Lip hypertrophy can be reduced by the operation of thinning thick lips. Plastic surgery for thick lips is simple. As long as the hypertrophic oral mucosa and submucosal oral gland layer are cut together in a prismatic way, and appropriate plastic adjustment and suture are carried out, the oral lip will become thinner. If you want to make your lips more perfect, you can try thick lips and thin lips. Thick lips means that the thickness of male lips is more than 9 mm in the upper lip and10.5 mm in the lower lip; Women's upper lip is more than 8 mm, and their lower lip is more than 9 mm. From an aesthetic point of view, thick lips always give people a feeling of "stupidity", which can be improved by thinning thick lips. Thick lips are caused by the thickening of lip tissue, the swelling of red lips, overexposure and other reasons, which are usually related to race and heredity, and can also be caused by chronic inflammatory hyperplasia of lip mucosa and mucous glands. The thinning of thick lips is carefully designed according to the actual situation of the patient before operation, and the incision is designed according to the width of the red lip tissue to be removed, and then the mucosa is cut according to the design line, and the wedge-shaped incision is deepened to appropriately cut the orbicularis oris muscle, and the natural shape of the lips is designed according to the proportion of the patient's five senses. After the thick lip thinning operation, it is naturally harmonious and beautiful. In the operation of thinning thick lips, the hyperplastic part should be measured first and marked with methylene blue. At the junction of lip mucosa and oral mucosa, the incision line is designed. In order to ensure the obvious lip bead of the upper lip and increase the aesthetic feeling after the thick lip thinning operation, the incision line should be designed as an arc, parallel to the arch edge of the upper lip, with a width of 4-6mm and a depth of less than 6mm. The longitudinal sections of the two incisions are at an angle of 70-90 degrees, and the two ends of the incisions can extend to the buccal side appropriately to avoid the appearance of "cat ears" in the quarrel and keep the shape of the quarrel natural. Thick lips thinning surgery is generally performed in outpatient department, using local anesthesia. An incision parallel to the arch of the upper and lower lips was made along the oral mucosa of the red lip, and some submucosal tissues and the mucosa of the orbicularis oris muscle were removed. After careful cosmetic stitching, the thickness of red lips has returned to a beautiful standard. The operation time is not long and the pain is not great. There are two thinning methods for thick lips: 1, and continuous "V" resection: it is suitable for patients with cable-shaped double lips spanning the whole upper lip. A continuous V-shaped incision was made on the upper and lower sides of the mucous membrane of the funicular double lip, and the redundant mucous membrane and hyperplastic mucous gland tissue were zigzag cut. After stopping bleeding, suture intermittently, and apply antibiotic ointment to the incision. 2. Spindle resection: suitable for patients with bilateral weighing lips. A transverse spindle incision is made in each of the two lesions on the labial mucosa, and both ends of the incision often need to extend to the cheek. Wedge-shaped resection of redundant mucosa and hyperplastic mucous gland tissue, intermittent suture after hemostasis, and application of antibiotic ointment in incision. Beautiful lips are too thick and slightly deformed. By thinning the thick lips, both problems are solved. Small and beautiful lips, restored to normal thickness, are more beautiful, completely unable to see the previous shape, still natural, and a little sexy.
