title: An experimental model of scalp expansion: a method of optimizing flap size and shape.
abstract: An experimental model has been developed for testing and comparing the placement and characteristics of expanders for soft-tissue advancement. Expanders are fixed to model heads and covered with a stockinet sleeve, and the sleeve is impregnated with prevulcanized latex. The resulting stockinet-latex has many of the physical properties of skin and can be manipulated to ensure optimal covering and suture length prior to surgery. The system is rapid and reliable. Several types of scalp flaps were tested using the model. The models can be used in teaching and prior to surgery. Their use ensures an à la carte expansion that minimizes the risk of expansion failure.
