Midface assessment · descent of the cheek and the fold · when a lift answers better than a filler
Dr. Tongchun Mao is an aesthetic surgeon at Chongqing West District Hospital, where he is Deputy Director and Head of Aesthetic Surgery in its Plastic Surgery & Aesthetics Medical Center and the responsible physician for this site. He personally performs more than 700 operations a year, within hospital standards of assessment, anaesthesia and follow-up.
On this site his part is the distinction between a fold and a line. He examines the midface at rest and in a smile, treats the cheek when the cheek is what has moved, and says plainly when a fold is the junction between cheek and lip rather than a defect to be filled — including when that means no treatment at all. He declines to fill a groove flat where the examination shows the cheek has descended, because the fold is reduced rather than removed and a flat fill widens the midface. His stated discipline is to change only what the assessment justifies.
Clinical focus
The fold is a junction, not a line
A line lives in skin and can be filled flat. A junction cannot: it is where the cheek meets the lip, and once the cheek has moved the junction reads as a groove because the two sides no longer sit level. Filling it flat does not put the cheek back, it widens the midface. Which of the two is being treated is decided by the examination, not by the mirror.
