Fig. 13.15 (a) Donor strip is incised using a single blade being careful to keep blade parallel to the hair follicles. Notice that the end of the strip is tapered. (b) The strip is being dissected out ensuring that the blade is 1–2 mm below level of the follicle bulb

leaving some fat surrounding the bulb and avoiding deeper blood vessels and nerves. The assistant applies strong counter traction with the use of the tissue clamp. (c) Strip is removed and any stray hairs or hair spicules are removed from the wound

accordingly. When patients return after many years, having had the original punch graft excision technique performed, previous circular punch scars that leave intact hairs between excised rows, and between grafts on the same rows, can be excised. The current strip excision techniques can benefit this type of patient twofold: (1) By re-excising and minimizing old punch scars and (2) making available more reusable donor hair.

After the wound has been sutured closed, any trapped hairs under the suture are carefully freed. The area is then cleansed with a dilute hydrogen peroxide mixture applied from a spray bottle. At this juncture, if a second strip is to be taken from a temporal site, the patient’s

head is taken out of the prone pillow and turned to one side for the next excision. Otherwise, if donor excision is complete, then the patient is turned over on to their back to wait while the strip is being dissected until such time as the recipient site is anesthetized.

13.12 Follicular Unit Extraction

Follicular unit extraction (FUE) is a relatively new technique that uses small circular punches to core out donor grafts one at a time. Unlike the original punch

Fig. 13.16 (a) Trichophytic closure technique showing the inferior border of the wound being trimmed at a 45° angle to create a triangular strip 1 × 1 mm. (b) The strip is being trimmed to de-epithelialize one to two follicular units. (c) Following single-layer closure

grafts that were 3.5 –4.0 mm in diameter, FUE employs a 0.7 –1.0 mm punch. Because the site created is so small, sutures are not required and the wound is allowed to heal by secondary intention.

13.12.1 Indications for FUE

1.Wanting to avoid linear scalp donor site scar

2.Limited recipient area dictating the need for fewer grafts: eyebrow, eyelash, and moustache

3.Due to excessive scarring in donor area, further linear scars are not appropriate

4.Use of non-scalp hair, that is, chest, back, and beard

5.To thicken widened scars in donor area from traditional excisions that cannot be re-excised

13.12.2 Advantages of FUE

1.Tiny 0.7–1.0 mm incision

2.No sutures required

3.No linear scar in donor area

4.No or minimal tension in donor area

5.Possibility of wearing hair in donor area very short

13.12.3 Disadvantages of FUE

1.Higher percentage of follicular transection and ingrown hairs compared to FUT

2.Time consuming and more costly to patient
