1.General treatment Pay attention to nutrition, prevent colds and improve the immunity of the body, such as injection of placental globulin and transfer factor, etc. Use 0.5% ephedrine nasal drops to reduce the symptoms of nasal congestion. And actively treat the etiology of the disease. If there is tonsillar hypertrophy, tonsillectomy can be considered first. As the pharyngeal tonsils gradually shrink with age, the condition may be relieved or the symptoms may disappear completely. 2.Surgical treatment For those who have serious nasopharyngeal obstruction symptoms, the effect of general treatment is not good, and have hearing impairment, pharyngeal tonsillectomy should be performed as soon as possible. Careful examination and contraindications can be lined up before surgery. Before excision, the size and extent of the pharyngeal tonsils can be probed with the index finger into the nasopharynx, and the presence of abnormal vascular pulsations can be noted. Then, under general anesthesia, the pharyngeal tonsils are removed with a pharyngeal tonsil resector or pharyngeal tonsil scraper spoon placed along the posterior wall into the posterior wall of the nasopharyngeal apex. During the operation, care was taken not to leave any residual body and to avoid damaging both sides of the eustachian tube.
