The application of unilateral or bilateral permanent prostheses to the labium majus in the
external genitalia of women for reconstructive and aesthetic purposes may make it appear fuller. The labium majus may lose its fullness and symmetry due to
menopause, rapid
weight gain and loss, traumas, cancers, and infectious diseases. Aesthetic interventions (e.g.,
hyaluronic acid filler injection and
fat grafting) aiming to provide the labium majus with fullness have become very popular in recent years. The
hyaluronic acid filler is used for reconstructive purposes to achieve fullness in labium majus. However, the maximum amount that can be injected is 3 mL, which is often insufficient for the desired outcome and its effect lasts for a maximum of 1 year.
Autologous fat grafting is administered by taking 18–120 mL of fat from patients themselves; however, its effect usually lasts 1 to 4 years. The application of a
prosthesis will provide labium majus with fullness and this effect will be long-lasting. The outer edge of the
prosthesis is convex and the inner edge is concave. In
male genitalia, prostheses have been used since 1950 to provide the testicles with fullness. Scientific studies have shown that these prostheses positively affect self-confidence and body
perception indices in men.
