特重度烧伤后伴多处严重畸形的功能重建

Functional reconstruction of multiple severe deformities after extensive deep bum

To explore new measures for functional reconstruction of multiple severe deformities as a result of extensive deep burn( total burn surface area ≥90% TBSA, including deep burn ≥ 70% TBSA)in late stage. Twelve severe bum patients with above-mentioned deformities were hospitalized in our ward during 1960 ～ 2005,the sears resulted from bums 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 re search, we chose the following methods to correct deformities and restore functions: application of split-thickness scar skin after expansion(88 wounds) ; use of sear 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 appear ance and function were improved obviously without complica tions. Follow-up 1～ 40 years, all patients could take care them selves with satisfactory function and appearance, and among them 8 patients returned to work ( one had worked for 40 years),2 pa tients married and had children. The above-mentioned measures are safe, reliable and effective for functional reconstruction of deformities.
