As an alternative, left of the nose (5)


I believe the answer is:

'of the nose' is the definition.
(I've seen this before)

'as an alternative left' is the wordplay.
'alternative' indicates anagramming the letters.
'left' becomes 'l' (common abbreviation).
'asan' anagrammed gives 'nasa'.

(Other definitions for nasal that I've seen before include "Part of helmet", "Describing some hooter", "Hooters", "Pertaining to the nose", "Like sounds of m, n, ng".)

I've seen this clue in Mirror.
