[Management of complications of expansion]

Although the complication rate during skin expansion has decreased, they can still occur. The authors describe the various possible complications. Complications during insertion of the expander include skin effraction, infection, pain and filling difficulties. During the filling phase, they consist of infection, leaks, cutaneous ischaemia, ulcerations underneath folds of the prosthesis, valves or tubing. Insufficient filling and impairment of the arterial or venous blood supply of the flap can occur during the final operation. Long-term complications essentially consist of persistent oedema, filling of the reconstructed contours, widening of scars, loss of sensitivity and occasionally bone deformities induced by compression. The prevention of these complications is based on an irreproachable technique and regular follow-up.
