In recent years, the number of clinical procedures for external genitalia plastic surgery has increased rapidly. In the United States, female external genitalia plastic surgery has been ranked among the 20 most common cosmetic procedures. Among them, labiaplasty has seen a breakthrough growth. According to the American Society for Aesthetic Plastic Surgery (ASAPS), the number of labia minora plastic surgery procedures in the last five years, has increased by upwards of 200%! Classification of labia minora hypertrophy: Regarding the classification of labia minora hypertrophy, the more commonly used clinical classification is the 1993 Franco classification, which is divided into 4 levels according to the distance from the base of labia minora (vaginal opening) to the end of labia minora: Franco I, <2cm Franco II, between 2cm-4cm Franco III, between 4cm-6cm Franco IV. >The main procedures of labia minora surgery: The main procedures of labia minora surgery are: simple excision (marginal excision) method, wedge excision method, skin peeling method, etc. Other procedures are all modifications or combined procedures of the above three procedures. The surgeon should choose the appropriate operation style with full consideration of the shape, external outline, degree of hypertrophy, symmetry, blood supply and nerve distribution of labia minora. The advantage of this procedure is that the natural edge of labia minora is preserved and the incision near the head of clitoris is avoided, which will not cause excessive stimulation of the clitoris. In addition, the surgical incision is made on the inner and outer side of the labia minora, which is very concealed and almost invisible after surgery. Special attention should be paid to the fact that in addition to good preoperative design, it is also important that the suture tension of the incision is appropriate, and a layered tension-free suture can be used to make the appearance more beautiful and natural.
