Measurement of blood by the 133~Xe clearance technique to grafts of amnion used in vestibuloplasty

摘要

The purpose of this study was to determine the blood supply to lyophilized amniotic membranes when used as graft material in vestibuloplasties. 133~Xe clearance technique was used to measure the blood flow to the grafs. A total of 20 patients had either Clark (10) or Kazanjian (10) vestibuloplasties. The blood flow was determined at 2-3 days preoperatively and at 10 and 30 days postoperatively.
