Anatomy in surgical education
Anatomy in Surgical Education Training

Knowledge of anatomy/exposure essential

Time devoted to anatomy decreasing

Interns lack adequate knowledge

Cadaveric dissection is irreplaceable


Cadaver based education
Cadaver-Based Education Training

  • Ideal model for surgical skills training

  • Support basic and complex operations

  • Superior to other models / simulators

  • - Realistic

  • - Provides haptic feedback

  • - Representative surgical anatomy


Specific aims
Specific Aims Training

  • Describe UCLA Surgery anatomy program

  • Assess resident attitudes toward program

Preferred session format
Preferred Session Format Patient

  • Perform dissection under direct supervision

  • Self-guided dissection and

  • review of findings with instructor

  • Watch instructor perform a dissection









Future directions
Future Directions Patient

  • Continue to expand curriculum

  • Dedicated facility nearing completion

  • Program validation using surgical skills

  • assessment and demonstration of

  • improved operative performance


Summary cadaver based education
Summary: Cadaver-Based Education Patient

  • Efficient and effective educational tool

  • Useful in teaching anatomy, surgical skills,

  • complex open & laparoscopic procedures

  • Increase confidence in performing operations

  • Positive perception by residents

  • More effective than other learning modalities
