The link of an isolated stratum of a closed two-dimensional pseudomanifold is a finite disjoint union of circles. Separate these branches, replacing the cone on their union by separate disks. This produces a closed surface and a finite surjective map to the original space, a homeomorphism on the regular stratum. Orientations on the regular stratum extend over the disks.
