#One should saw through the skull completely, i.e. one should not "crack" the skull open with a chisel. | |||
#*Cracking open the skull may result in artefactual fractures that are impossible to differentiate from antemortem fractures. | |||
#*Cuts into the brain (from opening the skull) are not difficult to distinguish from antemortem injuries. | |||
#Cranial nerves should be cut. | |||
#Tentorium should be released. | |||
#Spinal cord should be completely cut as far down as possible. | |||
#Dura should be stripped from the skull base. | |||

====Procedure==== | |||
Up-down anatomically oriented (right side-up): | |||
#Examine meninges. | |||
#Remove dura. | |||
#Examine venous sinuses. | |||
#Look for gyri effacement - due to edema or haematomas. | |||
Not up-down anatomically oriented (top down): | |||
#Remove brain stem - with one cut ~ at level of mid-brain. | |||
#Cerebrum section - first cut at mammillary bodies. | |||
#*Subsequent cuts ~ 1.0 cm in thickness. | |||
