This systematic review explores the role of ultrasound-guided BoNT-A facial chemodenervation in evaluating anatomical accuracy, clinical efficacy, complications, and patient satisfaction. A comprehensive search of six databases through April 2025 identified studies assessing ultrasound-guided BoNT-A chemodenervation for facial indications. Sixteen studies were included, comprising randomized controlled trials, prospective cohorts, cadaveric trials, and anatomical mapping investigations. Data on injection accuracy, clinical outcomes, adverse events, and patient-reported measures were extracted. Risk of bias was assessed using validated tools. Ultrasound guidance improved injection accuracy, with cadaveric trials demonstrating up to 88% accuracy, while landmark-based techniques reported 50%. Clinical studies reported improvements in rhytid reduction, oral commissure elevation, neck relaxation, and facial symmetry. Adverse events were infrequent and mild. Patient satisfaction was consistently higher with ultrasound guidance. Anatomical studies identified muscle depth variation and vascular risk zones, supporting real-time sonographic targeting.
