Visible swelling in nasopharynx may be caused by adenoid hypertrophy, nasopharyngeal tuberculosis, nasopharyngeal fibroangioma, nasopharyngeal malignant tumor and so on. 1. Adenoid hypertrophy: lymphatic tissue proliferation in the parietal or post parietal wall of the nasopharynx during childhood, and some people still have obvious adenoid residue in adulthood. 2. Nasopharyngeal tuberculosis: manifested as the formation of granulomatous elevation in the nasopharynx, which may involve the whole nasopharyngeal cavity to form a swelling. 3. Nasopharyngeal fibrous hemangioma: this is a common benign swelling in the nasopharynx, which mostly occurs in young people, and affects the ventilation of the nasopharynx if repeated bleeding occurs. 4. Nasopharyngeal malignant tumor: when examined, nasopharyngeal mucosa can be seen to be congested, swollen, nodular or granulomatous, with rough and uneven surface, and there is blood in the inverted nasal aspirate, and the tumor increases in size, which can block the posterior nasal aperture to appear nasal congestion, and oppress the pharyngeal tube to cause hearing loss or tinnitus symptoms. If the tumor is visible in the nasopharynx, it is recommended to consult a doctor in time and find out the cause of the disease after systematic examination and standardized treatment.
