Revealing the Three-Dimensional Complexity of Facial Anatomy Through Micro-Computed Tomography

Area of Science:

• Medical Imaging
• Anatomical Sciences
• Aesthetic Medicine

Background:

• Micro-computed tomography (micro-CT) provides high-resolution 3D imaging of facial anatomy (4-10 μm resolution).
• Micro-CT is limited to ex vivo specimens, preventing dynamic or functional assessments.

Purpose of the Study:

• To emphasize the value of high-frequency ultrasound for facial anatomical assessment and procedural guidance in clinical settings.
• To compare the capabilities of micro-CT and ultrasound in aesthetic medicine.

Main Methods:

• Discussed limitations of micro-CT for dynamic imaging.
• Explored clinical advantages of ultrasound, including Doppler and real-time soft tissue imaging.

Main Results:

• High-frequency ultrasound (30-70 μm resolution) allows in vivo dynamic imaging of vascular flow, muscle activity, and filler placement.
• Ultrasound is non-invasive, repeatable, and suitable for point-of-care aesthetic procedures.
• Finger-mounted ultrasound devices and Doppler integration enhance procedural safety.

Conclusions:

• Micro-CT is optimal for high-resolution anatomical research.
• Ultrasound provides essential functional, real-time assessment for safe clinical practice.
• Both modalities complement each other for anatomical understanding and patient care in aesthetic medicine.
