The throat is surrounded by soft tissues and muscles that relax during sleep, especially deep sleep. Muscle relaxation during sleep allows the muscles and soft tissues around the throat to flutter and cause snoring or to collapse and block ... Read More »

Maxillomandibular advancement (sometimes called jaw advancement or bimaxillary advancement) is often performed in patients who have not obtained relief from other procedures for sleep apnea. In this procedure, the upper and lower jaws are moved forward, enlarging the space for breathing in throat. It may also be a first-line treatment for patients who have jaw ... Read More »

Tongue Radiofrequency

Tongue radiofrequency uses controlled cauterization to tighten and shrink tongue tissues. This makes the tongue less likely to fall backward and block breathing during sleep. Tongue radiofrequency typically requires two to three treatment sessions. There are multiple technologies, ranging from Coblation™ to Somnoplasty™. The procedure can be performed in an operating room under general anesthesia ... Read More »

Midline glossectomy — using various techniques, including lingual tonsillectomy and submucosal lingualplasty — is performed in patients with large tongues who have obstructive sleep apnea. The tongue can be enlarged for a number of reasons, whether due to an increase ... Read More »

Lingual Tonsillectomy

In some patients, the lingual tonsils (tonsils on the back of the tongue) may be enlarged. This can contribute to obstructive sleep apnea by blocking breathing during sleep. In a lingual tonsillectomy, the lingual tonsils are removed to enlarge the airway behind the tongue.

Hyoid Suspension

The hyoid bone is a U-shaped bone in the neck located above the thyroid cartilage (Adam’s apple). The hyoid bone is attached to important structures, but the bone itself is not held firmly in position. Because the hyoid bone has this ability to move around, the structures attached to it can contribute to obstructive sleep ... Read More »

Genioglossus Advancement

Genioglossus advancement is a procedure that addresses the tongue and its tendency to fall backwards and block the breathing space in obstructive sleep apnea. The genioglossus is the major muscle of the tongue, and it attaches on the inside of the mandible (lower jaw bone). Genioglossus advancement involves making small cuts in the mandible to ...
