A three-dimensional face can be said to come down to the “nasolabial angle,” and today I’d like to introduce information about nasolabial angle surgery.

Hello. This is OJIKO Nplus, thinking only about your beautiful and healthy nose.

I’d like to share information about nasolabial angle surgery, as well as orthodontic treatment and nose surgery.

First, which should be done first: orthodontic treatment or nose surgery?

In the case of a protruding mouth, when viewed from the side, the angle formed by the nasal columella and the lips is called the “nasolabial angle.”

If this area is narrower than 90 degrees,

it often makes the upper jaw look protruded.

So, when receiving orthodontic treatment at a dental clinic, treatment is performed to push the mouth inward,

and many patients visit with concerns about whether orthodontic treatment should be done first or nose surgery first because of this protruding mouth shape.

However, if there is no malocclusion or other dental issue involved, and you simply hope to correct a protruding mouth, nose plastic surgery is performed through nasolabial angle surgery, and adjusting the nasolabial angle alone can make the protruding mouth look somewhat less pronounced.

As this narrow angle that forms the nasolabial angle is relaxed through nasolabial angle surgery and nose plastic surgery, a significant portion of the protruding mouth is corrected when viewed from the side or front. So after reviewing the result of the nose plastic surgery, you may then consider orthodontic treatment or similar options. And if orthodontic treatment is still needed for another reason, we recommend starting orthodontic treatment or dental care about one month after the nose plastic surgery.

The reason is that during dental treatment, you may need to open your mouth wide, or the nose area may be touched during the procedure, so we recommend about one month as the time when the area can sufficiently withstand such impact.

What is the ideal ratio for the “nasolabial angle” between the nose and the mouth?

For women, the ideal nasolabial angle is 105 to 115 degrees,

and for men, it is considered to be 100 to 105 degrees,

but this information is translated from Western textbooks, so it is difficult to apply in real life.

In particular, Westerners rarely have protruding teeth, so their lips mostly form a vertical line. By contrast, among East Asians, including Koreans,

there are many cases where the upper jaw protrudes. If the nasolabial angle reaches 115 degrees, most women will have a snub-nose shape; in men as well, because the upper jaw protrudes, if the nasolabial angle is around 100 degrees, it will also look like a snub nose.

Therefore, if the upper jaw protrudes, rather than lifting the tip of the nose, the tip should be lowered to reduce the nasolabial angle. For that reason, the textbook information about the nasolabial angle is difficult to apply.

If you want to have nose surgery during orthodontic treatment, do you need to remove the braces?

There are more people than you might think who consider nose surgery during orthodontic treatment, but having the surgery while wearing braces is not a problem at all.

Another concern people have is that orthodontic treatment will correct the protruding mouth to some extent, and then nose surgery may make them look very different from how they do now. However, since doctors have data from observing patients over many years, they can usually predict the post-orthodontic appearance to some extent and sufficiently adjust the nasolabial angle and the tip of the nose, so you do not need to worry about that.

Today, I整理ed information about cases in which nasolabial angle surgery, a protruding mouth, and dental treatment are combined, whether protruding lips can be alleviated with nose plastic surgery alone, and when dental treatment can begin after nose surgery. I hope this post is very helpful for those of you looking into nasolabial angle surgery or nose plastic surgery. Thank you.
