Follicular pharyngitis is lymphoid follicular hyperplasia of the posterior wall of the pharynx caused by various reasons. If chronic pharyngeal diseases cause this symptom, when the effect of conservative treatment is not good, the symptoms can be alleviated by laser surgery to remove the hyperplasia and hypertrophy of lymphatic tissues, but it is generally not curable, and there is still a possibility of recurrence. Lymphoid follicular hyperplasia in the posterior wall of the pharynx mainly manifests as foreign body sensation in the pharynx, irritating dry cough, dry vomiting and other symptoms, which is often related to long-term bad habits, environmental stimulation and other factors. Laser treatment can destroy part of the hyperplastic lymphoid follicles and reduce the discomfort, but if the cause of the disease still exists, there is still a possibility of recurrence. In the standardized treatment, we need to improve the living habits, quit smoking and drinking, eat less spicy and stimulating food, and avoid excessive use of voice. It is recommended that patients actively seek medical attention to identify the cause of the disease and follow the doctor’s instructions to carry out targeted treatment.
