Abstract:
Objective To summarize the experiences of repeated expansion surgery,to evaluate the changes of skin histological and biomeehanical properties,and to afford rationale for its application and popularization.Methotis Skin soft tissues were repeatedly expanded to repair the massive skin defection.All the 31 cases were divided into children group and adult group according to their ages.In each group the treatment experiences were summarized.The biomechanical and pathological properties were investigated and compared after samples had been made.Resuits A total of 31 cases were treated by serial tissue expansion.Complication incidences of every expanded procedure were 10%and 17%respectively.After 6-12months postoperative follow-up,most of the curative effects were satisfactory.The repeated expanded skin had lower enlarged rate,depressed stress-relaxation and stress-strength character,so was the deceased proliferation of the epidermal cells.The changes were significant in the adult group.Conclusions Repeated expansion is a feasible method of repairing the massive skin defection.Its curative effect is more satisfactory in children than adult.Due to the increase of the risk and skin quality decline,enough attention must be paid in clinical application.
