Objectives: To assess the clinical efficacy , and patient-reported outcomes of a standardized protocol utilizing subcutaneous hyaluronic acid filler for aesthetic enhancement of shoulder contour in individuals with hypotrophic or ptotic shoulder profiles. Beyond physical appearance, shoulder asymmetry or drooping—particularly when exposed in off-shoulder or sleeveless garments—has been reported by patients as a source of psychological distress and diminished self-confidence .This study aims to provide a minimally invasive corrective solution addressing both aesthetic and psychosocial concerns. Introduction: The shoulder line significantly contributes to upper body aesthetics and perceived body harmony, particularly in exposed garments. While surgical interventions have traditionally addressed shoulder contour deformities, they often entail invasiveness and recovery time. Over recent years, an increasing number of patients have sought non-surgical correction for shoulder drooping or asymmetry. Our clinical experience demonstrates that injectable fillers can effectively restore contour and improve patient confidence without downtime. Materials / method: In this presentation, trapezius angle assessment was performed via standardized photography and goniometric measurement between the clavicular head and acromial process. After marking the muscle border and delineating the sloping vector, a 22 G cannula delivered high-cohesivity hyaluronic acid filler in a layered retrograde fan pattern across subcutaneous entry points. Total volume per side ranged from10to15 mL. Post-injection gentle molding and clinical reassessment ensured precise angle correction and bilateral symmetry. Assessments were repeated immediately and at 12-week follow-up. Results: All 30 participants completed the 12-week follow-up without major adverse events. Quantitative analysis showed a mean improvement in trapezius angle from a pre-treatment average of 33° ± 4.° to a post-treatment range within the normative aesthetic range of 15–25°, maintained at follow-up. After 6 month follow up we recognized a consistent enhancement in shoulder projection and contour symmetry. Patient-reported outcomes revealed 100% satisfaction, with no cases of palpable nodules, vascular events, or prolonged edema. Conclusion: Hyaluronic acid shoulder augmentation provides a safe, effective, and minimally invasive solution to restore shoulder symmetry, enhance body image, and increase self-confidence—particularly in garment selection and public appearance. Adverse events are minimal (transient ecchymosis resolving within days). Success hinges on a rigorous, anatomy-guided protocol: low-pressure, subcutaneous filler placement at the correct depth, with careful respect for dermal tension vectors and local vascular anatomy to prevent ischemic & other complications.
