If you are editing using Photoshop or another layers-capable program you could 
make a copy of the image to a second layer and apply sharpening only to that 
copy layer.  While viewing sharpened layer zoom in on areas needing work, then 
switch to underlying unsharpened image and apply retouching there.  Discard 
sharpened layer when finished.
