Our Summary

This research paper introduces a method for creating 3D virtual simulations of a specific kind of facial surgery called orthognathic surgery. This method doesn’t require any special equipment, software, or specific imaging techniques. The process includes new and simplified steps for creating images, building a 3D model of the skull, controlling the position of a specific part of the jaw, and planning out a two-jaw surgery. The researchers who developed this method have used it in roughly 2000 cases between 2015 and 2022, and it’s become popular with surgeons in their area. Early studies suggest that this method is accurate enough for clinical use, but the researchers want to test it with more patients to confirm its effectiveness.

Doctor’s Tip

A helpful tip a doctor might tell a patient about orthognathic surgery is to follow post-operative instructions carefully, including taking prescribed medications, attending follow-up appointments, and maintaining a soft diet to promote proper healing. It is also important to communicate any concerns or changes in symptoms to your healthcare provider promptly.

Suitable For

Orthognathic surgery is typically recommended for patients who have issues with their bite, jaw alignment, facial asymmetry, or breathing problems due to abnormal jaw structure. Common conditions that may warrant orthognathic surgery include:

  1. Severe overbite or underbite
  2. Open bite
  3. Crossbite
  4. Facial asymmetry
  5. Difficulty chewing or biting
  6. Temporomandibular joint (TMJ) disorders
  7. Sleep apnea or other breathing problems

Patients who are experiencing significant functional or aesthetic issues due to their jaw alignment may benefit from orthognathic surgery. It is important for patients to undergo a thorough evaluation by a maxillofacial surgeon and orthodontist to determine if they are good candidates for the procedure.

Timeline

Before Orthognathic Surgery:

  • Patient undergoes initial consultation with orthodontist and oral surgeon to discuss treatment options
  • Orthodontic treatment (braces) may be required to align teeth before surgery
  • Patient undergoes pre-surgical orthodontic planning, including dental impressions and X-rays
  • Virtual simulation of surgery is conducted to plan the exact movements of the jaw
  • Patient undergoes pre-surgical medical evaluation to ensure they are healthy enough for surgery

After Orthognathic Surgery:

  • Surgery is performed to reposition the jaw(s) into the planned position
  • Patient may stay in the hospital for a few days post-surgery for monitoring
  • Patient will experience swelling, bruising, and discomfort in the days and weeks following surgery
  • Follow-up appointments with the surgical team will be scheduled to monitor progress and make any necessary adjustments
  • Patient may require post-surgical orthodontic treatment to align teeth in their new position
  • Full recovery and final results may take several months to a year

Overall, the timeline for orthognathic surgery can vary depending on the individual patient’s needs and the complexity of the case. It is important for patients to work closely with their surgical team to ensure a successful outcome.

What to Ask Your Doctor

Some questions a patient should ask their doctor about orthognathic surgery may include:

  1. What specific jaw or facial issues will this surgery address?
  2. What are the potential risks and complications associated with orthognathic surgery?
  3. What is the expected recovery time and post-operative care plan?
  4. How will this surgery affect my appearance and function of my jaw?
  5. What are the alternatives to orthognathic surgery and why is surgery recommended in my case?
  6. Can you explain the 3D virtual simulation process and how it will be used in planning my surgery?
  7. How many orthognathic surgeries have you performed using this method and what are the success rates?
  8. What type of anesthesia will be used during the surgery and what are the risks associated with it?
  9. Will I need braces before or after the surgery, and if so, for how long?
  10. Can you provide me with before and after photos of previous patients who have undergone orthognathic surgery using this method?
