A practical calculation method for predetermination of amount and duration of expander application

Expander application has become one of the methods most commonly used in reconstructive surgery by virtue of its many advantages. Determination of the amount and duration of expansion completely depends on a surgeon’s experience and clinical estimation. Interestingly, no quantitative method has been described in the literature. In an attempt to address this issue, I developed a practical calculation method for expander cases. I use this technique daily during the expansion process to decide whether or not to complete the procedure. By means of this practical method, I believe that expanders can be optimally and more effectively utilized in reconstructive surgery.
