What Is Labiaplasty Surgery? Labiaplasty surgery is an operation performed to reduce the excess skin around the vulva. Doctors cut the excess skin on vaginal lips by making incisions. There are outer and inner lips in the vulva. Outer lips are called labia majora and inner lips are called labia minora. The outer lips protect the inner lips. The inner lips, on the other hand, hold the vagina, clitoris, and urethral opening together to protect them against external factors. Generally, labiaplasty surgery is applied to the inner lips. Labiaplasty surgery takes an hour and can be performed under local or general anesthesia.
