  Three-dimensional cutoff regulators are frequently employed in multi-nucleon
calculations, but they violate chiral symmetry and Lorentz invariance. A cutoff
regularization scheme is proposed to compensate systematically at subleading
orders for these symmetry violations caused by regulator artifacts. This is
especially helpful when a soft momentum cutoff has to be used for technical
reasons. It is also shown that dimensional regularization can still be used for
some Feynman (sub)diagrams while cutoff regulators are used for the rest.
