What is orthognathic surgery?
Orthognathic surgery repositions the upper jaw (maxilla), lower jaw (mandible) or both — bimaxillary / double jaw surgery — to correct bite problems, sleep-disordered breathing and skeletal disharmony such as a receded chin, gummy smile or long-face pattern. Because the jaws set the framework of the lower face, the change is both functional and profoundly aesthetic.
3D virtual surgical planning
Every case is planned digitally from CT data: the osteotomies are simulated, the movements measured to the millimetre, and patient-specific cutting guides prepared before the operation. You see the planned change before surgery, and the plan transfers precisely to the operating room. Read more in our double jaw surgery guide.
Aesthetics and function together
Dr. Cömert's practice is unusual in combining orthognathic surgery with aesthetic facial surgery — so the plan considers the nose, chin, cheeks and soft tissues as one composition. Where a small refinement remains after skeletal correction, custom implants or rhinoplasty complete the result. Orthodontic preparation is coordinated with your orthodontist before and after surgery.
Genioplasty (chin surgery)
Genioplasty reshapes the chin at the bone to correct a receding (retrogenic), over-projected or asymmetric chin and to balance the lower face. In a sliding genioplasty, the chin bone is separated with a fine osteotomy and repositioned — forward, backward, up, down or rotated to correct asymmetry — then secured with titanium plates. Because it moves your own bone rather than adding material, the result is stable and completely natural, and it avoids the limitations of a chin implant.
Genioplasty is often combined with double jaw surgery to perfect the profile, or performed on its own when the bite is already correct but the chin needs more projection and a sharper jawline. It is carried out entirely through a small incision inside the mouth, so there is no visible external scar. Dr. Cömert plans every movement in millimetres from 3D CT data, treating the nose, lips, chin and neck as one aesthetic unit — and where extra definition is wanted, a custom chin or jaw implant can complement the result.
Multiple-piece (segmental) Le Fort I surgery
A standard Le Fort I osteotomy repositions the entire upper jaw (maxilla) as a single block. A multiple-piece — or segmental — Le Fort I divides the maxilla into two or three segments during the same operation, giving independent control over the front teeth, the width of the palate and the levels of the dental arch. This makes it possible to widen a narrow upper jaw (transverse expansion), level an uneven bite, close an open bite and refine the smile in ways a one-piece movement cannot.
Multi-piece Le Fort surgery is reserved for more complex cases: significant transverse (width) deficiency, marked asymmetry, or a combined vertical-and-horizontal discrepancy — usually as part of bimaxillary (double jaw) surgery. It relies on precise 3D virtual surgical planning and patient-specific cutting guides, which are central to Dr. Cömert's orthognathic protocol, and it is coordinated closely with your orthodontist so the segments heal into a stable, healthy bite.
Recovery, step by step
- Days 1–2: hospital stay; swelling peaks around day 3.
- Weeks 1–2: home rest; speaking and gentle activity return quickly. Numbness in the lip and chin is normal and fades over weeks to months.
- Weeks 1–6: a staged liquid-to-soft diet protects the healing bone.
- 6–12 months: bone fully consolidates and the final facial balance settles.
