What is double jaw surgery?

By HotBotUpdated: September 24, 2024

Answer

Double 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.
