Chapter 2 The Sleeping Wife(10)

Steven examined the cranium cautiously, “As expected it is, come here to see, what’s the abonormity with the skull basal?” When Steven said that, I looked at there “No…nothing wrong with it, without any head fractures.”
 “At the skull basal the protuberances of the both sides are called petrous part of temporal bone.” Steven pointed to the petrous part of temporal bone with the hemostatic forceps and said, “Here under the cranium corresponds to the internal ear. If she was suffocated to death or drowned to death. The air pressure of the internal ear would be change and lead to hemorrhage at the petrous part of temporal bone. If the diseases lead her to sudden death, the air pressure of the internal ear wouldn’t change, and no hemorrhage would happen at the petrous part of temporal bone.”
I nodded; I was the winner on the examination of topographic anatomy in my class. The hemorrhage at the petrous part of temporal bone theory is easily understood. Looking at the black petrous part of temporal bone, I said “Yes, there was obvious hemorrhage at the petrous part of temporal bone, otherwise, this should be white not black.”
Steven nodded with approval, “Yes, she was smothered to death.”
