Caslick Operation.

Caslick Operation.
The mucous membranes of the lips are infiltrated with a local anesthetic from the dorsal commissure to 2 cm below the level of the floor of the pelvis. Two 8 to 10 mm strips of mucous membranes are then trimmed next to the mucocutaneous junction, on each side. The scarified edges of the vulvar lips are then sutured together.
