In Charlotte's case he was just drained of spirit energy to the point of near death, I don't remember a single wound on him and he was still healthy enough to have a whole mini-conversation with Yumichika.

Orihime's situation is a bit trickier to justify. They only implied Menoly's head was destroyed (I don't remember them showing the injury in detail) but even if it was death then Orihime has just shown she can bring back the freshly dead so far.
