The aim of this study was to test a new experimental design of venous system arterialization on the rabbit ear arterialized venous flap (AVF) model. Total number of 10 "Big Chinchila" rabbits were divided in two experimental groups. On both ears of the five rabbits (Group 1) we have performed our original method of venous system arterialization with microsurgical arterialization of the central artery and vein with the preservation of central and peripheral vascular perfusion; at both ears of five rabbits (Group 2) we have performed AVF according to Byan et al., (1995). Vital AVF surface and necrosis percentage were determined in both experimental groups at day 1 and day 14 and results were compared using Student t-test. The results of our experiment indicate that our new experimental design of the AVF on rabbit ear model has better hemodynamic conditions, improves AVF survival and gives significantly bigger vital flap surface at 14 days after venous system arterialization

Vascularized osteocutaneous scapular flaps belong into the most convenient ones in reconstruction of mandibular defects followed by massive loss of adjacent skin and mucous membrane due to its vascular supply, bulkiness, suitability and mobility of cutaneous component of the flap. In seven wounded patients such defects of the mandible and adjacent soft tissues after war wounding have been reconstructed at the Clinic for Maxillofacial Surgery of the Military Medical Academy - Belgrade during the six years period with vascularized osteocutaneous scapular grafts. Here we present localization and structure of the defect, features of harvested compound graft, the procedure of reestablishment of mandibular continuity, immediate and late complications during the consolidation period, as well as the analysis of the success rate.
