RT Journal Article SR Electronic T1 Biodegradeable temporising matrix use in a traumatic chest wound JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e246691 DO 10.1136/bcr-2021-246691 VO 14 IS 12 A1 Eliot Carrington-Windo A1 Sam Leong A1 Nader Ibrahim A1 Sophie Pope-Jones YR 2021 UL http://casereports.bmj.com/content/14/12/e246691.abstract AB The Welsh Centre for Burns and Plastic Surgery is responsible for a population of 10 million people in Wales and England. We describe the use of biodegradable temporising matrix (BTM) in a large traumatic chest wound in a 23-year-old woman. BTM is a synthetic dermal substitute and has been utilised to achieve soft tissue coverage in complex wounds. This wound was sustained after the patient fell from a tractor into a large silage rake, resulting in injuries to her chest and limbs. Following meticulous debridement, her resulting full thickness skin defect measured 30 × 30 cm extending from the sternal notch to the upper abdomen, with bone, muscle and breast tissue exposure. The central chest area is complex to reconstruct due to the contours of the breasts and tendency to contracture following skin graft reconstruction. We demonstrate the first reported use of BTM for breast reconstruction, as far as we are aware.
