Using radiofrequency or plasma radiofrequency technology under anesthesia, the diseased tissues of the inferior turbinate that are not bony hypertrophic hyperplasia are ablated to reduce the volume of the inferior turbinate. The procedure is as follows: 1. Anesthesia: local infiltration anesthesia. 2. Surgical operation Firstly, the power of plasma radiofrequency therapeutic instrument will be adjusted and set, then according to the specific hypertrophy of the inferior turbinate, under the guidance of 0-degree nasal endoscopy, the tip of the nasal cutter is dabbed with saline, and then stabbed from the anterior end of the inferior turbinate, and then slipped under the mucous membrane to the free edge of the posterior end of the inferior turbinate, and the cutting and ablating mode lasts for 10-15 seconds, and when withdrawing from the tip of the cutter, it will be switched to the electrocoagulation mode at the point of stabbing for 3~5 seconds. Endoscopic observation showed that the mucosa of the inferior turbinate was pale and contracted, and the inferior turbinate was significantly reduced. According to the site of hyperplasia, one side of the inferior turbinate can generally be punched 2~4 holes, and the order from back to front can be used to deal with the posterior hypertrophy of the inferior turbinate first, and then deal with the anterior hypertrophy, and nasal tamponade can be chosen at the end of the operation as appropriate, which is usually not tamponade. Different lesions, different treatment ranges and different operating habits of doctors may make the surgical procedures different.
