How Orthognathic Surgery Works: Step-by-Step Procedure and Recovery

1. Introduction

1.1 What Is Orthognathic Surgery?

Orthognathic surgery, also known as corrective jaw surgery, is a specialized procedure designed to correct jaw misalignment, improve facial harmony, and enhance chewing, breathing, and speaking functions.

This surgical procedure is recommended for individuals who experience:

Jaw misalignment that cannot be corrected with braces alone.
Overbite, underbite, or crossbite affecting facial aesthetics and oral function.
Breathing issues such as sleep apnea due to airway obstruction.
Facial asymmetry caused by an uneven or recessed jaw.

1.2 Why Is Orthognathic Surgery Performed?

Orthognathic surgery is performed for both functional and cosmetic reasons, including:

Improving the ability to chew and speak properly.
Correcting severe bite problems that lead to excessive tooth wear.
Enhancing facial balance and aesthetics.
Reducing airway obstructions that cause sleep apnea.
Preventing jaw joint (TMJ) disorders and related pain.

This procedure provides long-term benefits and can significantly improve both oral health and quality of life.

2. Benefits of How Orthognathic Surgery Works: Step-by-Step Procedure and Recovery Therapy

2.1 Pre-Surgical Consultation and Planning

Before undergoing orthognathic surgery, a detailed evaluation is necessary. This phase includes:

Comprehensive dental and facial analysis using X-rays, CT scans, and 3D imaging.
Collaboration between an orthodontist and a maxillofacial surgeon to determine the best treatment plan.
Orthodontic treatment (braces) for several months before surgery to align teeth properly.
Customized surgical planning to determine the precise movements needed for jaw correction.

During the consultation, the surgeon will explain the procedure, risks, and expected outcomes to ensure the patient is fully prepared.

2.2 The Surgical Procedure Explained

Orthognathic surgery is performed under general anesthesia and takes 2-6 hours, depending on the complexity.

Types of Orthognathic Surgery:

Maxillary Osteotomy (Upper Jaw Surgery):
- Performed for severe overbite, open bite, or asymmetry.
- The upper jaw is cut, repositioned, and stabilized using plates and screws.
Mandibular Osteotomy (Lower Jaw Surgery):
- Corrects underbite or receding jaw by moving the lower jaw forward or backward.
Bimaxillary Osteotomy (Double Jaw Surgery):
- Involves both upper and lower jaw corrections for severe misalignment.
Genioplasty (Chin Surgery):
- Used to reshape the chin for better facial proportions.

Once the adjustments are made, the jaw is secured with screws and plates, and the incision is closed. The patient is then monitored during the initial recovery phase.

2.3 Immediate Post-Surgery Recovery

Patients wake up with swelling and mild discomfort, which is managed with pain medications.
A liquid or soft-food diet is required initially due to jaw stiffness.
Mild bruising and numbness are common but temporary.

Patients usually stay in the hospital for 1-3 days before being discharged.

3.1 First Week of Recovery

Swelling is at its peak but gradually reduces with cold compress therapy.
Patients are advised to rest with their head elevated to minimize swelling.
A strict soft-food diet is followed to avoid putting stress on the healing jaw.

Medications, including painkillers and antibiotics, are prescribed to prevent infections.

3.2 Diet and Lifestyle Adjustments

Soft and liquid foods such as soups, smoothies, and mashed foods are required for several weeks.
Avoid chewing hard or sticky foods to prevent strain on the jaw.

Patients should stay hydrated and avoid smoking or alcohol, which can delay healing.

3.3 Long-Term Healing and Final Results

After 6-8 weeks, patients can gradually transition back to a normal diet.
Braces are usually removed after full jaw healing (typically 6-12 months post-surgery).
Most patients experience full recovery within 6 months, with final results visible after 1 year.
Follow-up appointments ensure that healing progresses correctly.
