Surgical treatment of obstructive sleep apnea has not been overly successful.
The mainstay in the surgical treatment of OSA is the UP3. This procedure involves removing the uvula (the "hangy-down thing" in your throat) and some of the soft tissue in the back of your throat. This makes the air passage larger and allows air flow through the upper airway more easily, reducing the chances of obstruction.
When successful, UP3 is generally well accepted. A repeat polysomnogram should be performed to determine the success of the procedure.
