Orthognathic and Maxillofacial Surgery

Orthognathic surgery, also known as corrective surgery, is undertaken by specialist oral and maxillofacial surgeons to correct the mandible and conditions associated with the mandible by placing the jaw and or the maxilla (cheek) in a new and more natural position. It is usually reserved for conditions that cannot be corrected with braces alone. There is a range of surgeries within orthognathic surgery, from genioplasty to sagittal split osteotomy and Maxillomandibular advancement (Bimaxillar advancement/Bimax).

Why Should I Get Orthognathic Surgery?

Orthognathic and maxillofacial surgery is designed for people with dentofacial deformities. It is estimated that around 1 in 10-20 of the UK population suffer from such deformities and that these deformities are not solved by orthodontic treatment (braces).

Orthognathic surgery can be used to treat misplaced mandibles, be it one’s jaw is too far forward (underbite) or too far back (overbite). Orthognathic surgery can also be used when the deformity is causing secondary effects on the individual, such as sleep apnoea or affecting the temporomandibular joint (TMJ), giving rise to pain. Everyone is assessed individually by our network of clinicians, who will take the time to evaluate before explaining treatment options.

Orthognathic Surgery / Maxillofacial Surgery Procedure Explained

It isn’t easy to outline the procedure fully, as everyone is assessed individually. Most people will be required to wear braces for some time before any surgery to get the teeth into the position needed for correction. Most procedures require you to stay in hospital for a few days and will be performed under general anaesthetic. Most procedures will mean you are swollen with temporary numbness of the nerves around the face, causing some bruising. You may be supplied with a special cooling mask to help reduce the swelling and the pain.

Most orthognathic and maxillofacial procedures will require you to have a soft diet to start with and may need you to continue this for 6 weeks as the bone heals.
