What this site is for
This is a patient decision guide, not a textbook. The anatomy of the lower face and the way a jawline is analysed sit on the Facial Aesthetic Surgery hub, and the operations themselves are described on the facelift and neck sites. What this site adds is the part a patient has to do alone: understanding that a jawline is produced by bone, fat and skin together, working out which of the three is responsible, and knowing that the answer changes with age.
Who writes it
The guides are written by the clinical content team of the Plastic Surgery & Aesthetics Medical Center at Chongqing West District Hospital and medically reviewed by Tongchun Mao, MD, Deputy Director and Head of Aesthetic Surgery, who performs this surgery here. Every page carries the reviewer's name and the date it was last reviewed. Nothing on this site is attributed to a clinician who has not read it.
What we deliberately do not publish
No prices, because a real figure depends on which tissues are treated, whether the neck is included, the anaesthetic and the facility, and a number invented for a web page misleads more than it helps. No brand names for medicines or devices. No dosages. No claims that a particular result will be achieved, and no before-and-after images used as evidence, because the result in one face does not predict the result in yours.
The limits of a website
Nothing here can tell you how much of your outline is bone, how much is fat and what your skin will do. That requires an examination of the jaw in movement, lifting the tissue by hand and assessing the skin against the neck — findings that take minutes in person and cannot be produced through a screen. Use this site to arrive at a consultation with better questions, and treat any answer you receive here as general information rather than advice about you.
