[Functional reconstruction of multiple severe deformities after extensive deep burn].

To explore new measures for functional reconstruction of multiple severe deformities as a result of extensive deep burn (total burn surface area > or = 90% TBSA, including deep burn > or = 70%TBSA) in late stage. Twelve severe burn patients with above-mentioned deformities were hospitalized in our ward during 1960--2005, the scars resulted from burns were distributed from head to foot with 173 deformities, including 27 scar ulcers. All patients lacked of self-care ability, among them some could not stand. Due to inadequate skin source, deformities were corrected by skin from matured scars expanded with subcutaneous balloon at late postburn stage. Following our former clinical experience, anatomic investigation and experimental research, we chose the following methods to correct deformities and restore functions: application of split-thickness scar skin after expansion (88 wounds); use of scar skin flap/scar-Achilles tendon flaps (59 wounds); combination of thin split-thickness skin grafts from scar and allogeneic acellular dermal matrix (composite skin, 40 wounds). All grafts survived, the appearance and function were improved obviously without complications. Follow-up 1-40 years, all patients could take care themselves with satisfactory function and appearance, and among them 8 patients returned to work (one had worked for 40 years), 2 patients married and had children. The above-mentioned measures are safe, reliable and effective for functional reconstruction of deformities.
