AbstractIn 20 patients with burn scars and 1 patient with a fresh burn, 33 tissue expanders were implanted. In 16 patients, the expansion fulfilled the goal set with the help of 27 expanders. The results are very satisfactory, but the effort of treatment and the trouble are substantial. Thirteen patients encountered no complications. In terms of expanders, there were 6 major and 11 minor complications. They were infection (three), wound dehiscence (two), insufficient expansion with hematoma (one), leakage (six), superficial skin damage (three), and intercurrent hematoma formation (two). There was no flap necrosis, and thus, apart from superfluous surgery, no real damage. Retrospectively, the major complications could have been avoided by more careful observance of indications. Unfortunately, this seems to be a process that every surgeon must learn by experience and not by theory alone. Here, infection was managed by removal of the expanders. Hematomas should be evacuated early (we drained most expanders), and incidences of leakage can be diminished by using larger valves. Small incisions in healthy tissue for expander insertion may lead to faster onset of expansion, thus, shortening the procedure. Late widening of scars was found only once, perhaps due to a rather long duration of expansion, averaging 13 weeks.
