Anatomical layer analysis for safe thread insertion using micro-CT and ultrasonography: enhancing precision in facial...

Area of Science:

• Anatomy
• Facial Rejuvenation
• Aesthetic Medicine

Background:

• Thread lifting is a less invasive alternative to facelift surgery for facial rejuvenation.
• Optimal insertion layers for lateral facial thread lifting remain debated.
• Understanding lateral facial anatomy, including the superficial musculoaponeurotic system and facial nerve, is crucial for safe thread placement.

Purpose of the Study:

• To investigate the anatomy of the lateral face, focusing on the superficial musculoaponeurotic system and facial nerve.
• To evaluate the safety of thread insertion into the lateral facial area.

Main Methods:

• Eight fresh cadavers were utilized for anatomical study.
• Threads were inserted in the lateral face via a single temple entry point.
• Micro-computed tomography and ultrasonography were employed to assess safety and anatomical accuracy.

Main Results:

• Successful thread insertion was achieved in the correct anatomical layer, superficial to the superficial musculoaponeurotic system.
• No damage to critical structures like vessels, nerves, or muscles was observed.
• The imaging modalities confirmed the safety and precision of the insertion technique.

Conclusions:

• Insertion of threads into the superficial layer of the superficial musculoaponeurotic system is an anatomically advantageous approach for lateral facial lifting.
• This technique offers a promising method for effective facial rejuvenation with reduced risk of complications.
• The findings support optimizing thread-lifting procedures for enhanced safety and aesthetic outcomes.
