Z-plasty

• 30 degrees----25% elongation• 45 degrees---50%• 60 degrees---75%• 75 degrees---100%• 90 degrees--- 125%

Simple Z-plastyAB increased by 75%

Double-opposing Z-plastyIncrease by 75%

5 Flap Plasty75% for the Z’eds

50% for the VYtotal: 125%

4 Flap Z-plasty50% for 1 Z-plasty of 45%

Therefore 100% elongation

6 Flap Z-Plasty3x50%

Therefore 150% in length
