Disfigured Omani woman (5)
I believe the answer is:
naomi
'woman' is the definition.
'disfigured omani' is the wordplay.
'disfigured' indicates anagramming the letters.
'omani' with letters rearranged gives 'NAOMI'.
(Other definitions for naomi that I've seen before include "Do I moan about Biblical Ruth's mother-in-law?" , "mother- in-law" , "Relative of Ruth" , "Girl" , "Biblical mother-in-law of Ruth" .)
