[Cranioplasty using preserved subaponeurotic bone plate].

Cranial bone defect in 6 patients (5 males and 1 female) was repaired with preserved subaponeurotic bone plate. The defect was caused by evacuation of hematoma (5 patients) and resection of pituitary tumor (1 patient). Bone plates used measured 5-8 x 6-10 cm, and preserved for 57-92 days. Microscopic examination showed that the bone plates was alive, and small blood vessels were connected with two aponeuroses. X-ray examination showed normal density of the bone plates. No complication was noted. The bone plate can be used in postoperative cranioplasty.
