Orthognathic surgery
Orthognatic surgery
Orthognathic surgery / is surgery to
correct conditions of the jaw and face
related to structure, growth, sleep apnea,
TMJ disorders, malocclusion problems
owing to skeletal disharmonies, or other
orthodontic problems that cannot be
easily treated with braces, it is also used
in treatment of congenital conditions like
cleft palate,
INDICATIONS OF SURGERY
A. Congenital craniofacial deformities
(mandible and maxilla)
B. Severe dento skeletal deformities
Craniofacial deformities

orthognathic surgery
Contemporary surgical
techniques
Le Fort I osteotomy
treatment of upper jaw malocclusion and
cleft palate is upper jaw surgery that
involves sectioning and
repositioning the maxilla,
or upper jaw, to correct its
abnormal position.
Rhinoplasty
It refers to a procedure in plastic surgery in
which the structure of the nose is
changed.
Genioplasty
is more commonly known as chin
repositioning. This surgical procedure is
done to correct receding chins,
Procedure The surgery might involve one jaw or the two jaws during
the same procedure. is performed under general anaesthetic and using nasal
tube for intubation Cutting the bone is called osteotomy and in case of
performing the surgery on the two jaws at the same time it is called a bi-maxillary osteotomy (two jaws bone cutting) Sometimes the midface can be mobilised as well by using a Lefort II, or Lefort III osteotomy. These techniques are utilized extensively for children suffering from certain craniofacial abnormalities
The jaws will be wired together (inter-maxillary fixation) using stainless steel wires during the surgery to ensure the correct re-positioning of the bones. This in most cases is released before the patient wakes up
Post operation
After orthognathic surgery, patients are often
required to adhere to an all-liquid diet. After
time, soft food can be introduced, and then
hard food.
Weight loss due to lack of appetite and the
liquid diet is common, but should be avoided
if possible.
Normal recovery time can range from a few
weeks for minor surgery, to up to a year for
more complicated surgery.
Post operation
Doctors will prescribe pain medication and prophylactic antibiotics to the patient. There is often a large amount of swelling around the jaw area, and in some cases bruising. Most of the swelling will disappear in the first few weeks,
The surgeon will see the patient for check-ups frequently, to check on the healing, check for infection, and to make sure nothing has moved
