BackgroundFiller injections are frequently associated with vascular complications.ObjectivesTo investigate the course and location of the middle-midface perforators to establish safe cannula entry sites for filler injections.MethodsThe middle-midface was studied using 28 hemiface specimens from soft embalmed Thai cadavers at the Faculty of Medicine, Chulalongkorn University.
