IntroductionThe field of wound healing and tissue repair has advanced rapidly in the last decade, with this there is an increasing emphasis on the importance of the functional and cosmetic outcomes following injury. Integra artificial skin is the most widely used synthetic skin substitute and is reported to have better outcomes in relation to the appearance and elasticity when compared to split thickness skin grafting (SSG). A review of the literature reveals very few trials that are based on an objective evaluation of Integra treated scars as compared to SSGs. This research aimed to provide objective data on the long-term outcome of Integra.MethodAll adult patients from the Welsh Burns Centre who had been successfully treated with Integra+/-SSG were invited to attend a clinic for a follow up provided they had been healed for greater than one year. The hypothesis that Integra scars are more pliable than skin grafts was tested objectively using the Cutometer, a suction device which measures skin elasticity.ResultsOf the 13 patients eligible, six were available for assessment. The results of this study suggest that Integra treated sites correlate well with normal skin as measured by the Cutometer. This was statistically significant for the parameters Ur/Ue (elastic function) and Ur/Uf (gross elasticity). On the other hand there was no correlation seen between the patients SSG sites and the patient's normal skin.ConclusionWith advances in medicine we are increasingly able to modulate wound healing and the resultant scars. In order to assess new and often costly treatments the need for objective scar measurement tools have become apparent. Integra has been advocated to improve scarring from injury. However, there have been few studies to evaluate the long-term outcome of Integra as compared to traditional methods such as SSG. In the past scar evaluation has been based on subjective scores by patients and clinicians. Now the mechanical properties of the skin can be evaluated using simple bioengineering methods such as the Cutometer Suction Device. Using this device our study has objectively demonstrated that the elastic properties of areas treated with Integra is comparable to normal skin.Copyright (c) 2009 Elsevier Ltd and ISBI.
