Is it possible to remove scars through skin expansion?

As done with certain burn victims is it possible to use a ballon expander to stretch the skin where self harm scars are, then later cutting the excess skin thus removing the scars and leaving a surgical scar instead.

The use of tissue expanders is often done when trying to reduce the appearance of wide scars that cannot be removed by excision alone.  However, the result of doing this still leads to a scar.  The hope when doing this is that the scar will be a fine linear scar rather than a wide scar, which is more noticeable.
