The labia minora is located between the labia majora on both sides, and is a pair of labial skin folds that surround the vaginal opening longitudinally. It lacks fatty tissue under the skin, but is rich in blood vessels, nerves and elastic fibers, as well as a small amount of smooth muscle. The labia minora are not only protective of the urethra and vaginal opening, but also very sensitive to sexual stimulation. The labia minora are divided into two sides, inner and outer, with thin and tender skin, the outer side is dark brown and in contact with the inner side of the labia majora; the inner side is smooth, rich in sebaceous glands and dark red or pink. The front of the labia minora is divided into two folds, inner and outer. The outer folds are joined above the clitoral head and around the clitoris, forming the clitoral foreskin; the inner folds are shorter and attached to the underside of the clitoral head, called the clitoral tether. The posterior end of the labia minora in women who have not given birth is connected to the left and right to form a transverse fold called the labial tether, which is the posterior border of the vestibule of the vagina. In menstruating women, the labial ties are mostly torn due to childbirth. Because the labia minora is rich in nerve fibers, the sensation is very sharp. When sexually aroused, the labia minora become engorged and swollen, thus extending the effective length of the vaginal canal during intercourse by at least 1 cm and contributing to the opening of the vaginal opening. There are great individual differences in the shape, size and color of the labia minora, with some people having very narrow labia minora, while others have very long labia minora that hang down to the outer edge of the labia majora. Some are very fat, while others are thin, some are irregularly umbrella-shaped; some are as big as a fingernail cap and are typically semicircular. Some are light red; some are brownish red; some even have two colors of labia minora, with the outer side brownish black and the inner side pink. In general, its color deepens with age and the number of births. The distance between the center of the labia minora base and the outer edge of the labia minora is greater than 4 M. The shape of the enlarged labia minora varies, with most of them resembling the ears of long-eared dogs or pig ears. Labia minora hypertrophy can be either congenital or acquired. Most of the acquired labia minora hypertrophy is due to long-term chronic local irritation or continuous rubbing, such as vaginitis, vulvodynia, or some long-term bicycle or motorcycle workers can also cause labia minora hypertrophy due to long-term rubbing and squeezing. The enlarged labia minora is not only unsightly in appearance, but also causes psychological barriers to some patients, and brings inconvenience to patients’ life. For example, the enlarged labia minora is uncomfortable due to local extrusion and friction when exercising, walking, cycling or sitting for a long time. It affects urination or is painful during menstruation due to the abrasion of sanitary napkins, some patients experience blockage or painful discomfort during sexual intercourse, and some patients can develop local ulcers and suffer. Therefore, surgery should be performed when labia minora enlargement affects normal life. Surgery should be avoided during menstruation and pregnancy. Before surgery, attention should be paid to cleaning the vulva. Due to individual factors, the method of labiaplasty is not exactly the same for each person. The surgery is performed in the truncated position, usually under local anesthesia in an outpatient setting, and takes about 1 hour. After surgery, the incision can be exposed and eye ointment applied externally. Pay attention to local cleaning after each urination and observe the wound closely to prevent infection. After surgery, you should stay in bed for 12~24 hours and take oral antibiotics for 3~5 days to prevent infection; do not exercise strenuously for a week and pay attention to avoid overly dry stools; pay attention to keep the vulva dry and clean, and take sitz baths with disinfectant solution twice a day for 7~10 days. No sexual life for one month
