"Stretch-back" in scalp reductions for male pattern baldness.

"Stretch-back" is a phenomenon which to a considerable extent reduces the benefits of scalp excisions for reduction of male pattern baldness. Tattoo marks placed on the scalp have revealed that about one-third to one-half the effect of the excision of the bald area of the scalp is lost postoperatively. Most of this stretch-back occurs during the first 8 postoperative weeks and is completed at 12 weeks. Most of the stretch-back originates from the wound area. It is important to be aware of the stretch-back for correct planning of the surgical program and for being able to predict the final result.
