'around the neck?' is the definition.
I can't tell whether this defines the answer.

'villain's head framed by a circle roughly' is the wordplay.
'head' indicates taking the first letters.
'framed by' is an insertion indicator.
'roughly' indicates anagramming the letters.
The first letter of 'villains' is 'v'.
'a'+'circle'='acircle'
'acircle' anagrammed gives 'cerical'.
'v' placed into 'cerical' is 'CERVICAL'.
