During the surgery, we take great care to protect the nerves that run through the jaws, however, immediately after your surgery some areas of your face might feel numb. After surgery on the upper jaw, the numb feeling is (usually) only in the cheeks, upper lip and teeth. After lower jaw surgery, you might have some numbness of the lower lip, chin and teeth, and possibly the tongue.
Nerves can repair themselves if they are just bruised and if the cut ends lie closely can mend on their own. This means that most numbness after orthognathic surgery will return to normal or near to normal over the weeks or months after the operation.
You also have nerves that control the movement of your facial muscles and jaws. These do not run in the areas of the face and jaws that are routinely operated on during orthognathic surgery in UAE and so the movement of the face and lips should not be affected by this surgery.
