Bioengineered tissues are largely used in current clinical practice for tissue loss reconstruction in difficult cases where autologous grafts are unavailable or unsuitable. Artificial skin substitutes are generally used for the acute treatment of huge skin loss in patients in critical general conditions or for functional indications in secondary surgery. The authors present the daring use of a bioengineered skin substitute for exclusive aesthetic purposes in the reconstruction of the tip of the nose.

Background. Chronic wounds are being treated with bioengineering skin constructs. Yet, there is no standard way of assessing these wounds. We developed a classification system to evaluate wounds after construct application. The classification system evaluates the early clinical effect of bioengineered skin and early construct appearance giving a total score named the skin substitute score. Objective. Apply classification system to both venous and diabetic foot ulcers and determine whether classification system has validity and predictability for healing. Methods. Evaluated serial photographs in 83 and 78 patients with diabetic foot ulcers and in 84 and 83 patients with venous ulcer on Days 7 and 14, respectively, treated with a bilayered bioengineered skin construct. Applied the classification system and determined the percentages of healed patients. Results. There was a significant correlation between better skin substitute score and complete wound closure for both venous ulcers p=0.002 on Day 7 and p=0.01 on Day 14) and diabetic foot ulcers p=0.0005 on Day 7 and p

Background. Venous ulcers affect as many as 2.5 million people in the United States and can cause substantial pain and loss of function. Objective. To review current approaches to venous ulcers and compression. Method. Treatment options that have been proposed in the literature are discussed utilizing the Cochrane library database, Medline, and the author's clinical experience. Results. Diagnostic findings and management strategies for venous ulcers are reviewed. Conclusion. Good wound care and compression therapy will heal the majority of small venous ulcers of short duration. For ulcers that are slow to heal, other approaches such as venous surgery and grafting with conventional or bioengineered skin substitutes should be considered.
