Orthognathic Surgery with Iliac Bone Grafting

Orthognathic surgery is performed to correct deformities in the jaw and facial region. In some cases, it may be necessary to take bone from another part of the body to strengthen the jawbone and replace missing bone tissue. This bone source is usually taken from the upper part of the hip bone, known as the iliac crest.

An iliac bone graft is a bone tissue taken from the patient’s own body. This bone is added to the missing area in the jaw to create a stronger and more natural structure. Since it is taken from the patient’s own body, the likelihood of rejection is very low.

Jaw underdevelopment or asymmetry: Provides bone support when the upper or lower jaw is too small or positioned incorrectly.
Bone loss due to missing teeth: Tooth loss can lead to bone resorption, making implant placement difficult.
Cleft lip and palate: Used to fill the missing bone in congenital conditions.
Bone loss due to trauma or cyst removal: Helps restore the jawbone after injuries or diseases.

This procedure is performed under general anesthesia while the patient is fully asleep.

1. A small incision is made: A surgical incision is made in the upper part of the hip bone.
2. The necessary amount of bone is removed: Enough bone tissue is taken to be used in the jaw.
3. The area is closed: After the bone is harvested, the area is carefully closed to ensure proper healing.
4. The bone is placed in the jaw: The harvested bone is placed and secured in the jawbone.

✅ Advantages:

• Since it is taken from the patient’s own body, there is no risk of rejection.
• Supports new bone formation.
• Provides a long-term and reliable solution.

⚠️ Disadvantages:

• The area where the bone is taken may have temporary pain and sensitivity.
• Requires an additional surgical site, leading to a longer recovery period.

Most patients can return to daily activities within 1-2 weeks. Mild pain and swelling may occur at the graft site, but these symptoms gradually subside.

To speed up the healing process:

• Stay hydrated and maintain a balanced diet.
• Avoid strenuous physical activities.
• Take prescribed medications as directed.
• Maintain good hygiene to reduce the risk of infection.

Iliac bone grafting is a reliable method to strengthen the jawbone and improve both aesthetics and function. Being well-informed about the pre- and post-operative process can help ensure a successful outcome.
