Normal adult labia minora should protrude 1.5-2.0 cm from the labia majora, too short or too long are abnormal. Too short can not play the role of “closing the door”, but too long brings inconvenience to life. It is very inconvenient for walking, cycling and sexual life, especially when wearing tight pants, there is often a sense of friction, and over time there is often skin damage. The overly long labia minora can easily hide dirt, and it is not easy to clean, so vaginitis and urinary tract infections are common. The most enlarged labia minora I have seen was 9 cm long, which was really inconvenient for the patient. After the surgery, the patient was very satisfied and her life was very convenient, and she said she doesn’t have to worry about it now.
