The first ref is a letter to the editor….

The second I cannot access from here (but maybe through the library) I’ll try to remember to give it a go Monday.

Yeah, I thought it was interesting for someone to be begging the editor for further studies into the phenomenon of people breaking their own facial bones. I didn’t realise people were breaking their own bones, I thought they were paying a maxillofacial surgeon with no morals to do it.
