Polynomial Cysts from Failed Operations

Cysts are balloonlike structures with sturdy membranes containing liquids, semisolids, or even gases. Some cysts are so tiny that they can be seen only with a microscope. Others are so big that they can compromise normal surrounding tissue, including skin and internal organs. Polynomial cysts are found near the tailbone, and can be very painful, especially when sitting down.

Your doctor may recommend one of the following treatments:

•  Corticosteroid injections, which may cause the cyst to shrink and disappear.

•  Laser surgery. Your doctor uses a carbon dioxide or other laser to obliterate the cyst, which may minimize scarring on the face or other visible body parts.

•  Lancing. Your doctor cuts and drains the cyst, which then must be covered with sterile bandages and treated with antibiotics.

•  Surgical techniques. These include minimal excision, which involves lancing and draining the cyst, then removing only the cyst membrane. Total excision—a more invasive technique—involves removal of the entire cyst and requires stitches.
