From what I’ve seen, it’s a mix of both planning and precision. A friend of mine who works in a clinic mentioned that modern tools combine imaging with real-time guidance, so doctors can see exactly where they’re going and avoid sensitive areas. That alone reduces a lot of potential complications. Some systems even help map out the procedure in advance, which adds another layer of safety. I read a bit more about how these technologies work while browsing
