Uvulopalatopharyngoplasty for Obstructive Sleep Apnea
Uvulopalatopharyngoplasty (UPPP) is a procedure that removes excess tissue in the throat to make the airway wider. This sometimes can allow air to move through the throat more easily when you breathe, reducing the severity of obstructive sleep apnea (OSA). The tissues that are removed may include:
The soft finger-shaped tissue that hangs down from the back of the roof of the mouth into the throat (uvula).
Some pain medicines can relax the throat muscles. You may have to avoid these medicines after surgery to make it less likely that your airways will narrow and cause apnea episodes.
Why It Is Done
Your doctor may suggest UPPP if you:
Have excess tissue in your nose, mouth, or throat that blocks your airway.
Choose not to use (or cannot use) CPAP.
Do not get better after using CPAP.
Do not want to have an opening made in your windpipe (tracheostomy) to treat sleep apnea.
Children usually do not have UPPP. For them, removing the tonsils and adenoids usually cures sleep apnea.
How Well It Works
UPPP may reduce sleep apnea in some people, but results are mixed.1, 2
UPPP may stop snoring, but apnea episodes may continue.
Even if surgery successfully removes the blockage, you may still need CPAP after surgery.
Complications during surgery include accidental damage to surrounding blood vessels or tissues.
Complications after surgery may include:
Speech problems. The surgery may result in a nasal quality to the voice.
Changes in how food tastes.
Swelling, pain, infection, or bleeding.
Narrowing of the airway in the nose and throat.
Sleepiness and periods of not breathing (apnea) related to the medicines that are used to relieve pain and help you sleep.
What To Think About
Before considering surgery, you should try CPAP.
You will need a sleep study after UPPP surgery to find out if your sleep apnea has improved. If you still stop breathing at night, you may still need CPAP.
Laser-assisted uvulopalatoplasty is sometimes used to treat mild to moderate obstructive sleep apnea, although not all people benefit. This procedure is not recommended by the American Academy of Sleep Medicine to treat sleep apnea.3
People who are obese or who have some other illnesses are more likely to have complications after UPPP.4
