1Medical College, Trivandrum, India.
Background:
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.
Conclusion:
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%.
