Scarless Rib Reshaping: Comparison of Straight and Oblique Approaches in Terms of Efficacy and Recurrence.

Background: Perceptions of physical beauty vary across cultures and are shaped by evolving social norms and media influences. In this context, body contouring procedures have gained increasing popularity; however, conventional approaches such as liposuction may be limited in patients with a wider thoracic framework. Consequently, waist-narrowing procedures, including rib remodeling techniques, have emerged as adjunctive or alternative strategies to enhance waist definition. Recent advances in rib remodeling aim to achieve a reduction in waist circumference while promoting an "hourglass" silhouette with minimal visible scarring. Accordingly, the present study aims to compare straight and oblique rib-remodeling techniques in terms of waist circumference reduction and recurrence over time. Methods: A retrospective cohort study included 240 female patients: 100 underwent the straight approach and 140, the oblique approach. Preoperative variables included age, weight, body mass index, and abdominal circumference. Postoperative abdominal circumference was evaluated immediately and at 3, 6, and 12 months. Recurrence was defined as an increase in abdominal circumference during follow-up. Group differences were analyzed using the z-test. Results: Baseline characteristics were comparable between groups. The oblique approach was associated with a shorter operative time ( Conclusions: The oblique rib-remodeling technique provides more durable waist circumference reduction with lower recurrence rates, supporting its role as an effective body contouring option.
