Jaw Surgery (Orthognathic Surgery) for Sleep Apnea - NYC SleepWell

Показать описание

Jaw surgery, also called orthognathic surgery, is primarily known for treating TMJ, speech problems, over bites, underbites, and aesthetic issues such as a protruding jaw or small chin. It can also be very effective for treatment of breathing problems, snoring and obstructive sleep apnea (OSA). In fact, recent studies have shown that orthognathic surgery has more than a 90% success rate when treating sleep apnea patients. There are variations of orthognathic/jaw surgery. Maxillomandibular advancement, which moves the upper (maxilla) and lower (mandible) jaws forward to enlarge the airway, is known to provide the greatest improvement in treating sleep apnea. Because the recovery is typically more prolonged than other procedures and carries a different set of potential risks, maxillomandibular advancement is generally performed in patients who have not achieved sufficient improvement in their sleep apnea after other procedures. However, in some patients with jaw abnormalities, it can be a first-line surgical treatment. For severe sleep apnea, maxillomandibular advancement surgery averages close to a 90% success rate in therapeutic reductions of AHI levels. AHI is the Hypopnoea Index used to indicate the severity of sleep apnea by measuring the number of apnea events (temporary cessations of breathing) per hour of sleep.
