Double jaw surgery

Double jaw surgery (two-jaw orthognathic surgery)

The upper and lower jaws are repositioned together to correct both the bite and facial proportion. GLAM plans it alongside facial contouring, uses SSRO without post-operative inter-maxillary fixation, and anaesthesia is handled by its resident anaesthesiologist.

Who it suits

Protruding or receding chin and facial asymmetry
Mouth protrusion that orthodontics alone cannot correct
Long face, open bite or a gummy smile

Technique highlights

No inter-maxillary fixation, so eating and speaking return sooner
Planned with cortical shaving and 45° cheekbone reduction in one operation
Alar cinching and V-Y advancement sutures limit post-operative nostril flare
The director operates from incision to closure; operating-room CCTV is available on request

Surgical steps

CT imaging and analysis of both occlusion and facial proportion
Planning the movement of both jaws and the occlusal plane
Intra-oral osteotomy: Le Fort I above and SSRO below
Plate and screw fixation with the joint position checked
Pre- and post-operative X-rays reviewed with the patient at the first follow-up

Recovery & aftercare

With no wiring, the mouth opens for speech and liquids from the early stage
Post-op LED therapy, Astro Dome, Care7 and Oligio X help reduce swelling
Follow-up X-rays confirm bone position and the nerve canal

Risks & things to consider

Relapse usually follows an inaccurate joint position or unstable fixation
Congenital temporomandibular disorders need additional assessment first
General anaesthesia is required, so health screening and fasting rules apply

Frequently asked questions

Is the jaw wired shut after surgery at GLAM?

No. GLAM states that its SSRO with accurate joint positioning and secure fixation removes the need for inter-maxillary fixation.

Will double jaw surgery leave the mouth sunken?

GLAM attributes a sunken mouth to over-retraction in the horizontal plane, and uses its published occlusal plane rotation technique to correct protrusion without pushing the lips too far back.
