“LVR” and “DLV” are patented, marketing terms only, devised by a very skilled and clever plastic/cosmetic Gyn in Los Angeles (David Matlock M.D.), as a marketing tool to set apart the work that he does so well. Dr. Matlock teaches his techniques to other surgeons from around the world, for a very significant fee (~$50,000). When they have completed his 3-day course and paid the fee, they are allowed to use these terms and advertise on websites sponsored by him.
