You'd kind of forget your headache. I saw a program a while back, like years ago, about some primitive culture in which trepanning, which is what this procedure is called, was still going on. It was done to relieve pressure in the skull of someone who had gotten hit on the head before swelling could cause death or brain damage. I remember what happened was that a woman was sitting casually on a rock, she had been hit on the head that day, and some dude came up and broke a hole in her skull while she sat there (I didn't see that part, my eyes having been covered up), and after it was done she walked casually back to her hut to rest. I just put trepanning into google and found this very fascinating link. epub.org.br I think this sentence must be referring to one of the tribes I saw on, probably, the Discover Channel.In the South Seas and in North African tribes (rifkabyla and hausa) and Kenya (kisi), trepanning is carried out particularly for relieving war wounds inflicted to the head. ,... My God, though, look at the track record of this guy Mery:It is hard to believe, but judging from the number of skulls which showed healing and bone regeneration at the borders, the proportion of "patients' who survived the ordeal of a trepanning was quite high, from 65 to 70 %. Out of 400 skulls examined by one researcher, 250 indicated recovery. In modern times (14th to 18th centuries) this proportion was much lower, sometimes approaching zero. Birner (1996) cites that a professional "trepanator" named Mery , lost all his patients in 60 years of activity. The most common cause of death was infection of the meninges or of the brain, or hemorrhage. According to this link it takes from 30 to 60 minutes of continuous sawing or drilling if it's done in a single session. But sometimes it was done over 12 days. It's hard to imagine. I think I'll never complain again.
