Abstract            :  Background: Filler injections are frequently associated with vascular complications.Objectives: To investigate the course and location of the middle-midface perforators to establish safe cannulaentry sites for filler injections.Methods: The middle-midface was studied using 28 hemiface specimens from soft embalmed Thai cadavers atthe Faculty of Medicine, Chulalongkorn University. Investigations were performed following injection of red latex.Results: Middle-midface perforators were classified into 3 groups according to their origin. These perforatorsoriginated from the buccal branch of the facial artery (57%); the parotid artery (25%); or directly from the facialartery (18%). The distance between the buccal artery perforator (level with the upper alar crease) and the lateralcanthal (Y axis) line was 2.6 (SD 6.0) mm and Frankfort’s horizontal (X axis) lines was −16.4 (5.4) mm. The distancebetween the parotid artery perforator and the lateral canthal vertical line was 4.2 (10.8) mm and Frankfort’shorizontal line was −13.9 (3.4) mm. The distance between the facial artery perforator and the lateral canthal verticalline was 11.2 (10.8) and Frankfort’s horizontal line was –16.0 (5.3) mm.Conclusions: A single long perforator was identified along the lateral canthal vertical line. This most commonlyoriginated from the buccal branch emerging from the facial artery. Therefore, we recommend a cannula be insertedat the Beut site 2 cm inferolateral to the lateral canthus. This injection site is recommended as a safe to avoidinjury to the middle-midface perforato
