Know the basics

What is Le Fort 1 osteotomy?

Le Fort 1 osteotomy is an operation to change the position of your upper jaw so your teeth can be aligned. There is a limit to how far your orthodontist can use orthodontics (braces) to move your teeth. Sometimes it is not possible to complete the alignment of your teeth without improving the position of your upper jaw.

Why is Le Fort 1 osteotomy performed?

If your child or you have occlusal variation (a condition that is the teeth and the jaw are not aligned) due to cleft palate, Le Fort 1 osteotomy is an option for treatment.

Your face after surgery may be not as you expected. Changes in the face can happen up to 1 year after surgery. The movement of the face can change your nose or mouth appearance. Facial bones can be broken in an unexpected position. The teeth can be damaged or have problems when you use them. In some rare cases, your skull bone can be broken, causing spinal fluid to flow out of the ear or nose.

The orthodontist sometimes can use orthodontics to align the teeth but it’s not sure that two sets of teeth will always bite fit. In this case, you often have to put on braces permanently at the back of the teeth or wear bands forever to keep the teeth in placed.
