What Is OSA?
During sleep, the upper airway can be obstructed by excess tissue, large tonsils and/or a large tongue. Also contributing to the problem may be the airway muscles, which relax and collapse during sleep, nasal passages, and the position of the jaw. The cessation of breathing, or “apnea,” brought about by these factors initiates impulses from the brain to wake the person just enough to restart the breathing process. Sleep apnea is generally defined as the presence of more than 30 apneas during a seven-hour sleep. In severe cases, periods of not breathing may last for as long as 60 to 90 seconds and may recur up to 500 times a night.
Depending on whether your OSA is mild, moderate or severe, your OMS will select the treatment that’s best for you. This can range from behavior modification to oral appliances to an air pressure device. Surgery may be a good alternative for some patients, but it’s important to keep in mind that no surgical procedure is universally successful. Every patient has a different shaped nose and throat, so before surgery is considered your OMS will measure the airway at several points and check for any abnormal flow of air from the nose to lungs.
An OMS has considerable experience and the necessary training and skill to perform the following surgical procedures:
- Uvulopalatopharyngoplasty (UPPP) – This procedure shortens and stiffens the soft palate by partially removing the uvula and reducing the edge of the soft palate.
- Hyoid Suspension – The hyoid bone is located above the level of the thyroid cartilage (Adam’s apple). The procedure secures the hyoid bone to the thyroid cartilage to help stabilize this region of the airway.
- Genioglossus Advancement (GGA) – This procedure tightens the front tongue tendon, reducing the degree of tongue displacement into the throat. This operation is often performed in tandem with at least one other procedure such as UPPP or hyoid suspension.
- Maxillomandibular Advancement (MMA) – This procedure surgically moves the upper and lower jaws forward along with the soft tissues of the tongue and palate, opening the upper airway. For some patients, the MMA is the only technique that can create the necessary air passageway.
