Ultrasound Anatomy of the Dorsal Nasal Artery as it Relates to Liquid Rhinoplasty Procedures

Abstract

Nonsurgical rhinoplasty procedures using soft tissue fillers have gained popularity. With the increasing frequency of such procedures, the incidence of intra-arterial injection of soft tissue filler material and subsequent ischemia has also risen. This article analyzes the topographic anatomy of the dorsal nasal artery in the nasal soft tissue to potentially enhance patient safety in nonsurgical rhinoplasty procedures. The dorsal nasal artery shows a variable topographic course, especially in relationship to the procerus muscle. By understanding the topographic courses of the dorsal nasal artery, aesthetic practitioners may be able to perform nonsurgical rhinoplasty procedures with increased safety and efficacy.
