Anatomic-Based Diagnosis and Filler Injection Techniques: Chin Augmentation and Jawline Contouring.

Chin augmentation and jawline contouring have emerged as significant procedures in aesthetic medicine, addressing both structural and age-related changes in the lower face. This review explores anatomic-based diagnosis and filler injection techniques for these treatments. Ethnic variations in facial structure necessitate different approaches, with Western patients often seeking jawline definition, while Asian patients frequently require chin projection. The evolution of beauty standards and widespread orthodontic treatments have influenced treatment goals, emphasizing overall facial harmony. Successful outcomes rely on a thorough understanding of facial anatomy, including the complex interplay of muscles, fat layers, and soft tissue landmarks. The distinction between bony and soft tissue landmarks is crucial for optimal filler placement. Treatment techniques involve careful selection of filler consistency and injection depth, with high-viscosity fillers used for deep structural support and softer fillers for surface refinement. The use of cannulas in jawline treatments offers advantages in reducing complications and ensuring even distribution. Vascular anatomy knowledge is essential to avoid complications, particularly regarding the facial artery and its branches. Post-treatment management, including massage and follow-up assessments, is vital for achieving and maintaining desired results. This comprehensive approach ensures safe, effective, and aesthetically pleasing outcomes in chin and jawline enhancement procedures.
