Hmm, there's a few options. A thin but strong steel needle maybe could be hammered through her skull like a nail without the need for drilling.

It could go in from her nose cavity, from the back of her eye sockets (squeezed past the eyeball, not through) or from the very back of her mouth, going upwards.

Out is a different question. Going through the back of the skull, although it could easily be hidden by hair, is going to need much more force than going in through any of the described places. You could drill a hole from the outside, but then there's the issue of aligning the penetrating pole with the exit hole. You don't want to wriggle it around in your head until you found it, juicifying your brain in the process (that would certainly cause heavy bleeding, brain hemorrhage however is permanently debilitating and deadly)

It would likely be better to just hammer it through from the inside like a nail. But that only works with sufficiently narrow nails.

That would hurt though. A lot. Hammering anything through a bone, especially the skull is going to give a severe and lasting headache. Good torture method, but I don't think Tatjana would go that far.
