Abstract

PURPOSE
It is well known the advantages of scalp donor split thickness skin graft(STSG) in deep burn wound because of its scarless donor healing, and good color match in face. Inspite of the advantages of scalp as a skin donor site during split thickness skin graft some authors report the frequent postoperative folliculitis, and partial alopecia on scalp donor site. We had experienced 21 burn patients, who had full thickness skin defects caused by burn injuries, were successfully managed with scalp donor split thickness skin graft with our optimal donor management protocols.
METHODS
We had 21 deep burn patients, who were managed with thin STSG from scalp donor for coverage of full thickness skin defects. The operative techniques of the harvesting scalp STSG, and scalp donor dressing care are such as followings. After the infiltration of the donor scalp area with 1:1,000,000 epinephrine diluted with saline, then usually 0.012~0.015 inch thickness skin were harvested with air driven Zimmer® dermatome. On postoperative 6days, the one layer of adhered Vaseline gauze at donor scalp site was manually removed, and the entire scalp was cleansed with water. After then the daily hair washing was continued to remove the desiccated scaly crust with thick exudate at the growing hair and follicle.
RESULTS
The scalp split thickness skin graft at the recipient sites in 21 burn patients were survived completely. Ranges of patient's age were 8 months to 56. The size ranges of scalp STSG were 2Ã—2 cm~12Ã—15 cm. The grafted scalp donor STSG were survived in all cases. The mean epithelialization period of scalp donor was 7.2 days. The one case of transient folliculitis (5%) from the postoperative 8days was occurred, and it was disappeared slowly with vigorous daily hair washing, antiseptics and systemic antibiotics. In all cases, there was no micro-alopecia or alopecia, and scars in scalp donor after follow ups. The donor site pain was markedly disappeared within 1~2 postoperative day. The hemorrhage from the scalp donor site during operation was not noticeable. The newly growing hair at the scalp donor was noted from the 3 postoperative days by palpation or unaided eye through the Vaseline gauze dressing. The average lengths of newly growing hair shaft are 2~3 mm in postoperative 8 days, 5~6 mm in postoperative 14 days.
CONCLUSION
We had successful reconstruction of postburn skin defects using scalp donor split thickness skin graft without donor scars, persistent folliculitis or alopecia on scalp donor. From the postoperative 6~7 days after harvesting the scalp donor STSG, early vigorous daily washing with water and open dressing of scalp donor site should be recommended in order to prevent folliculitis. After long-term follow ups, the scalp split skin grafted recipient sites showed reliable, and relatively good color match with surrounding skin in face and dorsum of hand.
