Medical Guide

Skeletal Jaw Repositioning (Orthognathic)

Orthognathic surgery is indicated when there is a severe mismatch between the size or position of the upper jaw (maxilla) and the lower jaw (mandible). These skeletal discrepancies cannot be corrected with dental braces alone, as moving teeth beyond their bony support leads to instability. Realignment of the underlying bones is necessary to establish functional biting contacts and facial balance.

1. Double Jaw Surgery (Le Fort I & BSSO)

Most complex corrections utilize a double jaw approach (bimaxillary osteotomy). A Le Fort I osteotomy mobilizes the maxilla to correct vertical growth excess (gummy smile) or under-development. Concurrently, a Bilateral Sagittal Split Osteotomy (BSSO) is executed on the mandible, sliding it forward or backward to resolve class II (overbite) or class III (underbite) malocclusion. Rigid fixation with miniplates locks the segments into their planned bite.

2. Genioplasty & Chin Advancement

A genioplasty involves cutting and repositioning the chin segment of the lower jaw. Unlike chin implants, which can cause bone erosion over time, an advancement genioplasty moves the patient's own bone forward, sliding the muscle attachments along with it. This provides a natural profile projection, refines the neck-jaw angle, and physically pulls the base of the tongue forward to prevent airway obstruction.

3. Resolution of Obstructive Sleep Apnea (OSA)

Patients with severe receding chins (retrognathia) frequently suffer from sleep apnea, as their tongue falls backward during sleep, closing off the throat. By executing a Maxillomandibular Advancement (MMA), both jaws are brought forward by 10-12mm. This expands the diameter of the upper respiratory airway, offering a high-rate surgical cure that eliminates the need for CPAP machines.

Orthognathic Surgery Q&A

Scientific explanations covering jaw correction, timelines, and surgical access.

Naturally, teeth try to tilt or compensate to make contact when jaws are misaligned (dental compensation). Before jaw surgery can be safely executed, these compensations must be reversed (decompensation) using dental braces. This ensures that when the surgeon physically moves the jawbones into their correct skeletal positions during surgery, the upper and lower teeth will meet perfectly.
No. Corrective jaw surgeries (including Le Fort osteotomies, BSSO, and genioplasties) are executed entirely through intraoral incisions inside the mouth. There are no cuts made on the skin of the face. The surgical titanium screws and plates are also secured beneath the gum line, resulting in completely scar-free outer facial skin.
In patients with retrognathic (receding) jaws, the narrow bony structure pushes the base of the tongue and throat muscles backward, constricting the airway during sleep. By performing a Maxillomandibular Advancement (MMA), the surgeon moves the upper and lower jawbone forward by 10-12mm. This physically expands the soft tissue envelope and airway volume, treating obstructive sleep apnea at its structural root.
Patients typically remain in the hospital for 1 to 2 days after double jaw surgery. Facial swelling peaks at 48-72 hours and resolves by 70% within 2 weeks. Most patients can return to non-strenuous desk work or school by week 3. Complete bone healing (bony union) takes 8 weeks, during which a soft diet must be strictly maintained to protect the microplates.
