Exteriorization of the subdural pocket for chronic recurrent subdural hematoma

The author describes a new operative method for treating chronic recurrent subdural hematoma. The subdural pocket is exteriorized so that it is in continuity with the subgaleal space through a limited extradural pocket and an L-shaped linear craniectomy. This procedure has been carried out in two patients with recurrent chronic subdural hematoma, both of whom made complete recoveries despite initial recurrence of the subdural hematoma.
