We have been using the square scalp grafts for more than 10 years. They are an important technical advancement over the round punch grafts because they have 25% more hair than round grafts with the same diameter. The donor site is sutured and leaves only a lineal scar. In this way, grafts can be taken from the same place several times. The grafts are manipulated under magnification to minimize damage. The operation is performed under local anesthesia on an outpatient basis. © Williams & Wilkins 1987. All Rights Reserved.
