EXCISION AND DRAINAGE
Of an abcess or cyst
EXCISION OF A CYST
A scalpel is used to make an oval cut on both sides of the cyst; care is taken not to rupture it. The cyst and its covering skin can then be carefully lifted while gently cutting them away from the underlying tissue. Any bleeding that occurs with removal is controlled with pressure, cauterization, or suturing. The skin is sutured together, and a dressing is applied.
DRAINAGE OF AN ABCESS OR INFECTED CYST
The wound is punctured and drained. Forceps are used to improve drainage and the cavity is explored to break down all small spaces. Samples of the pus can be obtained to identify the bacteria responsible for the infection (culture). After the cavity has been completely drained, it may be packed with gauze containing an antibacterial medication. The exterior wound should be kept open until the cavity heals from within. A dressing is placed over the area.
DANA CYST REMOVAL
Specifically for scalp cysts, a stab incision is made directly into the cyst cavity. The contents of the cyst are then manually removed. The cyst capsule, now smaller, can then be extracted through the small incision and the wound packed with gelfoam sponge. Stitches are not usually necessary for this small wound. Excision is recommended when the cyst is determined to be too large for Dana removal.
