Gareee is right. For a simple hole or a camera peekaboo, transmaps will do the job, much more precisely and flexibly than fiddling the mesh.
For a wound or an excavation, transmap plus displacement will do. Especially since you can have both positive and negative displacements.
I can't think of a situation where you'd really need to alter the mesh.
