People with facial injuries who wear prosthetics to replace features such as an eye or a nose have had their portraits unveiled in Leeds.
A group of 15 patients treated for head and neck cancer took part in research asking them to compare the comfort of prosthetics made using different methods.
As part of the study, their portraits were painted to help convey the physical and psychological impacts of their treatment.
Following the scheme, run by Leeds Teaching Hospitals NHS Trust and the University of Leeds, the artworks have gone on display in the Bexley Wing at St James's University Hospital.
