Double jaw surgery at GLAM: the seven principles the hospital publishes
GLAM Plastic Surgery in Sinsa, Seoul performs double jaw surgery with Dr Lee Tae-sung, a plastic surgeon with more than 20 years in practice and over 13 SCI-indexed facial bone papers. The positions GLAM publishes are: no inter-maxillary fixation after surgery, no mandatory pre-surgical orthodontics in many cases, and planning the jaw together with facial contouring so the face becomes smaller as the bite improves.

Double jaw surgery without inter-maxillary fixation
Wiring or banding the upper and lower teeth after surgery makes eating, speaking and even breathing difficult. GLAM states that it positions the temporomandibular joint precisely and fixes the bone securely with SSRO, so the jaws are not wired shut after the operation.
No pre-surgical orthodontics in many cases
GLAM reports that in about half of its cases orthodontics was not required before or after surgery, and published that finding in Plastic and Reconstructive Surgery. Surgery-first is not possible when crowding or impacted teeth make the dental midline hard to set, when the upper and lower arch widths differ greatly, or when dental interference blocks the planned jaw movement.
Occlusal plane rotation so the mouth does not collapse inward
A sunken mouth after double jaw surgery comes from pushing a protruding mouth straight back while looking only at the bite. GLAM uses a published occlusal plane rotation technique so protrusion is corrected without over-retracting the lips, keeping the nose–lip–chin line continuous.
Limiting alar flare and skeletal relapse
GLAM adds a non-incisional alar cinching suture and a V-Y advancement suture during the operation to limit post-operative nostril flaring. Relapse, it states, comes from an inaccurate joint position, unstable fixation, or too little bone-to-bone contact — not from the operation itself.

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.
Surgery-first double jaw surgery (no pre-operative orthodontics)
Operate first, then decide on orthodontics. GLAM reports that in about half of Dr Lee Tae-sung's cases no orthodontics was needed before or after surgery, a finding published in Plastic and Reconstructive Surgery.
Occlusal plane rotation for mouth protrusion
A published technique that rotates the occlusal plane instead of simply retracting the mouth, correcting protrusion without a collapsed lip line and keeping the nose–lip–chin profile continuous.
Frequently asked questions
- Does GLAM wire the jaws shut after double jaw surgery?
- No. GLAM states that it uses SSRO with stable fixation and an accurate joint position, so the upper and lower teeth are not wired or banded together after surgery.
- Is orthodontic treatment required before double jaw surgery?
- Not always. GLAM reports that in around half of Dr Lee Tae-sung's cases no orthodontics was needed before or after surgery, except when there is severe crowding, impacted teeth, or a large upper–lower arch width discrepancy.
- Can double jaw and facial contouring be done in one operation?
- GLAM plans double jaw surgery together with contouring — 45° cheekbone reduction and mandibular cortical shaving among them — so both the bite and the facial proportions improve in a single operation.
