Abstract
Controlled expansion is a technique that increases the area of local tissue available for reconstruction. An extension of this is to expand free flaps prior to elevation, thereby increasing their area. This has been particularly useful in children where there may be insufficient tissue available at free flap donor sites. Four children have had extensive cutaneous defects of the lower limb reconstructed with expanded parascapular free flaps. Measurements indicate an approximate doubling in skin area. There has been normal growth of the affected limbs and there has been no donor site morbidity. Apart from small areas of narrow marginal necrosis at the tip of the flaps in the first three cases, which were of no consequence, healing at the recipient site was complete.
