Anatomic Consideration and Lifting Technique in Mandible Border Line Lifting With Multidirectional Thread.

This review presents a comprehensive analysis of mandible borderline lifting, a minimally invasive procedure designed to enhance jawline definition using barbed threads. The technique addresses age-related tissue laxity along the mandibular border by utilizing the anatomic structure of the platysma-auricular ligament as an anchor point. Recent changes in facial morphology among Korean populations, coupled with increased orthodontic interventions, have shifted esthetic focus from chin projection enhancement to overall jawline definition, similar to Western esthetic preferences. The procedure involves careful thread insertion through cannulas along the mandibular septum, engaging both inner and outer aspects of the jawline margin. Special consideration is given to anatomic structures, particularly the marginal mandibular branch of the facial nerve and critical blood vessels near the antegonial notch. The technique employs multidirectional barbed threads, with gauge selection based on individual patient characteristics. This method effectively restores jawline definition while maintaining natural anatomic contours, resulting in a more youthful appearance.
