Genial Bone Advancement Trephine
Genial bone advancement trephine (GBAT) is a surgical option for treating sleep apnea, a disorder that causes brief interruptions of breathing during sleep.
What Does Genial Bone Advancement Trephine Involve?
During 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, making it easier to breathe. A multidisciplinary team of sleep disorder specialists, otolaryngologists and oral surgeons at Jefferson work together to come to a diagnosis and perform this procedure.
You may experience soreness after a GBAT, but you will not experience any change in the way your teeth fit together. Recovery time is usually about two weeks.
