What is double jaw surgery?
Updated: September 24, 2024Double jaw surgery, also known as bimaxillary osteotomy, is a complex oral and maxillofacial surgical procedure aimed at correcting severe jaw deformities and alignment issues. This surgery involves repositioning both the upper (maxilla) and lower (mandible) jaws to enhance facial aesthetics, improve function, and sometimes address medical issues such as obstructive sleep apnea.
Indications for Double Jaw Surgery
Double jaw surgery is typically recommended for individuals who suffer from:
- Severe malocclusion (misalignment of the teeth)
- Jaw deformities that result in an asymmetrical appearance
- Speech difficulties
- Chronic jaw pain or temporomandibular joint (TMJ) disorders
- Obstructive Sleep Apnea (OSA)
Pre-Surgical Evaluation
Before undergoing double jaw surgery, a comprehensive evaluation is essential. This typically includes:
Diagnostic Imaging
Advanced imaging techniques such as X-rays, CT scans, and 3D imaging are used to assess the jaw structure and plan the surgery meticulously.
Orthodontic Assessment
Orthodontic treatment often precedes the surgery to align the teeth properly, making it easier to achieve the desired result.
Medical History and Physical Examination
A thorough review of the patient’s medical history and a physical examination are conducted to ensure they are fit for surgery.
Procedure Overview
The double jaw surgery is performed under general anesthesia and can take several hours. The process can be broken down into several key steps:
Incisions
Incisions are made inside the mouth to avoid visible scarring. In some cases, small incisions might be made externally.
Repositioning the Jaws
The surgeon carefully cuts the bones of the upper and lower jaws, rearranges them to the desired position, and secures them with plates and screws.
Fixation
Titanium plates and screws are commonly used to fixate the bones in their new positions. These materials are biocompatible and rarely cause issues.
Post-Surgical Recovery
Recovery from double jaw surgery can be extensive and requires careful attention to ensure proper healing.
Initial Healing Phase
The first few weeks post-surgery are critical. Patients often experience swelling, bruising, and discomfort. A liquid or soft diet is usually recommended.
Long-Term Recovery
Complete recovery can take several months. Regular follow-up appointments are necessary to monitor healing and make any necessary adjustments.
Potential Risks and Complications
As with any major surgery, double jaw surgery carries certain risks:
- Infection
- Nerve damage resulting in numbness
- Relapse of the jaw position
- Problems with bite alignment
- Complications related to anesthesia
Benefits of Double Jaw Surgery
Improved Functionality
Patients often experience significant improvements in chewing, speaking, and breathing.
Enhanced Aesthetics
The procedure can dramatically enhance facial symmetry and overall appearance.
Patient Stories and Testimonials
Reading about others' experiences can provide valuable insights and set realistic expectations. Many patients report life-changing results, improved self-esteem, and better quality of life post-surgery.
Advanced Techniques and Innovations
Virtual Surgical Planning (VSP)
This advanced technique uses 3D imaging and computer simulations to plan the surgery with high precision, reducing the risk of complications and improving outcomes.
Minimally Invasive Options
Some surgeons are exploring less invasive techniques to achieve similar results with reduced recovery times and fewer complications.
Bioabsorbable Fixation Materials
Innovations in fixation materials, such as bioabsorbable plates and screws, are being researched to minimize long-term complications associated with traditional titanium hardware.
By understanding the intricacies of double jaw surgery, from the initial evaluation to the advanced techniques being developed, one can appreciate the profound impact this procedure can have on those requiring it.

Photorefractive keratectomy (PRK) is a type of refractive eye surgery aimed at correcting vision problems like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It is one of the earliest laser vision correction procedures, first approved by the FDA in 1995. The primary goal of PRK surgery is to reshape the cornea, thereby improving the eye's ability to focus light accurately on the retina.

Knee replacement surgery, also known as knee arthroplasty, is a common procedure aimed at relieving pain and restoring function in severely diseased knee joints. It is typically recommended for individuals with end-stage arthritis or significant trauma to the knee. Understanding the duration of knee replacement surgery involves considering several factors, including the type of surgery, the complexity of the case, and the patient's overall health.
