This helps in assessing the actual deformity Bony and soft tissue. CT scan, Virtual surgical planning, Splints and 3D models — CT scans of the facial bones are taken and then surgical planning is carried out online with special software which helps the surgeon in planning the actual cuts on the bone, moving the bones to the right position and then fixing the bone with plates and screws.
Surgical splints and 3D models are also prepared using virtual surgical planning. Speech assessment — Moving the jawbones can have an impact on speech and hence a speech assessment before surgery and possible speech therapy after surgery will help in optimizing the result.
Routine blood tests before anaesthesia. Orthodontics first approach — This will involve the application of braces and orthodontic dental treatment for a period of 6 months to 1 year followed by surgery. During the orthodontic treatment period, all the compensations of the teeth that are present due to the malocclusion are removed Decompensation.
During this period, you may notice that the deformity of the teeth is getting worsened, but in reality, it is just going back to where it is supposed to be. And once the surgery is done, the alignment of teeth will be normal.
Some amount of orthodontic treatment is sometimes required even after surgery. Surgery first approach — Here the jaw surgery is done first. It is then followed by orthodontic treatment for 6 months to 1 year.
Both approaches are available at Sakra World Hospital. Lefort I osteotomy — In this operation, cuts are made in the upper jaw maxilla and the bone is moved forwards, backwards, upwards or downwards depending upon the deformity and then fixed with titanium plates and screws in the new position. Bilateral sagittal split osteotomy of the mandible BSSO — In this operation, cuts are made in the lower jaw mandible and the bone is moved forwards, backwards, sideways or rotated upwards depending on the deformity and then fixed with titanium plates and screws in the new position.
Double jaw surgery — It is a combination of the above procedures which involves surgery on both maxilla and mandible. Genioplasty — In this operation, cuts are made in the chin central region of the lower jaw and the bone moved forwards, backwards, upwards or downwards depending upon the deformity. Investigations and planning — Takes days for surgical planning and preparation of splints and models. One night ICU stay which might also involve blood transfusions.
ICU stay is for monitoring of the airway and breathing issues. Orthognathic surgery is very safe with the best surgical and anaesthetic practices.
In spite of all safety measures, there might be a few complications which need to be understood by the patient. Infection — Very rare to have infections due to titanium plates and screws. In case there is an event like that, the plates and screws can be removed easily. Swelling and bruising — The patient will have a lot of swelling and bruising in the first 48 hours. Numbness and paraesthesia of lips — Some amount of numbness and altered sensation on the lips are present due to impact on the nerves due to surgery.
This is usually temporary. In a worst-case scenario, it can take years for the sensations to come back. Loss of tooth — Due to loss of blood supply to the teeth. In such cases, dental rehabilitation is required. This is also a very rare complication. Jaw surgery or.. Read more. What is Craniofacial.. Mohammed Saeed.. What is Rhinoplasty? What is Liposuction?

Obstetrics and gynaecology. In surgery to remedy a small chin genioplasty , the front part of the lower jaw is divided and that piece is moved forward and secured with plates and screws.
A genioplasty can correct a small chin deficient chin. A small chin often accompanies a severely receded lower jaw. Typically, surgeons can alter the jaw and restructure the chin during the same surgery. The surgeon cuts a piece of the chin bone on the front of the jaw, moves it forward, and secures it in a new position with plates and screws.
Initial jaw healing typically takes about six weeks after surgery, but complete healing can take up to 12 weeks. After initial jaw healing — at about six weeks — your orthodontist finishes aligning your teeth with braces. The entire orthodontic process, including surgery and braces, may take several years. Once the braces are removed, retainers to hold tooth position may be used. Explore Mayo Clinic studies of tests and procedures to help prevent, detect, treat or manage conditions.

Depending on your individual requirements, the first stage may involve an orthodontist levelling and aligning your teeth with braces. This alignment process can take between twelve to eighteen months. However, this phase is not required for every patient and will be decided upon after your initial consultation.
The results of this planning will allow for the creation of custom-made surgical guides and templates to assist in making sure that surgery proceeds according to your needs. These custom guides can reduce the operating time and therefore reduce the time you are under anaesthetic , operative complications are minimised nerves and vital structures are preserved , and surgical accuracy is optimised.
An operation date is then scheduled to surgically reposition your upper jaw, lower jaw, chin or nose or combinations of these to achieve an ideal alignment between your teeth and jawbones your chin, nose and lips.
Jaw surgery is performed in hospital, where you will be an in-patient for two to three days. The procedure will be performed under full general anaesthetic you are asleep and takes approximately two to four hours to complete. Most procedures involve osteotomy, which are incisions that are made inside the mouth to enable the cutting of the bones of the face.
Because these areas are concealed within either the mouth, nose or facial skin creases, the chance of visible scarring is significantly reduced. The bones that have been cut from the osteotomised jaw can then be moved to their planned new positions and held in place using mini-plates and screws. The plates and screws allow the bone to heal back to its original strength. They are usually not visible, not painful and not needed beyond ten to twelve weeks post-surgery.
After orthognathic surgery, there will often be a need for further orthodontic fine-tuning and adjustment of the teeth for a period of three to six months. This will ensure the upper and lower teeth mesh together correctly and allow a patient to bite in the correct alignment.
If you started with orthodontic treatment Stage 1 , you will typically need to wear braces for three to six months after surgery. Once your braces have been removed, your orthodontist may recommend using a retainer to maintain the position of your teeth and prevent relapse. Once the orthognathic surgery is completed, most patients will stay in hospital for two to four days to ensure they have access to effective pain relief. After being released from hospital, the pain will be well controlled with scripted tablet medication, which may be needed for an additional seven to ten days after surgery.
During the first two weeks, facial swelling reaches its peak and begins to settle during the third week after surgery. Once four weeks have elapsed, most patients are looking more normal, feeling more comfortable and are able to eat a wider range of foods.
The initial healing of jawbones usually takes six to eight weeks, although the complete healing process can take up to 12 weeks. As with any major surgery, your specialist surgeon will detail a post-surgery recovery plan that includes pain relief medications, a suggested range of foods to eat, oral hygiene tips and home care advice. A suggested timetable for a return to school or work would also be discussed.
After undergoing jaw surgery, wound healing and your recovery will require extra energy and good nutrition. Your ability to eat anything will also be reduced because chewing will be uncomfortable, and your ability to open your jaw will be limited by facial swelling. However, you can improve your chances of an easier and quicker recovery if you:.
Following corrective jaw surgery, your body will require sufficient nutrition and vitamins for proper bone and tissue healing, so consuming a diet of soft, easy-to-eat semi-fluid consistency foods is essential.
High protein, calorie-rich foods are ideal and modified foods can be slurped from a spoon or sucked through a straw.
