Anatomical Considerations and Technique for Nasolabial Fold Thread Lifting.

This review presents a comprehensive analysis of nasolabial fold classification and correction using thread-lifting techniques. Three distinct types of nasolabial folds are identified: those caused by paranasal volume deficiency, differential tissue laxity, and muscular insertions. The study emphasized the importance of Lore fascia as a key anatomical landmark and optimal adhesion point for thread placement, offering advantages over the traditional temporal approach. The technique uses a combination of bidirectional threads (Sihler Bi Lift) for tissue repositioning and volumizing threads (Sihler Volume) for fine line correction. Special consideration is given to the anatomical course of the facial artery and its branches, particularly in Asian populations, where more than 70% of people demonstrate medial crossing of the nasolabial fold. This comprehensive approach enables effective correction while minimizing complications.
