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.
What is a 3 piece LeFort 1 osteotomy?
The LeFort I osteotomy is one of the most commonly used procedures to correct midface deformities. It allows for correction in three dimensions including advancement, retrusion, elongation, and shortening.
What is bilateral maxillary osteotomy?
The operation is all carried out from the inside of your mouth so that there are no visible scars on the skin of your face. A cut is made through the gum above your upper teeth to gain access to the jawbone. The upper jaw is then cut with a small saw to allow it to be broken in a controlled manner.
What is the LeFort procedure?
During the LeFort I surgery, the upper jaw (or maxilla) is separated from the rest of the face and repositioned. This repositioning of the bones of the face is also called orthognathic surgery. Once separated, the upper jaw can be moved up, down, forward, backward, tilted, or turned.
What is the goal for a sagittal split osteotomy?
The purpose of these cuts is to separate the jaw in such a way that will create a broad overlap of bone between the cut surfaces. 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.
What is a maxillary osteotomy?
Your doctor may choose: Maxillary osteotomy. This is a surgery performed on the upper jaw to correct open bites or cross bites. The upper jaw and teeth are moved forward so they align with the lower jaw and teeth.
What does a Genioplasty do?
Chin surgery/genioplasty corrects receding chins, chin misalignment or chin excess. If you are concerned with the position, shape or contour of your chin, chin surgery may be a good option for you to consider. Genioplasty is a commonly performed plastic surgery procedure.
What is Bimaxillary osteotomy?
If your procedure involves both jaws, it’s called a double jaw surgery or bimaxillary osteotomy. The goal is to improve the function and appearance of your jaws. Depending on jaw deformities, a surgeon might reposition your upper and lower jaws. They might also change their size by removing pieces of bones.
What is osteotomy of maxilla?
Upper jaw (maxillary osteotomy) & Lower jaw (mandibular osteotomy) Orthognathic surgery is performed to correct a wide range of skeletal and dental anomalies, including the misalignment of the jaws and teeth. In normal jaw alignment, the upper jaw and teeth project slightly further than the lower teeth.
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.
What is a bilateral maxillary Antrostomy?
Maxillary antrostomy is a surgical procedure to enlarge the opening (ostium) of the maxillary sinus. This allows for further surgical intervention within the maxillary sinus cavity as well as improved sinus drainage.
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 is the Sagittal Split performed in BSSO?
When the BSSO technique was introduced by Schuchardt4and Obwegeser5, the sagittal split was performed with a mallet and chisels. Since then, different modifications of the osteotomy design have been proposed.
How should the mandibular segments be stabilised after bilateral Sagittal Split Osteotomy?
Rigid fixation with either bicortical screws or mini-plates is the current standard to stabilise the mandibular segments after bilateral sagittal split osteotomy (BSSO). Both techniques are widely used and the superiority of any one method is still under debate.
Who invented the Sagittal Split Osteotomy?
Trauner and Obwegeser6subsequently further developed and popularized this technique and are currently viewed as the founding fathers of the sagittal split osteotomy. Initially, the BSSO technique consisted of two horizontal bone cuts, approximately 25mm apart in the lingual and buccal cortex of the mandibular ramus.
