Construction of MASAs almost orthogonal to a given subalgebra

Given an arbitrary countably generated II$_1$ factor $M$, an irreducible subfactor with infinite index $Q\subset M$ and $\varepsilon >0$, we construct an irreducible hyperfinite subfactor $R\subset M$ such that $R\perp_\varepsilon Q$. We derive from this the existence of singular and semiregular MASAs $A \subset M$ such that $A \perp_\varepsilon Q$.
