The abscess drainage procedure itself is fairly simple:

Your doctor makes an incision through the numbed skin over the abscess.
Pus is drained out of the abscess pocket.
After the pus has drained out, your doctor cleans out the pocket with a sterile saline solution.
The abscess is left open but covered with a wound dressing to absorb any more pus that is produced initially after the procedure.
A deeper or larger abscess may require a gauze “wick” to be placed inside to help keep the abscess open. This allows the tissue to heal properly from inside out and helps absorb pus or blood during the healing process.
Your doctor may send a sample of the pus to a lab for a culture to determine the cause of the bacterial infection.
