title: Repair of cerebrospinal fluid rhinorrhoea with pedicled dural flap.
abstract: Four cases of persistent cerebrospinal fluid rhinorrhoea through the ethmoid sinus are presented. Using the operative microscope, the margin of the dural defect was easily identified, and a pedicled dural flap supplied by branches of a meningeal artery was successfully sutured to the dural margin in a watertight fashion without increasing pre-existing neurological deficits. To prevent intracranial infection, the watertight closure with a predicled dural flap is presumably more complete and reasonable than are various grafts without vascular circulation.
