Postoperative Scar Management Protocol for Asian Patients.

BACKGROUND: Postoperative scar formation remains a morbidity for patients even with the advent of minimally invasive techniques. Furthermore, the significant difference between the Asian and Caucasian skin results in poorer postoperative scar outcomes in Asians, supporting the need for an evidence-based scar management protocol. METHODS: Following a literature review of the PubMed and the Cochrane databases over the past 10 years, we constructed a novel postoperative scar management protocol for the Asian skin, utilized in a Singaporean tertiary healthcare institution. RESULTS: We describe a timeline-based scar protocol from the point of skin closure to a minimum of 1 year of follow-up. We support the use of intraoperative botulinum toxin for selected high-risk individuals upon skin closure with a follow-up regimen in the postoperative setting. For recalcitrant keloids, we have described a multimodal therapy comprising elements of intralesional steroids, botulinum toxin, lasers, surgery, and radiotherapy. CONCLUSIONS: A consolidated postoperative scar management protocol provides the necessary guidance for improved scar outcomes in the Asian skin. There is inherent potential in expanding the protocol to include post-traumatic and burn wounds or support other skin types including the Caucasian skin.

The superior lateral genicular artery flap for reconstruction of knee and proximal leg defects

Reconstruction of defects around the knee region requires thin and pliable skin. The superior lateral genicular artery (SLGA) flap provides an excellent alternative to muscle-based flaps. The anatomy and the surgical techniques of the SLGA flap were reviewed and the results of cases using the SLGA flap for coverage of knee and proximal leg defects were analyzed. SLGA flaps were performed in two cases and followed up for at least 6 months. Twelve articles on the use of the SLGA flap were also identified. A review of 39 cases showed that the mean diameter of the perforator supplying the skin of the flap was 1.04 mm, while the mean diameter of the SLGA at its origin was 1.78 mm. The mean length of the pedicle measured from the origin of the popliteal artery was 7.44 cm. The average dimensions of the flap were 14.8×6.6 cm with primary closure of the donor site in 61.5% of cases. Of these cases, 38.5% were due to trauma, 23.1% were post-burn complications, 12.8% were defects after resection of tumors, and 10.3% were for ulcers post-bursectomy. The most common complication was flap tip necrosis. All studies reported favorable outcomes with complete wound healing.
