What is a bilateral sagittal split osteotomy?
A bilateral sagittal split osteotomy is a type of jaw surgery in which the lower jaw (mandible) is split bilaterally (moved forward or backward) to straighten it to a more balanced and functional position. It is performed to correct types of malocclusion, a misalignment of teeth.
How long does mandibular osteotomy take?
During surgery Most surgeries take 2 to 5 hours, but the exact length of time depends on the specific procedure being performed. During jaw surgery, most of the incisions are made inside your mouth, although in some cases very small incisions will be made on the outside.
How long is lower jaw surgery recovery?
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.
What is bilateral jaw surgery?
A Bilateral Sagittal Split Osteotomy (or BSSO) is a type of jaw surgery where the lower jaw is separated from the face and repositioned. This repositioning is also called orthognathic surgery. This particular virtual patient has a protruding jaw which will be set back using a BSSO.
Is jaw surgery painful?
Jaw surgery is usually performed after the growth stops, which is around ages 14 to 16 years for females and 17 to 21 years for males. The surgery is performed under general anesthesia, so there is no pain during surgery. Patients usually experience pain after the anesthesia wears off, which can last for a few days.
Does jaw surgery leave scars?
SCARS: Corrective jaw surgery is generally performed entirely inside the mouth; therefore, no external scars are produced. Occasionally, a very small (less that ½ inch) neck incision is required for placement of jaw screws to stabilize bone fragments.
How much weight do you lose after jaw surgery?
Following your surgery and throughout the post-operative recovery period, especially if your jaw is wired shut, you could lose as much as 10 percent of your body weight.
Does jaw surgery Change your eyes?
RESULTS: After bimaxillary orthognathic surgery, eye canting decreased from 2.6 to 1.5 degree, eye and lip lines came closer to parallel. Degree of head tilting also decreased from 3.4 to 1.3 degree. Although not statistically significant, eye opening area became wider after surgery.
What kind of surgery is bilateral Sagittal Split Osteotomy?
A Bilateral Sagittal Split Osteotomy (or BSSO) is a type of jaw surgery where the lower jaw is separated from the face and repositioned. This repositioning is also called orthognathic surgery. The virtual patient in the CIVA demonstration has a protruding jaw which will be set back using a BSSO.
Can a bilateral sagittal split cause asymmetry?
Horizontal mandibular excess, deficiency, and/or asymmetry are indications for a bilateral sagittal split. It is the most widely used treatment for mandibular advancement and can also be used for a mild to moderate mandibular setback.
Which is better for skeletal stability miniplate or BSSO?
BSSO for mandibular advancement is a good treatment option for skeletal Class II, but seems less stable than BSSO setback in the short and long terms. Bicortical screws of titanium, stainless steel, or bioresorbable material show little difference regarding skeletal stability compared with miniplate …
How are bone separators used to split the jaw?
Through the cut bone edges, bone separators called “osteotomes” are used to split the jaw. Once the bones are separated on both sides, the lower jaw can be moved into its new position. If the lower jaw is set back, a small strip of bone may have to be removed.
