A three‐dimensional scar assessment tool for keloid scars: Volume, erythema and melanin quantified

Background There is no non‐invasive objective assessment tool to measure keloid scar characteristics over time. This study aimed to ascertain the ability of the Antera 3D® camera to detect differences in keloid features pre‐ and post‐steroid injection. In order to identify whether those variation could be considered as treatment response predicting factors. Methods Enrolled patients received three intra‐lesional steroid injections at four‐weekly intervals. Images were taken with the Antera 3D camera 12 and 24 weeks after treatment. Keloids’ colour, volume, and area as well as haemoglobin and melanin average levels and variation have been analysed pre‐ and post‐steroid injection. t Tests and relative risk have been used to analyse the significance and association strength of our finding. Results Forty patients have been enrolled in the study. Significant changes as been recorded in keloids’ volume and colour after steroid injection (P
