Incisional Slit Grafting

Abstract

Incisional slit grafting, a new and greatly improved technique in hair transplantation, is described. Incisional slit grafting utilizes larger numbers of smaller grafts than does traditional punch grafting. No tissue is removed from the recipient bed. The vascular supply is conserved, resulting in an increased graft yield. The clumping and stalking effect associated with traditional round grafting is eliminated largely, and a more natural frontal hairline is achieved.

Follicular-Unit Hair Grafting

“…[3][4][5][6] Unlike those techniques that preceded it, the micro/minigrafting technique, popularized in the early 1990s, has come close to accomplishing the goal of undetectability. 7,8 With this technique, currently used by most hair transplant surgeons, micrografts containing 1 or 2 hairs are placed along the hairline, while the remaining areas are transplanted with minigrafts containing 3 to 5 hairs.…”

Nontufted Incisional Slit Grafting

“…This approach also demonstrated that using smaller grafts would require a larger number of grafts. Another technique developed was called “slit grafting” 3 or “incisional slit grafting.” 5 In place of holes, slits made with a scalpel were used for the recipient site. One initial problem with slit grafting was that the “pie‐shaped” grafts produced from quadrasected round grafts did not match the shape of the linear slits.…”

Curly Lusterless Hair: Anatomic Surface Changes on Transplanted Hair Shafts

“…This trimmed hair was taken from the left occipital scalp (corresponding to a row of 15 grafts) and was set aside for light and scanning microscopic examination. The donor grafts were harvested and transplanted according to an already described technique 1,2 . A total of 40 4.5 mm round grafts were harvested from each patient and then quadrisected resulting in 160 quarter grafts.…”
