  RESULTS
  The history of tissue expansion is briefly reviewed. Indications pertinent to the practice of dermatologic surgery are discussed. The devices themselves are described, as well as new experimental advances. The general procedure for utilizing tissue expanders is outlined, as well as relevant histologic changes that occur in expanded skin.
