An Anatomical Guide to the Terminal Facial Artery: Lumen Diameter and Associated Anatomy Relevant to Dermatologic Procedures.

Background: Dermal filler injection in the vicinity of the terminal facial artery (FA) can lead to vascular compromise with devastating consequences, including tissue necrosis, blindness, and stroke.

Objective: The purpose of this study was to examine lumen diameter and other anatomical features of the terminal FA relevant to dermal filler injection.

Materials And Methods: Eighteen embalmed adult cadavers were dissected along the distribution of the terminal FA.

Lumen Diameter and Associated Anatomy of the Superior Labial Artery With a Clinical Application to Dermal Filler Injection.

Background: Vascular compromise and subsequent tissue necrosis is a rare but disfiguring complication of dermal filler injection that frequently occurs in regions of the lip and nasolabial fold supplied by the superior labial artery (SLA).

Objective: The purpose of this study was to examine lumen diameter and other anatomical features of the SLA relevant to dermal filler injection in the clinical setting.

Materials And Methods: Eighteen adult cadavers were dissected.
