Measurement of Flap Blood Flow by Laser Doppler Velocimeter in Oral Surgery

Recently the laser doppler velocimeter has been developped as aids in evaluation of microcircuratory flow in a variety of human tissue. We have used this instrument to measure viability of the flaps which were transplanted to the reconstruction of maxillo-facial region.The blood circulation of D-P flaps and Abbe flap were measured by laser doppler verocimeter. The analog data of the blood circulation was analyzed by using personal computer. The software for data analysis was developped by ourselves.The laser doppler verocimeter is a non-invasive instrument capable of instantaneous and continuous evalation of local flow in tissue microcirculation. It is fit to monitor viability of flaps used oral and maxillo-facial surgery.
