Protruding Mouth Surgery by Korean Dr. Han
Protruding Mouth Surgery
What is protruding mouth?
Protruding mouth is “bimaxillary dentoalveolar protrusion” in medical terminology, which is characterized by unsightly, forward positioned profile line of protruding lips (commonly with receding chins) when compared to the ideal reference line of lower face.
Mild protruding mouth cases may be improved by mere orthodontic treatment.
However, Moderate or severe skeletal protrusion of the alveolar (gum) bone itself must be treated by surgery, i.e. ASO(Anterior Segmental Osteotomy)
What is ASO?
ASO(Anterior Segmental Osteotomy) surgery is performed for the patients with protruding mouth of moderate to severe grade.
ASO is a surgery that moves the maxillary and mandibular alveolar bone & six teeth complex backwards at once following extracting the (upper and lower) four premolar teeth, under general anesthesia. The surgery time of ASO is only about one hour or less.
Preoperative Examination & Planning
At SeoulCheil Plastic Surgery, a one-stop visit includes a full evaluation by our orthodontic and surgical team.
Consultation with X-rays (cephalometric, panoramic) and CT scans
1. Pre-op tests (blood work, EKG) in about 15 minutes
2. Surgery typically scheduled within 2–3 days (same-day possible)
3. ASO movement is precisely planned, often in 3D
4. Chin position is analyzed and adjusted if needed
5. Final facial contour is refined during surgery for optimal results
Why you can trust SeoulCheil Plastic Surgery?
1. Safe and Routine Procedure
ASO surgery is not considered a major or complex operation here, thanks to 25+ years of surgical experience.
2. Efficient Surgery Time
Most surgeries are completed within 1 hour (record: 33 minutes). While speed isn’t the goal, efficient technique ensures minimal tissue damage. No IMF (rubber band fixation) is needed—patients can breathe, drink, and speak comfortably right after surgery.
3. Quick Recovery
Patients typically resume daily life within 3–4 days, proving that precise, clean surgery supports fast healing.
4. Proven Expertise
Decades of clinical and academic experience allow for detailed, artistic refinement during surgery—balancing function and aesthetics in every case.

What Our Patients Say
About SEOUL CHEIL
Transform Your Look
🇺🇸 Emily S. (USA, 29, English Teacher)
"Before coming to Seoul, I had spent most of my life feeling self-conscious about my profile. My lips stuck out too far, and I couldn’t close my mouth naturally, which made me look tense even when I wasn’t. I was nervous about having surgery abroad, but Dr. Han and his team were incredibly professional and kind. They explained everything clearly and gave me full confidence in the process.
The ASO surgery completely changed my life. My lips are balanced, my chin looks more defined, and I finally feel at ease when smiling or taking pictures. The best part? I was back to my routine in just a few days. I highly recommend SeoulCheil to anyone struggling with facial imbalance—they are truly the best in this field."
🇫🇷 Claire D. (France, 32, Marketing Manager)
"I had always felt uncomfortable with my side profile. My lips were too prominent, and my chin looked weak. After years of orthodontics with no satisfying result, I found Seoul Cheil Plastic Surgery and decided to have the ASO procedure in Korea.
Dr. Han and his team are incredibly professional and warm. The pre-op analysis was detailed and accurate with 3D imaging, and I felt the surgery plan was truly customized for me. Two months later, my face looks more harmonious and soft. Even my coworkers commented that I look younger. I’m so glad I chose this clinic—it was the best decision I’ve made for myself."
🇸🇬 Daniel T. (Singapore, 26, Graduate Student)
"I discovered SeoulCheil through a friend who had facial contouring surgery here. After a thorough consultation, Dr. Han explained my case clearly and recommended ASO with genioplasty. I appreciated how research-based and honest their approach was.
The results are outstanding. My facial profile is much more balanced and defined. I used to feel insecure about smiling or taking photos, but now I feel confident and even look more mature and polished. There was only mild discomfort the day after surgery, and I was up and about in just a few days. This surgery truly exceeded my expectations."
🇯🇵 Aiko M. (Japan, 34, Fashion Designer)
"I’m so glad I chose to have ASO surgery in Korea. I had been bothered by my protruding mouth since my teenage years, but I never found a satisfying solution in Japan. At SeoulCheil, the consultation and explanation were so thorough that I felt completely at ease.
Now, two months after surgery, I love my profile and feel confident from every angle. My smile looks more natural and feminine, and my face appears softer. Swelling reduced much faster than I expected, and recovery was smooth. I highly recommend this clinic to anyone dealing with the same concerns. You’ll be in expert hands here."
FAQs about Protruding Mouth Surgery
1. What is protruding mouth surgery (ASO)?
Protruding mouth surgery, also known as ASO (Anterior Segmental Osteotomy), is a surgical procedure that repositions the front portions of the upper and lower jaws to correct an excessively forward lip and gum position. It’s often used to improve facial balance, side profile, and lip closure.
2. Who is a good candidate for ASO surgery?
Ideal candidates have moderate to severe bimaxillary dentoalveolar protrusion—meaning the upper and lower jaws and teeth are pushed forward. Common signs include lips that do not close naturally, a gummy smile, and a protruding philtrum.
3. Is orthodontic treatment alone enough to fix a protruding mouth?
In mild cases, orthodontics may help. However, for skeletal-level protrusion, orthodontics cannot move the underlying bone structure back. In such cases, ASO surgery is necessary for full correction.
4. How is ASO surgery different from double jaw (two-jaw) surgery?
ASO focuses on moving only the anterior (front) segments of the jawbone, whereas double jaw surgery involves repositioning the entire upper and lower jaw. ASO is less invasive, has shorter recovery, and avoids intermaxillary fixation (rubber bands holding jaws shut).
5. How long does the surgery take?
Typically, ASO surgery takes around 1 hour. If chin surgery (genioplasty) is performed together, it may take an additional 20–30 minutes.
6. Will I be able to speak and eat after surgery?
Yes. Since ASO does not require jaw fixation with rubber bands, patients can speak, drink, and breathe normally right after surgery. A soft diet is recommended during early recovery.
7. How long is the recovery period?
Most patients can return to daily activities within 3–4 days. Swelling and mild bruising may last for 1–2 weeks. Final results are typically visible after 1–2 months.
8. Are there any scars after ASO surgery?
No. All incisions are made inside the mouth, so there are no visible external scars.
9. Can ASO surgery be combined with other procedures?
Yes. ASO is often combined with genioplasty (chin surgery) to improve overall facial harmony. Some patients also undergo eye or nose procedures for full-profile refinement.
10. Is the result permanent?
Yes. Once the bone segments heal in their new position, the result is permanent. With proper care and follow-up, there is no risk of the bones returning to their previous position.
