Anatomical Mapping of Nasal Arteries in Chilean Patients Using Doppler Ultrasound: Clinical Application for Injectables

Abstract

Background: This study aims to assess the anatomical positioning of critical nasal arteries in Chilean patients to improve the safety and efficacy of nonsurgical rhinoplasty procedures., Objectives: Using Doppler ultrasound, the study seeks to provide a precise vascular map that informs injection protocols and minimizes the risk of vascular complications, particularly in high-risk nasal regions., Methods: A cohort of 50 Chilean patients (ages 18-60, BMI 18.5-24.9 kg/m2) with no previous nasal procedures were evaluated. Doppler ultrasound was used to map the nasal vasculature, specifically targeting the dorsal nasal artery (DNA), radix, columella, and facial arteries in the piriform fossa. Key measurements included the depth of each artery relative to the periosteum and the skin surface. Descriptive statistics were used to calculate mean values and standard deviations for arterial distances, and comparative analyses were performed using the Student's t test or Mann-Whitney U test as appropriate, with a significance threshold set at P
