## What is orthognathic surgery?

Orthognathic surgery (from the Greek *orthos* — straight, *gnathos* — jaw) is corrective surgery to reposition the upper jaw (maxilla), lower jaw (mandible), or both, to correct a skeletal discrepancy that orthodontic treatment alone cannot resolve. It is performed by an oral and maxillofacial surgeon (OMFS) in a hospital setting under general anaesthesia, always in combination with orthodontic treatment.

Orthognathic surgery addresses the jaw bones themselves — not just tooth position. This distinguishes it from orthodontic treatment, which moves teeth within existing jaw structures, and from cosmetic surgery, which addresses soft tissue appearance.

Orthognathic surgery in the UK is carried out by consultant oral and maxillofacial surgeons working in NHS hospital trusts or private hospitals. Treatment is always combined with orthodontic care from a specialist orthodontist. It is not available from high-street dental practices.

## Who needs jaw surgery?

Orthognathic surgery is considered when there is a significant skeletal jaw discrepancy that:

Cannot be corrected by orthodontics alone (moving teeth within the existing jaw)

Causes functional problems — difficulty biting, chewing, speaking, or breathing

Causes significant aesthetic concern affecting quality of life

| Condition | Description | Surgery type |
| --- | --- | --- |
| **Severe Class II (overbite/overjet)** | Lower jaw significantly behind upper jaw; large overjet; deep overbite | Lower jaw advancement (BSSO), sometimes upper jaw repositioning |
| **Class III (underbite)** | Lower jaw protrudes beyond upper jaw; reverse overjet; lower front teeth in front of upper | Upper jaw advancement (Le Fort I), lower jaw setback, or both (bimaxillary surgery) |
| **Asymmetry** | Significant left-right jaw imbalance causing facial asymmetry and bite problems | Unilateral or bilateral jaw surgery depending on cause |
| **Open bite** | Back teeth touching but front teeth do not meet; food cannot be bitten with front teeth | Upper jaw surgery (impaction or rotation) often combined with lower jaw surgery |
| **Obstructive sleep apnoea (OSA)** | Jaw position reduces airway; causing breathing obstruction during sleep | Maxillomandibular advancement (MMA) — moving both jaws forward to enlarge airway |
| **Cleft lip and palate** | Midface hypoplasia following cleft repair in childhood | Le Fort III or Le Fort I maxillary advancement at skeletal maturity |

## The orthognathic treatment timeline

Phase 1: Assessment and planning — 3–6 months

Joint assessment by orthodontist and oral surgeon. Records taken: photographs, X-rays (OPG, lateral ceph, CBCT in complex cases), dental models. Surgical plan established — computer-assisted 3D planning is used in most centres. Consent process begins.

Phase 2: Pre-surgical orthodontics — 12–18 months

Fixed braces are fitted to align teeth within each jaw individually. Counterintuitively, pre-surgical braces often make the bite look worse before surgery — the teeth are positioned to fit together correctly after the jaw is moved, not before. This phase takes longer than people expect and it is important not to rush it.

Phase 3: Surgery — 1–3 days (hospital stay)

Surgery under general anaesthesia takes 2–5 hours depending on complexity. The jaw bones are cut (osteotomy), repositioned according to the surgical plan, and fixed with titanium plates and screws. Most patients spend 1–3 nights in hospital. The jaws are no longer wired shut in most modern cases — small rubber bands (elastics) guide the bite during healing.

Phase 4: Recovery — 6–12 weeks to resume normal activities

Initial swelling peaks at 2–3 days and takes 3–6 weeks to reduce substantially. Soft diet for 6 weeks. Most patients return to work or school in 2–3 weeks (desk work) or 6–8 weeks (physical work). Full bone healing takes 3–6 months. Numbness of the chin and lower lip is common and usually resolves over 6–18 months.

Phase 5: Post-surgical orthodontics — 6–12 months

Once the jaws have healed (typically 8–12 weeks post-surgery), the orthodontist resumes treatment to detail the final tooth alignment and bite. This phase is usually shorter than the pre-surgical phase. Treatment ends with retainers.

Total treatment time including all phases is typically 2.5–4 years. This is a significant commitment. Patients who begin orthognathic treatment should understand the full timeline before starting.

