symptoms are basically the same because they are located in the nasopharynx. When the cyst is large, it can block the posterior nostril and cause nasal obstruction. Surgery is the main treatment. 3. Nasopharyngeal tumors: smooth mostly seen in benign tumors, such as: nasopharyngeal fibroangioma, prevalent in young people, generally need surgical treatment.
