Rhinoplasty is considered permanent. Once bone and cartilage are reshaped and healed, the new framework stays. Unlike non-surgical rhinoplasty with dermal fillers, which lasts roughly 9 to 18 months, surgical results do not wear off.
That said, results settle rather than stay frozen. The splint comes off in about a week, most visible swelling fades by six weeks, and refinement continues for 12 to 18 months. Thick-skinned and revision noses can take up to two years to show final shape.
Your nose will still age with the rest of your face. Skin thins, cartilage weakens, and the tip may drop slightly over decades. Well-executed structural rhinoplasty with proper tip support is designed to resist that drooping far better than older reduction-only techniques.
