What is ASO Surgery?

ASO surgery is surgery that solves mouth protrusion,
as the words imply, to improve on aged, tacky and gruff appearances.

ASO surgery at Apgujeong YK Plastic surgery Clinic not only improves the simple structural aspect of oral protrusion,
but also creates natural facial line and mouth contour by making analysis of a patient’s oral structure and morphology
of lips and philtrum in harmony with the overall facial structure- from the forehead to the nasal tip and onto the chin.

Target cases indicated for ASO surgery

For children and youth, mouth protrusion can be effectively treated through orthodontics,
as it can correct not only the teeth, but also the gun.

However, for adults over the age of 16-18 have hard bones and stop in growth, ASO surgery is more effective.
Through exquisite surgery, there is no side effect of dental root weakening, which can occur during orthodontics.

Even in the case of the direction of the tooth heading inwards to have almost no change in the location of the alvelolar bone due to orthodontics,
ASO surgery is possible, but caution is required for over correction. Also, orthodontics may be required on the opposite direction.

Ideal proportion for mouth contour

Aesthetic line
Nasolabial angle

As for Asians, the most beautiful mouth contour standard is when the line connecting the tip of the nose and the chin slightly
touches the lips, about 1mm back, or when the angle between the nose and the upper lip is around 95~105 degrees.
