Objectives: To assess long-term aesthetic outcomes of silicone suspension threads in jawline and neck contouring, with specific focus on cervicomental angle (CMA) improvement, reduction of submandibular gland visibility, and the durability of these effects over time. The presentation aims to correlate sustained aesthetic changes with surgical planning and indication. Introduction: Jawline and neck definition depend on stable support of deep and superficial structures. Silicone suspension threads have been used to address laxity and contour loss by providing long-term mechanical reinforcement. While short-term improvement is commonly reported, the persistence of CMA correction and gland camouflage remains clinically more relevant and less frequently discussed. Materials / method: Patients treated with silicone suspension threads for jawline and neck contouring over an eight-year period were retrospectively reviewed. Analysis included indication, vector orientation, anchoring technique, tissue quality, and anatomical relationship to submandibular gland position. Outcomes were evaluated through standardized clinical follow-up focusing on contour stability. Results: Consistent improvement in CMA and decreased visibility of the submandibular gland were observed when correct indication and stable anchoring were achieved. These aesthetic gains were maintained over time in appropriately selected patients. Diminished or lost effects were predominantly linked to anatomical limitations or technique-related factors rather than material failure. Conclusion: Silicone suspension threads can achieve durable improvement in jawline and neck aesthetics, including CMA definition and submandibular gland camouflage. Long-term success depends on precise indication, anatomical planning, and method of application. When these factors align, aesthetic outcomes are not only improved but sustainably preserved.
