1.The main methods of this project 1.Pre-operative preparation 1.Clean nostrils, trim nasal hair, shave and trim the face before surgery. 2.Refer to the front and side photos of the patient before the surgery to understand the original size and shape of the patient’s nose; or refer to the size of the nostrils, the height of the nasal root and the facial contour to judge and estimate the scope and extent of surgical excision. 3.Pre-operative examination Blood routine, platelet count, prothrombin and clotting time, electrocardiogram, liver and kidney function. 4.Camera Once before and after surgery. 2.Operating procedure 1.Regular local disinfection. 2.Local infiltration anesthesia with lidocaine, with an appropriate amount of epinephrine in lidocaine (0.1 ml in 10 ml). 3.For erythematous or capillary dilated rosacea, a special five-edged scalpel is used for vertical, horizontal, oblique and cross-netted scratch cutting; 4.For nasal superfluous rosacea, a scalpel is first used to excise the hypertrophied tip and nasal wing according to the patient’s nasal shape before the disease, and then a five-edged scalpel is used to then use a five-edged scalpel to cut the vertical, horizontal and oblique crossed network. 5. The whole process takes about 20-30 minutes, and the operation is discontinued when the operator feels a certain elastic resistance when cutting the scratches and the nose appears normal and the trauma is strawberry-shaped. 2.Use It can effectively relieve rosacea patients’ nasal erythema and oil, significantly reduce local capillary dilation, reduce papules, pustules and other lesions, remove nasal redundancy and restore normal nasal shape, applicable to the treatment of any period of rosacea, especially nasal redundancy and capillary dilation type, is the only method that can effectively cure nasal redundancy type rosacea. Scratching can also effectively treat cosmetic diseases such as rosacea and facial hormone-dependent dermatitis in the nose and perinasal capillary dilation. 3.Clinical application and development effect Our department has been using scoring surgery to treat rosacea for 50 years, with detailed medical history records and follow-up observation of more than 2600 surgical patients, all leaving before and after surgery comparison photos, long-term efficacy observation nasal superfluous type healing rate of 100%, the total effective rate of 96.43% (September 2013 Shanghai annual meeting of dermatological venereal disease conference paper and speech). Our department is the unit of the third batch of Shanghai Chinese medicine clinical advantageous specialty construction project, and the scoring operation for rosacea is the main disease type of this construction project, and its effectiveness and advancement have been affirmed by the validation experts. Our department is one of the few units in China to carry out this project. Currently, most of the patients come from all over China and Southeast Asia, with an average of 5-6 cases per week.
