Type of surgery with which one may be faced anew (7)
I believe the answer is:
plastic
'type of surgery' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for plastic that I've seen before include "means of deferring payment" , "Credit card; mouldable" , "(Originally malleable) material" , "Credit cards are known as ....... money" , "non-metallic material" .)
