| Mr. Heberling was completing a morning ride on September 10, 2001. He
was just one driveway away from home when his bicycle made contact with
a moving mini-van, sending him face-first into the windshield and then
sliding off the vehicle. "I recall going out bicycling that morning and going through the
typical feelings of how it would be more comfortable lying in bed,"
he says. "But I dont recall the actual collision." Fortunately, he was wearing the Bell Biker helmet that he bought more
than 20 years ago. That spared him from serious brain injury and possibly
saved his life. Still, his injuries were extensive enough that he was
taken by helicopter to The New Jersey Trauma Center at University Hospital.
He had a lacerated liver, a bruised kidney, and three fractured ribs.
Those injuries were treated, and the next day, when he was medically stable,
attention turned to repairing the mans face. Mr. Heberling had one of the most severe types of facial fractures, a
Le Fort III; his upper jaw was broken in two places and his lower jaw
was literally split down the middle. He lost eight front teeth in the
accident, six on top and two on the bottom. As Mr. Heberling was about
to discover, facial reconstruction can be a slow but necessary road to
healing. Facial reconstruction following an accident such as Mr. Heberlings
can be complex. Theres much more than appearance to consider, such
as damage to the jaws and teeth, which can compromise a persons
ability to chew and to speak correctly; soft tissue injuries, and injuries
to the facial nerves or salivary glands. Thats why an oral and maxillofacial
surgeons interdiscipinary training is so valuable. The average person probably associates oral surgery more with removing
wisdom teeth than with treating head and facial injuries. However, oral
and maxillofacial surgeons have a unique blend of dental and surgical
training. After completing dental school, they undergo a four-year hospital-based
residency where more than 30 percent of their training involves trauma
management. Some, such as Dr. Vincent Ziccardi, Mr. Heberlings surgeon,
also earn a medical degree. Facial traumas run the gamut from a fractured cheek bone to "knocked
out" teeth to a badly cut lip. Many are caused by automobile accidents,
sports injuries, assaults, or falls. While not all injuries are of equal
severity, even seemingly minor facial lacerations can warrant medical
attention because of their location near nerves or for cosmetic reasons.
A facial trauma patients immediate medical needs can be taken care
of in an emergency room or sometimes at an oral surgeons office.
But after the initial treatment, additional post-trauma facial reconstruction
may be necessary. "It varies case by case. Some patients might need scar revisions
or dermabrasion," says Dr. Ziccardi. "On another level of reconstruction,
dental rehabilitation is what it takes to make the patient whole." Mr. Heberling fell into the second category. The day after the accident,
Dr. Ziccardi performed open reduction and rigid fixation of the facial
fractures to reposition the cyclists fractured jaws. Because a broken
jaw cant be held in place with a cast as a broken arm can, oral
surgeons use tiny plates and screws to stabilize the fracture; sometimes
the patients mouth is wired together. As Mr. Heberling recovered
from the surgery, he found both: His jaws were wired, and a plate-and-screw
combination held his chin together. Gradually, the "hardware"
was removed, and a set of partial dentures was made for Mr. Heberling
by Dr. Cosmo De Steno, a prosthodontist and associate dean of clinical
affairs at New Jersey Dental School. Partial dentures are a temporary solution for Mr. Heberling. By summer,
hell have dental implants to replace his eight missing teeth. Implants
are artificial tooth roots that are surgically placed into the jaw to
hold replacement teeth. The implant process takes between three and six
months, and for Mr. Heberling, it began in February with a bone graft.
"A good bony structure and healthy gums are essential to an implants
success, because in time the jaw bone attaches to the implant to hold
it in place, a process known as osseointegration," says Dr. Ziccardi.
"Bill needed a bone graft to replace areas of jaw bone that were
missing because of the accident." Once Mr. Heberlings bone graft healed, the first phase of dental
implantation began: placing the artificial root into the jaw and covering
it with gum tissue. Once osseointegration has occurred, the root is uncovered,
and a post is attached and then capped with a permanent crown. Mr. Heberlings accident has left him with a stronger faith and
an even greater appreciation for his four children and his wife. He also
is thankful for Dr. Ziccardi and the other doctors at University Hospital
who "did an amazing job putting me back together." Mr. Heberling had surgery to repair his fractured jaw bones. But corrective
jaw surgery is not reserved for trauma cases. Many people have these corrective
procedures to enable them to eat more easily, speak more clearly, and
look more "in balance." "Orthognathic is a very precise word -ortho means straight
and gnathic refers to the jaw," says Dr. Ziccardi. "There are
a number of ways a persons maxilla or mandible the upper and lower
jaws can grow unevenly. There can be an underbite, an overbite, or a crossbite.
For others, the chin is either underdeveloped or overdeveloped. Through
surgery, the jaw or chin can be repositioned." According to the American Association of Oral and Maxillofacial Surgeons,
approximately 5 percent to 7 percent of Americans have dentofacial deformities
involving the jaw. A general dentist is usually the first healthcare professional to discover
a dentofacial deformity, but many people can see that their jaws are not
aligned properly by looking in a mirror. There are some other symptoms,
as well. "These patients may have difficulty chewing or be unable to bite
into a sandwich," notes Dr. Ziccardi."There can be excessive
mouth breathing, which can be drying to the gums and lead to gingivitis." The dentist makes a referral to the oral surgeon, who works in tandem
with an orthodontist to develop a treatment plan. At the New Jersey Dental
School, the Center for Dentofacial Deformities is dedicated to helping
people with misshapen jaws. Some people will need surgery and others are
helped by braces alone, but in both instances, orthodontics is involved.
"Most patients will wear braces for 6 to 12 months before surgery
to align the teeth and to optimize surgical movement,"says Dr. Ziccardi,
"and then for about another six months afterward to stabilize the
teeth and jaw bones." Corrective jaw surgery is most commonly done when patients are in their
late teens or 20s when jaw growth is complete. Using digital imaging technology,
the oral surgeon can show the patient a reasonable estimate of what he
or she will look like after treatment is complete. Orthognathic surgery is done in a hospital, and depending on the procedure
or procedures, takes from two to eight hours. At University Hospital,
a "bloodless" technique, hypotensive anesthesia, is used during
orthognathic surgery to reduce blood loss. It involves a controlled lowering
of a patients mean arterial pressure during surgery through various
agents, explains Dr. Ziccardi, who is affiliated with The University Center
for Bloodless Surgery & Medicine at University Hospital. Orthognathic
surgery typically requires an overnight hospital stay, followed by one
to two weeks of recovery time. In the past, the weeks following orthognathic surgery were considered
the most difficult part. The patients teeth and jaws were wired
together for several weeks to support the surgical movement. This was
uncomfortable and, with the patient able to have only liquids, sometimes
resulted in unwanted weight loss. Today, tiny plates and screws are used that fixate the facial bones in
a shorter amount of time and with a quicker return to a normal soft diet.
Once the post-surgical orthodontic work is complete and the braces are
taken off, the orthognathic patient has a more balanced-looking face and
a better ability to chew and speak normally. |
