Jefferson specialists studying innovative surgery for effectively treating sleep apnea
August 29, 2007Sleep disorder and ear, nose and throat specialists at Thomas Jefferson University are examining an innovative procedure to treat obstructive sleep apnea syndrome.
In the procedure, known as Genial Bone Advancement Trephine (GBAT), a small portion of the lower jaw which attaches to the tongue is moved forward, to pull the tongue away from the back of the airway, increasing the airway space. It is considered an option for patients when medications or a continuous positive airway pressure (C-PAP) device, which increases the supply of oxygen and reduces the work of breathing, have proven to be ineffective.
"Even immediately after the procedure patients have an easier time breathing," noted Maurits Boon, M.D., Clinical Instructor in Otolaryngology-Head and Neck Surgery, Jefferson Medical College of Thomas Jefferson University. "We have also observed that in a select group of patients hypertension drops off."
This procedure is often employed as an adjunct to more conventional surgery and can be very effective at treating OSA (obstructive sleep apnea).
Sleep apnea is a breathing disorder characterized by brief interruptions of breathing during sleep. Obstructive sleep apnea occurs when there is collapse of upper airway structures that prevent normal airflow. This essentially, results in cessation of breathing with resultant decreases in oxygen in the blood stream. The consequence is that this pattern of breathing causes interruptions in the normal sleep cycle and makes it difficult to get a restful night of sleep
"Sleep apnea is a serious, potentially life-threatening condition that is far more common than generally understood, noted Karl Doghramji, M.D., director of Jefferson University Hospital's Sleep Disorders Center, which recently opened a new all-inclusive facility in Center City.
"Sleep apnea occurs in all age groups and both genders," said Dr. Doghramji, Professor of Psychiatry and Human Behavior, Jefferson "It is more common in men, although it may be under-diagnosed in women. It is estimated that as many as 12 million Americans have sleep apnea."
Early recognition and treatment of sleep apnea is important, as it may be associated with:
* irregular heartbeat
* high blood pressure
* heart attack
* stroke
In the GBAT procedure, a small window is made in the lower jaw and advanced forward, said Dr. Boon. Because the tongue is attached to this portion of the jaw, it effectively moves the tongue forward to open the airway.
In this procedure, the surgeon is able to go through the inside of the mouth, avoiding the need to make any external incisions and avoiding any cosmetic changes. The procedure is usually done in conjunction with an uvulopalatopharyngoplasty-- surgery used to remove excess tissue at the back of the throat (tonsils, uvula, and part of the soft palate).
The piece of bone along with the attachment for the tongue is pulled forward and down, then fastened to the outside of the lower jaw. A small titanium plate is used to affix the bone.
The patient may experience soreness but will not have any change in dental occlusion (the way the teeth fit together), said Dr. Boon. The recovery period is usually about two weeks.
Three to six months after the procedure, follow-up sleep tests are performed.

Sleep Apnea Current Events and Sleep Apnea News RSSEye conditions linked with obstructive sleep apnea
If a good night's sleep helps the brain and body perform better, it's a good guess that sleep problems can cause more than just fatigue. Numerous studies have shown a connection between sleep disorders and medical conditions such as cardiovascular disease, cerebrovascular disease, and metabolic disorders, including the risk of obesity and diabetes mellitus. In the November issue of Mayo Clinic Proceedings, Mayo Clinic researchers outline several interesting associations between sleep disorders and eye disease.
Sleep Apnea May Be Risk Factor for Sudden Cardiac Death, Mayo Clinic Research Concludes
After studying the sleep characteristics of nearly 11,000 adults in an overnight sleep laboratory, Mayo Clinic researchers suggest that obstructive sleep apnea (OSA) - and, in particular, the low nighttime oxygen saturation of the blood it causes - may be a risk factor for sudden cardiac death (SCD).
Smokers see decline in ability to smell, rise in laryngitis, and upper airway issues
As Americans prepare for a day without cigarettes and tobacco products as part of the American Cancer Society Great American Smokeout (R) (November 20), new research gives them more reasons to extend that break to a lifetime.
New drug target in obesity: Fat cells make lots of melanin
As millions of Americans gear up for the Thanksgiving holiday, a new research report published online in The FASEB Journal, may provide some relief for those leery of having a second helping.
Green neighborhoods may reduce childhood obesity
Childhood obesity can lead to type 2 diabetes, asthma, hypertension, sleep apnea and emotional distress. Obese children and youth are likely to be obese as adults, experience more cardiovascular disease, high blood pressure and stroke and incur higher healthcare costs.
Neighborhood greenness has long term positive impact on kids' health
In the first study to look at the effect of neighborhood greenness on inner city children's weight over time, researchers from the Indiana University School of Medicine, Indiana University-Purdue University Indianapolis and the University of Washington report that higher neighborhood greenness is associated with slower increases in children's body mass over a two year period, regardless of residential density.
Even mild sleep apnea increases cardiovascular risk
People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study from the Oxford Centre for Respiratory Medicine in the UK.
Association found between severe obstructive sleep apnea
A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that unrelated to obesity, people with severe SDBs consume a more unhealthy diet, which may be a factor contributing to greater cardiovascular morbidity and mortality. These findings were most evident among women.
New light on link between snoring and cognitive deficits in children
About two-thirds of children with sleep-disordered breathing (SDB)- snoring or obstructive sleep apnea (OSA)- have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the SDB.
Scientists discover why a mother's high-fat diet contributes to obesity in her children
New research published online in The FASEB Journal suggests that pregnant women should think twice about high-fat foods.
