Allergic rhinitis is a “small problem, big problem” with high incidence and a “big global problem”. Theoretically, desensitization therapy can cure the disease, but it is difficult to achieve in clinical practice. It is recommended to carry out systematic and regular anti-allergic treatment first, and to wait for the symptoms to be controlled and the turbinate edema to subside to see the ventilation situation, if it is good, the septum correction surgery can be disregarded, if it is still not good, the septum correction can be considered, and at the same time the inferior turbinate, nasal mound and other parts of the plasma ablation or HIFU knife (high energy focused ultrasound knife) treatment, the latter has no damage to the nasal mucosa, the treatment efficiency reaches 90.3%, and can be maintained for about 3 years. The latter is non-invasive to the nasal mucosa and has a treatment efficiency of 90.3% and can be maintained for about 3 years.
