3D Neck Lift: A Dynamic Approach to Submental Anatomy.

ABSTRACT:

Background

Traditional neck rejuvenation-liposuction, platysmaplasty, and skin redraping-overlooks intrinsic mandibular-cervical asymmetry,digastric insertions, platysmal discontinuity, submandibular gland descent, and age-related hyoid retrodisplacement. These influence submental contour and require a tridimensional, anatomy-based correction.

Methods

A retrospective study of 177 patients (99 women, 78 men; mean age 59 y, range 26-78 y) undergoing isolated neck rejuvenation (2003-2024) assessed outcomes of the 3D neck lift, which has been used since 2018 in Knize stage II-III and stage IV cases. The technique combines a triangular platysma myectomy forming a stabilizing neo-floor, partial digastric resection, and subplatysmal fat control, with platelet-rich plasma (PRP) (sta
