I think that the term craniology has been adopted by quite a few professions since its original inception. You can see a craniologist these days and usually it will be a massage artist that specializes in holistic healing practices. They work to massage your skull lightly in order to bring your body more in line.
From what I have read a massage of the head is supposed to help with a huge variety of issues, from attention deficit disorder to heart disease. The idea is that by massaging the head to balance the craniosacral system you can reap numerous health benefits. I don't know if this works or not, but it certainly sounds interesting.
