title: [Measurement of blood flow in labial and palatal mucoperiosteal flap after sectioning the greater palatine arteries and with a labial mucosal arcuate incision].
abstract: This article describes a study of determining blood flow of labial and palatal mucoperiosteal flap with radionuclide Xe-133 clearance technique before and after anterior maxillary osteotomies. The main purpose of the study was to investigate the dynamic change of blood flow. The greater palatine arteries were ligated. The studies show that compensative increasing of the blood flow of labial pedicle is seen after the operation, and that decreasing of the blood flow of palatal mucoperiosteal flap is temporary. It is suggested that the section of the greater palatine arteries is feasible. Xe-133 clearance technique is easy to operate and sensitive.
