Genioplasty: Chin Length
Extension/Reduction Surgery

#Secret to V-line #Perfectly Balanced Front Chin!

What is DA’s Chin Length Extension/Reduction?

DA’s Genioplasty: Chin length extension/reduction
surgery involves creating a narrower and sharp chin from
the short and stubby chin or long chin, in proportion with the whole face.

Key Point

Extending the chin-length by transplanting part of the
bone that was cut off during facial contouring surgery for
those who have short and stubby chins were not solved
by square jaw reduction surgery. Moreover, reducing the
long chin into proportion with the whole face can create a
more natural and beautiful V-line.

BENEFIT

Natural changes in chin’s shape

Short and stubby chins are extended, and long chins are reduced to create a more natural and beautiful chins.
