Spontaneous subdural hygromas: a complication following craniofacial surgery.

We present a case report of symptomatic, spontaneous subdural hygromas complicating craniofacial resection of a malignant skull base tumor. This complication occurs after prolonged spinal drainage instituted to prevent cerebrospinal fluid fistulas secondary to insecure dural repair. We believe that this complication may be seen repeatedly as indications for craniofacial surgery in the elderly continue to expand.
