A revascularization technique used to treat cerebral ischemia due to Moyamoya Disease. The technique consists of dissecting a segment of the temporalis muscle with the the superficial temporal artery attached  without disturbing its vascular flow. The muscle is then laid down onto the exposed cortical surface after performing a craniotomy and dural opening. It can be held in contact by sewing the muscle to the cut edges of dura prior to closing the surgical wound.
