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

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Anatomy-based Rejuvenation

Background:

• Traditional neck rejuvenation techniques overlook intrinsic anatomical asymmetries like mandibular-cervical asymmetry and digastric insertions.
• These factors significantly influence submental contour and necessitate a three-dimensional, anatomy-based correction approach.

Purpose of the Study:

• To evaluate the outcomes of a 3D neck lift technique for isolated neck rejuvenation.
• To assess the technique's efficacy in addressing anatomical asymmetries and improving cervicomental angle definition.

Main Methods:

• A retrospective study of 177 patients undergoing the 3D neck lift, a technique combining triangular platysma myectomy, digastric resection, and subplatysmal fat control.
• Adjuncts like platelet-rich plasma (PRP) or bipolar radiofrequency were used in advanced cases (stages III-IV).
• Outcomes were evaluated based on complications, morphological changes, and patient satisfaction.

Main Results:

• 92% of patients presented with mandibular asymmetry.
• Excellent or good cervicomental angle definition was achieved in 98% of cases, with 96% patient satisfaction.
• Complications were minimal, including transient marginal mandibular paresis and seromas, all resolved with simple aspiration.

Conclusions:

• The 3D neck lift provides a personalized, single-incision solution for submental rejuvenation by integrating natural asymmetries and anatomical corrections.
• The technique restores a stable cervicomental angle with low morbidity, offering a reliable, scar-sparing alternative.
• Adjunct therapies like PRP or radiofrequency can enhance results in advanced cases but are not essential for the core technique.
