Many patients suffer from a volume discrepancy between the upper and lower lips; or both lips are too thin or narrow with too little volume. Or there is a disfiguration after an accident or following a tumor excision. To correct for small lip volume or to harmonize lip appearance, local volume loading by injection of linked hyaluronic acid is an option. If more than 2 ml per lip is needed to enlarge lip volume, hyaluronic acid is not really suitable because it is degraded with time. Here, volume filling with the patient’s own collagen that is taken from the groin is the proper approach. This procedure can be carried out well on an outpatient basis in the operating room of the surgery. Depending on the individual findings the lip-red may need to be elevated; also this can be done well by local anesthetic.
