Abstract
Over a period of 30 years since 1966, 2300 cases of chronic subdural hematoma have
been seen and treated.
A male preponderance among the cases was seen, in a ratio of 5:1. The condition presented
with various manifestations. Nine hundred were seen in the pre-CT period (before 1980),
compared to 1400 cases encountered after 1980. Since 1968, these cases have been managed
by a small temporal craniotomy, with the dura left open and the subdural space communicating
with the subtemporalis area.
This procedure has resulted in marked reduction of recurrence, and membranectomy has
not been required. There have been 11 deaths in this group of patients; the mortality
rate is only 0.5%.
