In Reply Much literature has been published for several decades regarding injection sites in and around the facial area for cosmetic and medical reasons, which can result in vision loss or worse consequences.1- 5 The glabella has been reported several times and is in close proximity to the main arterial supplies, the supratrochlear and supraorbital arteries, which, as Kim and colleagues correctly identified, are the likely arteries inadvertently cannulated during the procedure. Our series, however, was focused on purely higher forehead injection, which, owing to the more distal location, may provide a false sense of security to physicians doing the injection as the branched arteries are smaller in these regions. We wanted to ensure that “forehead” was cited as a distinct entity, not “roughly described” and included in the glabellar region.
