This is not a business question. It's a health question.

The angle (degrees) of the central and lateral limbs of a simple z-plasty that allows for transposition of the flaps, with optimal balance between scar lengthening and skin flap ease of closure with minimal tension is 60 °.

60° z-plasty is the typical angle but there are z-plasties available that have 45° and 30° angles of their central and lateral limbs.

The purposes of the z-plasty are:

1) alters the direction of tissue tensions

2) changes the direction of scar lines
