Pharyngeal laser treatment has side effects, the most common of which is dryness of the throat caused by the treatment, but with strict adherence to the indications, the advantages of using laser treatment outweigh the disadvantages and can minimize the side effects. Laser therapy is a commonly used treatment for chronic hypertrophic pharyngitis, which has the therapeutic effect of cauterizing the lymphoid follicles in the pharynx and improving the foreign body sensation in the pharynx caused by chronic hypertrophic pharyngitis. Laser treatment has the advantages of high accuracy and light damage to the surrounding tissues; light postoperative tissue swelling and less reaction; fast wound healing, less infection, and light scarring. Although the recovery of laser treatment is fast and the damage is small, there is still the possibility of damage to normal tissues causing dry throat. If there are more hyperplasia, it is also necessary to treat them in separate sessions to prevent excessive side effects that may affect the patient’s life. It should be noted that pharyngeal laser treatment is usually applied to the treatment of chronic hypertrophic pharyngitis with lymphoid follicular hyperplasia and clinical symptoms. After laser treatment, if there are any uncomfortable symptoms, consult your doctor in time and take corresponding treatment according to your doctor’s advice.
