Orthognathic surgery

Procedure Outcomes

- Short-term effects: Within a few weeks after surgery, facial swelling gradually subsides, and patients can initially observe changes in jawbone positioning. Typically, within 1 to 2 weeks, pain and swelling significantly alleviate, and wounds begin to heal.

- Long-term effects: Over time, usually within 3 to 6 months post-surgery, the bones gradually heal and stabilize. The facial contour becomes more natural and aesthetically pleasing, occlusion improves markedly, and chewing and speech functions return to normal.

The following groups are suitable for orthognathic surgery:

• Individuals with severe dentofacial deformities, such as underbites, protruding teeth, or facial asymmetry, who cannot be treated effectively with orthodontics alone.
• People experiencing functional impairments in chewing, swallowing, or breathing due to abnormal jaw development.
• Individuals with high expectations for facial appearance whose dentofacial deformities have negatively affected their psychological well-being and social interactions.

Select Equipment

Commonly used equipment in orthognathic surgery includes:

CT Scanning Equipment: High-quality CT devices provide clear and accurate 3D images of the jawbone, enabling surgeons to comprehensively understand the morphology, structure, and pathology of the patient's jaw. This information serves as a precise basis for developing surgical plans. It is recommended to select CT equipment with high precision and low radiation exposure.

Surgical Navigation System: This system enables real-time tracking of the position and orientation of surgical instruments during the procedure, enhancing the precision and safety of the surgery. Choose a surgical navigation system with excellent stability and accuracy.

Price

The cost of orthognathic surgery varies due to multiple factors, typically ranging from 30,000 to 100,000 Korean won (approximately 22 to 74 USD). Factors influencing the price include:

Complexity of surgery: The more severe the deformity, the higher the surgical difficulty and cost.

Regional differences: Medical expenses in major cities are generally higher than in second- or third-tier cities.

Hospital tier and surgeon experience: Renowned tertiary hospitals and highly experienced surgeons tend to charge higher fees.

Expected Outcomes

Patients should maintain realistic expectations. Although orthognathic surgery can significantly improve facial appearance and occlusal function, it cannot achieve an idealized outcome. Surgical results are influenced by multiple factors, including the patient's underlying skeletal structure, the rationality of the surgical plan, and postoperative recovery. Before the procedure, patients should communicate thoroughly with their surgeon to understand the potential results.

Combined Therapy

Orthognathic surgery is often performed in conjunction with orthodontic treatment. Typically, pre-surgical orthodontics is conducted first, using braces to adjust tooth position and alignment, thereby creating favorable conditions for the surgery. Post-surgical orthodontic treatment is also required for a period to consolidate surgical outcomes and fine-tune occlusal relationships. Additionally, for patients with soft tissue issues of the face, combined facial plastic procedures such as fat grafting or Botox injections may be necessary to achieve optimal overall facial aesthetics.

Side Effects and Complications

- Bleeding and Hematoma: Bleeding may occur during surgery, and hematoma formation is possible post-operatively. These are generally managed through compression, drainage, and other appropriate methods.

- Infection: The oral cavity is a bacterial environment, posing a risk of post-operative infection. Patients must strictly follow medical instructions for oral hygiene and may require antibiotics to prevent infection.

- Nerve Damage: Surgery may damage the inferior alveolar nerve, resulting in numbness or abnormal sensation in the lower lip and chin area. In most cases, nerve function gradually recovers within a few months, though a small number of patients may experience permanent sensory deficits.

- Poor Bone Healing: The jawbone may fail to unite or heal slowly during the recovery process, affecting surgical outcomes. This is influenced by factors such as the patient's age, nutritional status, and post-operative care.

Select Instruments

In addition to the CT scanning equipment and surgical navigation systems mentioned earlier, attention should also be paid to the cutting and fixation instruments used during surgery. For micro-oscillating saws, choose products that offer precise cutting and flexible operation; for fixation materials such as titanium plates and screws, select high-quality options with excellent biocompatibility to ensure stable bone fixation and proper healing.

Contraindications for the Procedure

- Systemic diseases: Patients with uncontrolled severe heart disease, hypertension, diabetes, blood disorders, etc., are not suitable for orthognathic surgery.

- Local oral infections: In cases of periodontitis, periapical periodontitis, or other oral infectious diseases, the infection must be treated first, and surgery should be considered only after the inflammation is controlled.

- Psychological disorders: Patients with unrealistic expectations regarding surgical outcomes or those with severe psychological disorders are not suitable for surgery.

Contraindications for the Procedure

Systemic Diseases: Patients with severe heart disease, hypertension, diabetes, hematological disorders, etc., are not suitable for orthognathic surgery unless their condition is effectively controlled.

Local Oral Infections: In cases of periodontitis, periapical periodontitis, or other oral infectious diseases, the infection must be treated first, and surgery should only be considered after the inflammation is controlled.

Psychological Disorders: Patients with unrealistic expectations regarding surgical outcomes or those suffering from severe psychological disorders are not suitable for surgery.

Side Effects

In addition to the aforementioned side effects such as bleeding, infection, and nerve damage, patients may also experience facial swelling, pain, and limited mouth opening after surgery. These side effects typically gradually subside within a certain period after the procedure, though they may cause some discomfort during the recovery phase.

Self-Diagnosis of Symptoms

If you experience the following symptoms, it may indicate a need to consider orthognathic surgery:

- Abnormal teeth occlusion, such as improper alignment of the upper and lower teeth, resulting in conditions like underbite, deep overbite, or open bite.

- Noticeable facial asymmetry, with one side of the jaw being either overdeveloped or underdeveloped.

- Functional issues, including difficulty chewing and pain in the temporomandibular joint.

Select a Treatment Plan

Doctors will develop personalized treatment plans based on the patient's specific condition. When choosing a treatment plan, patients should communicate fully with their doctors to understand the pros and cons, surgical risks, and expected outcomes of different options. At the same time, consider the feasibility of the treatment plan and your own financial capacity, such as the treatment duration and costs.
