title: Facial Artery Myomucosal Flap, Pedicled Solely on the Facial Artery: Experimental Design Study on Survival.
abstract: BACKGROUND
  Facial artery myomucosal flap pedicled solely on skeletonized facial artery has been reported in the literature. Venous drainage of this modified flap is doubtful so an animal study was designed to verify the survival of this flap.
  
  
  METHODS
  Three healthy adult male mongrel dogs with weight between 20 to 30 kg were enrolled in this study. Split mouth technique was used in this experiment. Flap paddle was designed over the facial artery and vein. Facial vein was ligated and divided. Flap was returned to the original site and sutured (experimental group). In the other side, flap was harvested but returned to the original position without disturbing the vascular pedicle (positive control).
  
  
  RESULTS
  All buccal mucosa island flaps with preserved facial artery and vein were survived, whereas all the flaps with the occlusion of facial vein undergo necrosis.
  
  
  CONCLUSIONS
  Island FAMM flap, pedicled only on skeletonized facial artery, is not biologically accepted for clinical usage.
