|A minor abscess can sometimes heal without intervention; however, abscesses that do not spontaneously open and drain may require surgical incision and drainage. Drugs frequently are necessary to combat infection. Antibiotics are used for bacterial infections, antifungal drugs for fungal infections, and anti-amoebic drugs for amoebic infections. Drainage is performed either through an open surgical procedure or directly through the skin (percutaneous). Following drainage of a superficial or subcutaneous skin abscess, the wound is packed with gauze and left open to drain. Aftercare may include warm soaks or wound irrigation 3 to 4 times daily for 7 to 10 days, or until the wound heals (Doerr).|
Breast abscesses smaller than 3 cm are treated with needle aspiration and drainage, followed by antibiotic therapy; larger abscesses may require surgical excision (Miller). Repair of a gastrointestinal defect may involve closure of a perforation, or removal of the appendix. Most spinal abscesses are treated with antibiotic therapy before neurological complications occur, making surgical drainage and removal of the lamina (laminectomy) unnecessary.
