摘要

Abstract

<正> In order to provide an experimental foundation and pathological base for earlyreconstruction of maxillofacial tissues defects after firearms wound using microsurgicalmethods

an experiment

was made to study the microvascular pathological changesthrough light and electron microscopy observation.In the experiment we found somepathological changes of small vessels in wounded region

such as mierothrombi forma-tion

endothelial loss

internal elastic membrane break and some degenerations

necrosis within endothelial and smooth muscle cells of vessel.The nearer the woundededge was

the more evident injury was.The microvascular injurous range was 3 cm dis-tant from wounded edge

which recovered in 7 days later after wounding.The experi-ment indicated that if we used the vascularized free tissue transfer to repair defects ofmaxillofacial firearms wounds

the pedicles of flap should be anastomosed to distant re-cipient vesseles which could be chosen beyond 3 cm from wounded edge.Thereconstructive operation should be done 7 days later after wound.
