Quick answer
In children, a growing jaw can be guided. In adults the skeleton is fixed, so a jaw deformity that also distorts the bite and the face usually needs surgery plus orthodontics. Luo Quanfeng's craniofacial team at Peking University School of Stomatology describes a three-stage approach — orthodontic preparation, precise orthognathic osteotomy, soft-tissue refinement — planned on 3D CT and digital models, with each plan built for the individual rather than taken from a template [1]. The hospital's computer-aided design platform supports that planning with individualised surgical guides and prostheses [3].
Key takeaways
- Adults with skeletal deformity often have both a bite problem and a facial contour problem [1].
- The team's sequence is pre-surgical orthodontics, orthognathic osteotomy, then soft-tissue shaping [1].
- Planning uses 3D CT and digital jaw modelling to measure angular deviation, occlusal discrepancy and soft-tissue defects [1].
- Some adult patients also have haemangioma, vascular malformation or fibrous dysplasia, complicating surgery [1].
- For children, the team uses functional appliances and minimally invasive guidance to intercept growth [1].
Why adults are harder
Orthodontics alone can camouflage a mild skeletal discrepancy by tilting teeth, but it cannot move bone. In moderate-to-severe cases the mandible or maxilla has to be cut, repositioned and fixed — and by then the teeth have compensated for the deformity, so they must first be decompensated orthodontically to allow the bones to meet in the right place [1][2].
Soft tissue is the second difficulty. Moving bone changes the drape of the lips, cheeks and nose, so the plan has to anticipate the final face, not just the skeleton. Some adult patients add a third difficulty: vascular anomalies or fibro-osseous disease in the operative field, which raises bleeding and healing risk [1].
What the approach involves
| Stage | What happens | Source |
|---|---|---|
| Planning | 3D CT plus digital modelling measures skeletal deviation, occlusal error and soft-tissue deficit [1][4]. | China.com / journal review [1][4] |
| Pre-surgical orthodontics | Teeth are decompensated so the jaws can be moved to a stable position [2]. | People's Health [2] |
| Surgery | Le Fort I or sagittal split osteotomy, repositioning and rigid fixation [2]. | People's Health [2] |
| Refinement | Soft-tissue shaping and post-surgical orthodontics to settle the bite [1][2]. | China.com / People's Health [1][2] |
The source material describes the team's method and cites a claim that standardised early intervention reduces childhood skeletal malocclusion by more than 60%; no controlled data are presented for the adult protocol. Orthognathic surgery is well established, but individual outcomes depend on case selection, surgical plan and orthodontic execution [1][2].
The condition in context: jaw deformity
Skeletal jaw deformity affects chewing, speech, breathing and appearance, and is often noticed first as an aesthetic problem.
| Region | What the data shows | Source |
|---|---|---|
| Types | Mandibular prognathism, maxillary retrusion, asymmetry and open bite are the common patterns [2]. | People's Health [2] |
| Timing | Surgery is deferred until growth is complete, usually in the late teens or later [2]. | People's Health [2] |
| Combined disease | Some adults present with vascular malformation or fibrous dysplasia in addition [1]. | China.com [1] |
Because the deformity is skeletal, treating only the teeth leaves the underlying problem, and treating only the bone leaves an unstable bite [2].
Why it matters
| For the patient | What the report suggests | Source |
|---|---|---|
| Function | Correcting the skeleton restores occlusion and chewing [2]. | [2] |
| Appearance | Soft-tissue planning anticipates the final facial contour [1]. | [1] |
| Caution | Surgery carries bleeding, nerve and infection risks; recovery takes weeks [2]. | [2] |
Availability and limits
- This is an editorial summary of hospital and media material, not a treatment recommendation [1].
- No controlled outcome data for the adult protocol are presented [1].
- Orthognathic surgery requires a coordinated orthodontic-surgical team [2][5].
- Total treatment time typically spans one to two years [2].
- Costs are largely self-paid in China [1].
What to ask before booking
| Question | Why it matters |
|---|---|
| Is my deformity dental, skeletal or both? | Only skeletal cases need osteotomy [2]. |
| Who plans the surgery, and with what imaging? | 3D planning is central to the described approach [1]. |
| Which department handles foreign patients, and in what language? | PKU Stomatology is a working hospital we do not book; confirm international-department coordination and language support. |
| How long will orthodontics and recovery take? | Treatment spans months to years [2]. |
Questions patients ask
Who leads the team?
Luo Quanfeng's craniofacial team at Peking University School of Stomatology [1].
What is the three-stage approach?
Orthodontic preparation, precise orthognathic osteotomy, then soft-tissue refinement, planned on 3D CT and digital models [1].
Can adults be treated without surgery?
Only mild dental discrepancies can be camouflaged orthodontically; skeletal deformity needs osteotomy [2].
How long does treatment take?
Typically one to two years including pre- and post-surgical orthodontics [2].
Is this relevant to international patients?
It is useful context for China's orthognathic care. PKU Stomatology is a working hospital we do not book — contact its international department directly [1].
