zbrush - best way to make a hole and keep clean topology?

weee

for example, you dynamesh a head until you are happy with then you make a hole for eye sockets followed by zremesher, but it wouldn't generate a good topology around the hole.

have you tried using zremesher brush to draw guide lines for the zremesh operation?
sometimes it gives usable results, sometimes not.. when not, you will probably have to do it manually
