Visualization techniques of the facial arteries

Area of Science:

• Medical Imaging
• Vascular Anatomy
• Facial Surgery

Background:

• Facial vascular anatomy exhibits significant variation.
• Increasing filler-associated complications necessitate safer visualization methods.
• Current imaging techniques have limitations in depicting complete facial arterial networks.

Purpose of the Study:

• To review existing medical imaging methods for facial arteries.
• To evaluate a recently developed MRA protocol for facial vascular visualization.
• To identify a harmless method for visualizing individual facial arterial anatomy.

Main Methods:

• Comprehensive literature review of facial artery imaging over the last 20 years, with emphasis on the last 5 years.
• Analysis of various medical imaging modalities.
• Evaluation of a specific MRA (magnetic resonance angiography) protocol.

Main Results:

• Ultrasound (US) and MRA are currently the only harmless visualization methods for facial arteries.
• US can identify individual vessels but not the complete arterial network.
• A combination of IR "heat enhancement" and MRA 3D-TOF shows promise for comprehensive, risk-free facial artery visualization.

Conclusions:

• A novel combination of IR "heat enhancement" and MRA 3D-TOF may be the sole current method for visualizing numerous facial arteries.
• This technique offers a non-invasive, radiation-free, and contrast-free approach.
• It addresses the need for detailed, safe visualization of facial vascular anatomy.
