4. Z-plasty
• Uses:
– Increase the length of a scar
– Break up a straight line scar
– Realign a scar

5. Z-plasty
• 30 degrees----25% elongation
• 45 degrees---50%
• 60 degrees---75%
• 75 degrees---100%
• 90 degrees--- 125%

6. Simple Z-plasty
AB increased by 75%

7. Double-opposing Z-plasty
Increase by 75%

8. 5 Flap Plasty
75% for the Z’eds
50% for the VY
total: 125%

9. 4 Flap Z-plasty
50% for 1 Z-plasty of 45%
Therefore 100% elongation

10. 6 Flap Z-Plasty
3x50%
Therefore 150% in length
