title: [Computer-aided preoperative planning of tissue expansion].
abstract: OBJECTIVE
  The aim of this paper is to introduce a computer program developed to provide objective and quantitative data useful to provide proper expander selection when a rectangular tissue expander has to be used.
  
  
  METHODS
  The program has been developed to calculate the volume of a rectangular tissue expander to obtain the exact amount of yield necessary to allow for reconstruction of a determined defect. The only data to be supplied are the length and the width of the defect to be reconstructed.
  
  
  RESULTS
  The accuracy of the results obtained by the computer program was tested clinically comparing preoperative data with volume measurements obtained at the end of the expansion procedure. In our study the resulting data did not show any statistically significant difference (p<0,05) between the two groups.
  
  
  CONCLUSIONS
  In our opinion, although its use is not aimed at replacing clinical judgment based on experience and careful observation, this program may be considered a simple and useful adjunct for the inexperienced surgeon (or the occasional operator) planning to use a rectangular tissue expander.
