Ultrasonographic Anatomical Changes in the Nasal Vasculature after Rhinoplasty: Analysis of a Series of Cases

It is known that surgical procedures can change the vascularization of the face, and these changes can be related in the course and depth of vessels, increasing the risk for complications with injectable products. The goal of this work is to objectively demonstrate the course and variation of these vascular structures through Doppler ultra-sonographic monitoring. In this research 9 patients were studied, of which 7 completed the study. The presurgical ultrasound study detected anatomical variations like agenesy of the angular artery and dorsal nasal artery in 11.12% of tha patients. The post surgical evaluation detected 85.71% of vascular changes mainly in the nasal arteries. This findings confirm the importance of practicing ultrasonographis evaluation in patients with rhinoplasty, previous to practicing new filler injections in the face.
