title: Three-dimensional virtual model and animation of penile lengthening surgery.
abstract: BACKGROUND
  Three-dimensional digital models, animations, and simulations have been used in the plastic surgical field for surgical education and training and patient education. In penile lengthening surgery, proper patient selection and well-designed surgical interventions are necessary; however, no such surgical or patient education tool exists.
  
  
  METHODS
  Using magnetic resonance images as references, a preliminary three-dimensional digital model of the penis with its adjacent structures was constructed using Amira 5. This preliminary model was imported into Maya 2009, a computer modeling and animation software program, for processing to correct many defects. The refined model was used to create digital animation of penile lengthening surgery, including ordered steps of the procedure, using Maya 2009 and Adobe After Effects CS4.
  
  
  RESULTS
  A three-dimensional digital animation was created to illustrate penile lengthening surgery. All major surgical steps were demonstrated, including exposure, transversal incision of the fundiform ligament, partial division and release of the suspensory ligament.
  
  
  CONCLUSIONS
  Three-dimensional digital models and animations of penile lengthening surgery may serve as resources for patient education to facilitate patient selection and resident education outside the operating room.
