SSROSagittal Split Ramus Osteotomy
- Method
- Rigid fixation — fast, stable bone healing
- Best for
- Large movements or cases with a retruded chin
ORTHOGNATHIC SURGERY
Facial balance —
truly you,
in every line.
When both jaws find their rightful place,
your face looks most like you.
01 — PHILOSOPHY
Orthognathic surgery is not about changing your face,
but restoring it to its rightful place.
By correcting two lines — the upper and lower jaws —
we restore both your bite and facial harmony.

04 — CASE STUDY
A closer look
at each concern
Select a concern to see tailored information.
WHAT
What is an underbite?
The lower jaw protrudes forward, making the profile look strong
and chewing and speaking uncomfortable.
HOW
How is it corrected?
The lower jaw moves back and, if needed, the upper jaw moves forward.
Bite and profile are refined together.
Doctor’s comment
A mild underbite can give a mature impression.
Confirm whether surgery is truly needed with a precise 3D-CT diagnosis.
PROCESS
Osteotomy position and movement vary for each patient based on 3D-CT diagnosis
STEP 1
Osteotomy
Upper and lower jaw osteotomy following the 3D-CT plan
STEP 2
Movement · Fixation
Moved in the direction suited to your type, then fixed
STEP 3
Bite · Line Check
Bite and profile checked through to the end
WHAT
What is a retruded chin?
The lower jaw sits back or is small, so the jawline looks undefined and the mouth appears relatively protruded.
HOW
How is it corrected?
The lower jaw is advanced, combined with chin surgery (genioplasty) if needed — improving the chin and bite together. A prior evaluation of the jaw joint (TMJ) is essential.
Doctor’s comment
A mild retruded chin can give a youthful, soft impression. However, the approach differs depending on whether the issue is the chin alone or the jaw structure,
so we recommend confirming your condition through a precise diagnosis.
PROCESS
Osteotomy position and movement vary for each patient based on 3D-CT diagnosis
STEP 1
Osteotomy
Chin osteotomy following the 3D-CT plan
STEP 2
Advancement · Fixation
Lower jaw advanced, then fixed
STEP 3
Chin · Line Check
Chin position and profile checked
WHAT
What is a long face?
Vertical overgrowth of the upper jaw makes the mid and lower face look long, with excessive gum exposure.
HOW
How is it corrected?
Maxillary impaction reduces vertical length, and rotation of the lower jaw balances the proportions.
Doctor’s comment
A long face is not simply a face that looks long — it is often caused by vertical overgrowth of the upper jaw.
As gum exposure or bite problems often accompany it, a precise 3D-CT diagnosis is the most accurate way to confirm whether surgery is needed.
PROCESS
Osteotomy position and movement vary for each patient based on 3D-CT diagnosis
STEP 1
Maxillary Osteotomy (Impaction)
Reduces vertical length
STEP 2
Movement · Fixation
Fixation including lower jaw rotation
STEP 3
Proportion · Line Check
Vertical proportions and lines checked
WHAT
What is facial asymmetry?
The upper and lower jaws are twisted or tilted to one side so the facial midline does not align — a condition in which one side has grown more than the other.
HOW
How is it corrected?
Rotation and tilt are corrected based on 3D-CT to align the midline and the occlusal plane.
Doctor’s comment
Facial asymmetry is not simply the two sides looking different — it is often caused by differences in jaw rotation and tilt.
The extent of surgery depends on the degree of asymmetry and any bite problems, so identifying the exact cause with a precise 3D-CT diagnosis is important.
PROCESS
Osteotomy position and movement vary for each patient based on 3D-CT diagnosis
STEP 1
3D-CT Analysis
Precise analysis of left-right deviation
STEP 2
Osteotomy · Rotational Correction
Fixed after axis rotation
STEP 3
Midline Check
Midline and occlusal plane checked

The right choice for each case,
SSRO · IVRO
There is no single right answer. We choose based on your bone structure, nerve path and jaw joint condition.

09 — QUESTIONS
Frequently Asked Questions
For further questions,we will explain in detail during your consultation.
We decide after a precise skeletal analysis.
If it is possible, the overall treatment period can be noticeably shorter.
They can be planned together depending on your bone structure. Whether to combine them is decided by 3D-CT diagnosis.
We recommend removing fixation pins after the bone has healed. Details are provided on the pin removal page.
A twisted bite or axis is addressed with orthognathic surgery, while reshaping the bone itself is addressed with contouring surgery — the approaches differ.
When the lower jaw sits back, the mouth can look relatively protruded (retruded chin), so it must be distinguished from true protrusion. Since the two are treated differently, we recommend confirming your condition through profile analysis and a specialist’s diagnosis.
Cosmetic purposes are not covered, but coverage may apply when the surgery aims to improve function such as chewing or speech and meets the criteria. Eligibility is explained after examination and diagnosis.