## NHS vs private orthognathic surgery

|  | NHS | Private |
| --- | --- | --- |
| **Eligibility** | Significant functional impairment required — aesthetic cases alone may not be funded | No restriction — available to any suitable patient |
| **Cost to patient** | £0 for surgery; orthodontic Band 3 charge £332.10 | £15,000–£35,000+ (orthodontics + surgery combined) |
| **Waiting time** | Often 2–5+ years from referral to surgery date | Can begin within weeks of assessment |
| **Surgeon choice** | Assigned to NHS trust team | Choose your surgeon and hospital |
| **Orthodontic provider** | NHS orthodontist — metal braces only | Private specialist — any appliance type including lingual |
| **Hospital** | NHS hospital trust | Private hospital |

NHS funding for orthognathic surgery is assessed against clinical criteria — the case must demonstrate functional impairment, not just aesthetic improvement. Purely cosmetic jaw surgery is not funded by the NHS. In practice, significant skeletal discrepancies almost always have some functional component, but patients should be aware that NHS funding is not guaranteed and varies by ICB.

### Frequently asked questions

Will the NHS fund my jaw surgery?

NHS funding for orthognathic surgery requires that the case demonstrates significant functional impairment — difficulty chewing, swallowing, breathing, or speaking — not just aesthetic concerns. In practice, significant skeletal discrepancies almost always have functional components. Referral is typically from your orthodontist to an NHS oral and maxillofacial surgery department. Funding approval varies by Integrated Care Board. Cases are assessed against national clinical guidelines. Your orthodontist and oral surgeon will advise on NHS eligibility for your specific case.

What is the recovery from jaw surgery like?

The first week after jaw surgery involves significant swelling, bruising, discomfort, and fatigue. Eating is restricted to liquids and very soft foods for 6 weeks. Speech is affected initially as swelling restricts jaw movement. Most patients can return to office work within 2–3 weeks and feel broadly well within 4–6 weeks, though swelling continues to reduce for several months. Full bone healing takes 3–6 months, during which the post-surgical orthodontics are completed.

Is jaw surgery painful?

Pain is usually well-managed with prescription pain relief during the hospital stay and the first week at home. Most patients describe the initial recovery as uncomfortable rather than severely painful — the main difficulties are swelling, restricted diet, and fatigue rather than acute pain. The surgical cuts are made inside the mouth, so there are no external scars. Numbness (rather than pain) of the chin, lower lip, or upper teeth is common during healing and usually resolves over months.

Can braces alone fix my jaw issue, or do I really need surgery?

Braces can camouflage mild skeletal discrepancies by tipping teeth to compensate — for example, tipping lower front teeth forward slightly to reduce the appearance of a mild underbite. This 'dental compensation' works for mild cases but has limits. If the skeletal discrepancy is significant (more than 4–5 mm of jaw mismatch), orthodontic camouflage produces a compromised result — teeth end up at poor angles, and bite function is not ideal. A joint assessment with both an orthodontist and oral surgeon is needed to determine whether camouflage or surgery is more appropriate for your case.

At what age can I have jaw surgery?

Orthognathic surgery must wait until jaw growth is complete — otherwise the jaw could continue to grow after surgery, undoing the correction. Growth completion is typically 17–18 for females and 18–21 for males, though this varies. Skeletal maturity is assessed using X-rays (hand/wrist or cervical vertebrae staging). In practice, most patients undergoing orthognathic surgery in the UK are 18–30, though it can be performed at any age once growth has stopped.

How long will I be off work or school after jaw surgery?

Most people take around two to four weeks away, though it varies with the procedure and the job. The first week is the most restrictive, with significant swelling, a liquid or very soft diet and limited energy. Swelling reduces markedly over the second and third weeks, and by three to four weeks most people can manage desk-based work or school with adjustments, particularly around eating. Physically demanding work and contact sport are usually excluded for considerably longer, often two to three months. Surgeons give a personalised estimate, and it is worth arranging flexibility in advance.

## Unsure if you need jaw surgery?

An online assessment can give you a preliminary view on whether your jaw relationship is within orthodontic correction range or may need a surgical referral.
