There has been a long-standing need for guidelines on the diagnosis and treatment of keloids and hypertrophic scars that are based on an understanding of the pathomechanisms that underlie these skin fibrotic diseases. This is particularly true for clinicians who deal with Asian and African patients because these ethnicities are highly prone to these diseases. By contrast, Caucasians are less likely to develop keloids and hypertrophic scars, and if they do, the scars tend not to be severe. This ethnic disparity also means that countries vary in terms of their differential diagnostic algorithms. The lack of clear treatment guidelines also means that primary care physicians are currently applying a hotchpotch of treatments, with uneven outcomes. To overcome these issues, the Japan Scar Workshop (JSW) has created a tool that allows clinicians to objectively diagnose and distinguish between keloids, hypertrophic scars, and mature scars. This tool is called the JSW Scar Scale (JSS) and it involves scoring the risk factors of the individual patients and the affected areas. The tool is simple and easy to use. As a result, even physicians who are not accustomed to keloids and hypertrophic scars can easily diagnose them and judge their severity. The JSW has also established a committee that, in cooperation with outside experts in various fields, has prepared a Consensus Document on keloid and hypertrophic scar treatment guidelines. These guidelines are simple and will allow even inexperienced clinicians to choose the most appropriate treatment strategy. The Consensus Document is provided in this article. It describes (1) the diagnostic algorithm for pathological scars and how to differentiate them from clinically similar benign and malignant tumors, (2) the general treatment algorithms for keloids and hypertrophic scars at different medical facilities, (3) the rationale behind each treatment for keloids and hypertrophic scars, and (4) the body site-specific treatment protocols for these scars. We believe that this Consensus Document will be helpful for physicians from all over the world who treat keloids and hypertrophic scars.

Reconstructions for local recurrence and second primary oromucosal cancer remain a challenge because the recipient vessels are depleted in the neck. The objective of this study was to investigate the outcome of superficial temporal vessels, as reserve recipient vessels for microvascular surgery in vessel-depleted neck patients. Between March 2003 and August 2005, the superficial temporal vessels were used as a recipient site for microsurgical head and neck reconstruction in 15 patients with vessel-depleted necks. There was no flap loss in any of the reconstructions. One venous anastomosis was revised for thrombosis and flap salvaged. The superficial temporal vessels provide a good alternative for head and neck reconstruction in vessel-depleted neck patients with the advantages of radiation spared, constant anastomy, and suitable size. It obviates the need for long pedicle flaps or the use of vein grafts. Care must be taken not to damage or kink the vein.

Our experience suggests that the distal stump of the intramuscular motor branch of the obturator nerve may be useful for facial reanimation via double-powered free gracilis muscle flap transfer.
