Waterfall deformity means the breast tissue has dropped off the implant while the implant stays relatively high, often with the nipple/areola sitting low on the breast mound. In your photos, there is some asymmetry and the right lower-pole/areola relationship should be checked, but I would not diagnose a true waterfall deformity from photos alone. Since your surgery was in November 2024, the result is likely fairly mature. If the shape is stable and you like the overall look, observation may be reasonable. If the right breast tissue is sliding over a higher implant or the nipple position bothers you, correction depends on the cause and may involve pocket adjustment, implant position change, or a small lift/tightening procedure after an in-person exam.
