Jaw surgery corrects misalignment, breathing problems, and structural abnormalities of the upper and lower jaw. Jeffersontown Oral Surgery provides surgical correction of bite problems, sleep apnea, and trauma reconstruction using advanced imaging and surgical techniques. Treatment planning begins with 3D imaging and consultation to determine whether surgery alone or combined orthodontic-surgical treatment is appropriate.

Types of Jaw Surgery
Orthognathic surgery (corrective jaw surgery) addresses skeletal discrepancies that cannot be resolved by orthodontics alone. The most common procedures are maxillary advancement (moving the upper jaw forward), mandibular advancement (moving the lower jaw forward), and bimaxillary surgery (moving both jaws). Genioplasty reshapes the chin to improve facial balance and bite function. Distraction osteogenesis gradually lengthens the jaw bone over weeks, allowing soft tissue to expand naturally. Sleep apnea surgery widens the airway by advancing the jaw or removing obstructing tissue. Trauma reconstruction repairs fractures and restores jaw function after accidents or injury.
Indications for Jaw Surgery
Jaw surgery is indicated when the skeletal relationship between upper and lower jaw creates functional or aesthetic problems that orthodontics cannot fully resolve. Common reasons include severe overbite or underbite, open bite (front teeth do not meet), crossbite affecting one or both sides, and asymmetry visible in profile or frontal view. Obstructive sleep apnea unresponsive to CPAP or oral appliances often improves significantly with jaw advancement. Difficulty chewing, speaking, or swallowing due to jaw position may warrant surgical correction. Trauma, tumor removal, or congenital conditions (cleft palate, hemifacial microsomia) frequently require jaw reconstruction.
Surgical Planning and Timeline
Jaw surgery requires a team approach involving the oral surgeon, orthodontist, and sometimes a sleep medicine physician. Pre-surgical orthodontics typically takes 12–24 months to align teeth and prepare the bite for surgery. During this phase, the orthodontist and surgeon coordinate to ensure teeth are positioned optimally for the planned jaw movements. 3D cone-beam CT imaging guides surgical planning and allows virtual surgical simulation. The surgical procedure itself lasts 1–4 hours depending on complexity. Most patients remain hospitalized overnight or are discharged the same day. Post-operative swelling peaks at 48–72 hours and gradually resolves over 4–6 weeks. Full bone healing takes 8–12 weeks; return to normal diet and activity progresses gradually over 3–6 months.
Recovery and Post-Operative Care
Immediately after surgery, the jaw is typically immobilized with elastics or plates to stabilize the new position. Pain is managed with prescription analgesics for the first 1–2 weeks. Swelling is minimized with ice application, head elevation, and compression. A soft or liquid diet is necessary for 4–6 weeks; progression to normal foods depends on healing and comfort. Oral hygiene is critical; patients rinse gently with salt water and use prescribed antimicrobial rinse. Numbness or tingling of the lower lip or chin is common and usually resolves within weeks to months as nerve sensation returns. Physical therapy or jaw exercises may be recommended to restore normal function. Most patients return to light activity within 2–3 weeks and full activity within 6–8 weeks.
Risks and Complications
Temporary swelling, bruising, and discomfort are expected and resolve with time. Nerve injury affecting sensation in the lower lip, chin, or teeth occurs in a small percentage of cases; most recover fully within 6–12 months. Infection is rare when antibiotics are used and oral hygiene is maintained. Relapse (partial return to the original jaw position) can occur if post-operative orthodontics is not completed or if growth continues. Temporomandibular joint (TMJ) problems are uncommon but may develop if the new bite position stresses the joint. Bleeding, blood clots, and anesthesia complications are managed according to standard surgical protocols. Open communication with your surgeon about pre-existing conditions (sleep apnea, TMJ disorder, bleeding disorders) reduces risk.
What You Can Expect at Jeffersontown Oral Surgery
Jeffersontown Oral Surgery evaluates each patient with detailed clinical examination, 3D imaging, and bite analysis to determine whether surgery is necessary and what type of procedure will achieve the best functional and aesthetic outcome. The surgical team coordinates closely with your orthodontist to ensure pre-operative tooth positioning and post-operative retention are optimized. Patients receive detailed pre-operative instructions, anesthesia options, and realistic timelines for recovery and return to normal function.
Post-operative follow-up includes regular check-ins to monitor healing, manage swelling and pain, and ensure proper jaw positioning. The team provides clear guidance on diet progression, oral care, activity restrictions, and when to contact the office with concerns. Patients are supported throughout the entire treatment journey, from initial consultation through final orthodontic refinement.
Frequently Asked Questions
How long does jaw surgery take?
Most jaw surgery procedures take 1–4 hours depending on the complexity and number of jaw segments being moved. Simple single-jaw procedures are typically shorter; bimaxillary surgery or reconstruction cases may take longer. Your surgeon will provide an estimated duration during pre-operative consultation.
Will I need braces before and after surgery?
Pre-operative orthodontics is almost always necessary to align teeth and prepare the bite for surgery; this typically takes 12–24 months. Post-operative orthodontics (usually 6–12 months) refines the bite and ensures long-term stability. Your orthodontist and surgeon coordinate the timing and goals of each phase.
How much pain should I expect after surgery?
Pain is typically moderate to severe for the first 3–5 days and is managed with prescription pain medication. By 1–2 weeks, most patients transition to over-the-counter analgesics. Pain should steadily decrease; if it worsens after initial improvement, contact your surgeon to rule out infection or other complications.
When can I return to work or school?
Most patients return to desk work or light activity within 2–3 weeks. Return to strenuous exercise, contact sports, or physically demanding jobs takes 6–8 weeks to allow bone healing and reduce swelling. Your surgeon will provide specific clearance based on your job demands and healing progress.
What type of anesthesia is used?
Jaw surgery is performed under general anesthesia with endotracheal intubation (breathing tube) to protect the airway and allow the surgeon full access to the jaw. Local anesthesia with epinephrine is also infiltrated to reduce bleeding and post-operative pain. Your anesthesiologist will discuss your medical history and anesthesia options during pre-operative evaluation.
Can jaw surgery fix sleep apnea?
Jaw advancement surgery (mandibular or bimaxillary advancement) can significantly improve or resolve obstructive sleep apnea by enlarging the airway space. Success rates are high when the apnea is primarily positional or skeletal in origin. Your sleep medicine physician and surgeon will determine whether surgery is appropriate for your specific apnea severity and anatomy.
