Corticosteroids may be a therapeutic option in the management of cSDH. There is very little data on the efficacy of corticosteroids in the treatment of cSDH and certainly no randomized trials. The purpose of the study is to prove dexamethasone can be just as efficacious as surgery in treating chronic subdural hematoma. The investigators also hope to show that those patients treated with dexamethasone suffer less complication compared to those who undergo surgery.
