Background: Hybrid breast augmentation, a combination of silicone implants and autologous fat grafting, is an innovative approach aimed at achieving natural aesthetics. This study evaluates its impact on reducing intermammary distance and improving cleavage aesthetics. Methods: A retrospective analysis was conducted on 131 female patients (30–55 years) who underwent hybrid breast augmentation between January 2021 and September 2024. The procedure involved subfascial silicone implant placement and fat grafting to the superomedial breast quadrant. Fat was harvested from the abdominal or thigh areas. Outcomes included cleavage distance measurements and patient satisfaction assessed via Breast-Q© scores. Results: Postoperative cleavage distance decreased significantly (mean reduction from 9.5 ± 1.23 cm to 4.74 ± 0.48 cm, p < 0.0001). Implant sizes ranged from 230 cc to 320 cc (mean 271.64 ± 24.2 cc), while fat grafting volumes ranged from 50 to 100 cc (mean 63.11 ± 11 cc). High patient satisfaction was reported, with 93.9% rating their experience as “very satisfied.” Minor complications (e.g., wide scars) were noted in only 3.1% of cases. Conclusion: Hybrid breast augmentation effectively reduces intermammary distance, enhances cleavage, and achieves high patient satisfaction with minimal complications. This method represents a reliable technique for improving breast aesthetics, warranting further exploration in diverse patient populations.
