title: Experimental pretransfer expansion of free-flap donor sites: I. Flap viability and expansion characteristics.
abstract: Expansion of cutaneous and myocutaneous free-flap donor sites prior to elevation is possible in the pig model. There is no significant difference in survival between control and expanded cutaneous buttock and myocutaneous latissimus dorsi flaps after elevation solely on their axial pedicles. Axial-pattern flap expansion appears to augment capillary blood flow. The maximum amount of expansion occurs directly over the center of the expander and decreases toward the periphery. There is virtually no expansion of skin adjacent to the expander.
