ROSEMONT, Ill., Sept. 16 /PRNewswire/ -- A bone-cutting technique that
drastically reduces the length of adult orthodontic treatment and
biocompatible mini-devices that replace the need for open surgery are among
the innovations that will be presented at a symposium on minimally invasive
orthognathic surgery at the American Association of Oral and Maxillofacial
Surgeons (AAOMS) 87th annual meeting in Boston.

"All of these developments share the goal of taking a more involved
surgical procedure and making it simpler -- transitioning a procedure that was
traditionally done in the hospital under general anesthesia to an outpatient
or office-based procedure using local anesthesia," states symposium moderator
Joseph E. Van Sickels, DDS, division chief of oral and maxillofacial surgery
and director of the oral and maxillofacial residency program at the University
of Kentucky in Lexington.
Orthognathic surgery repositions, widens and/or narrows the upper and/or
lower jaws in order to improve function and appearance. As orthognathic
surgery specialists, oral and maxillofacial surgeons often work with
orthodontists to achieve results braces alone cannot accomplish.
Until recently, orthognathic surgery involved at least an overnight stay
in the hospital. As in virtually every other surgical specialty, the
development of minimally invasive techniques in orthognathic surgery is now
saving patients the discomfort and expense of longer, more elaborate
operations and hospitalizations, Dr. Van Sickels says. Though the techniques
vary, "they are all about reducing patient discomfort and recovery time and
minimizing costs without compromising results," he says.
Orthodontists often refer their patients to oral and maxillofacial
surgeons for an orthognathic procedure known as a maxillary osteotomy,
traditionally performed under general anesthesia in a hospital operating room.
The procedure raises the upper jaw in the back of the mouth in order to close
the bite in front and achieve a more functional and esthetically pleasing jaw
Through the new minimally invasive technique, the oral and maxillofacial
surgeon surgically places titanium miniplates in the cheekbone, where they
function as skeletal anchors that move the molars in the back of the mouth up,
facilitating bite closure. "This combined approach to open bite treatment
appears to be stable and effective," Dr. Sherwood says.
Another technique, known as selective alveolar decortication, can reduce
the length of orthodontic treatment in adult patients by 60 to 70%, according
to Boston OMS Ruben Figueroa, D.M.D., M.S. "Six month treatment times are
common when standard orthodontia and alveolar decortication are combined to
treat moderate and severe malocclusions, including crowding, cross bite and
open bite treated with or without orthognathic surgery," he reports.
A technique first used by orthopedic surgeons known as distraction
osteogenesis now offers OMSs a less invasive method for more effectively
remedying many severe, difficult to treat facial skeletal deformities,
including cleft palate. The OMS makes a gradual, controlled series of small,
surgically created fractures to "stretch" bone in a given direction. By
triggering the body's natural healing process, the technique "tricks" the body
into forming new bone and can even be used to extend bone between specific
Because distraction osteogenesis is done slowly, in small increments, over
several office visits, the technique facilitates the simultaneous generation
of surrounding gum and other soft tissues as the bone gradually lengthens or
widens, Dr. Van Sickels reports.
The American Association of Oral and Maxillofacial Surgeons (AAOMS), the
professional organization representing more than 7,000 oral and maxillofacial
surgeons in the United States, supports its members' ability to practice their
specialty through education, research, and advocacy. AAOMS members comply with
rigorous continuing education requirements and submit to periodic office
examinations, ensuring the public that all office procedures and personnel
meet stringent national standards.
