Objectives: Recently, the importance on the facial anatomy has been reconsidered as the interest on the facial aesthetics is increasing. Through this lecture, I would like to show the 3-dimensional layered facial anatomy and the individual variations of the face related to threading procedure for the safe and efficient clinical applications.
Introduction: Sagging is also a major aging phenomenon for which surgical corrections have been considered as the only treatment option. However, thread lifting is now widely performed as an alternative procedure for improving facial sagging and relocating facial fat. The target layer of the face for thread lifting should be the superficial fat in order to reduce the likelihood of complications and obtain optimal outcomes. For these reasons, it is crucial to understand the regional topography of the skin, facial superficial fat and underlying fascia structures when performing minimally invasive procedures.
Materials / method: Thirty fixed Korean and Thai cadavers (male: 17, female: 13) were used. The depths of the skin and superficial fat were measured using a three dimensional (3D) structured-light scanner. Facial images of both undissected and removed skin and superficial fat were taken with the 3D scanner.
Results: Threads for vertical lifting are usually inserted in the temple region. In the temple region, the superficial facial fat tended to become thicker from the upper to the lower part, and was slightly thinner in the anterior than the posterior temple region. It is thought to be due to the lack of volume in the upper anterior area in most aged persons.
Conclusion: I would like to introduce the facial US anatomical findings based on in-depth morphological studies using an US imaging that were previously impossible to obtain. In addition, the static and dynamic facial US imaging and the individual variations of the face related to thread lifting procedures for the safe and efficient clinical applications will be demonstrated. We strongly believe that only the US would help clinicians to detect the anatomical variations of the muscles and vessels for satisfying procedural results.
