A C-shaped or crooked dorsum is usually a structural problem, so the treatment depends on where the deviation originates—septum, nasal bones, upper lateral cartilages, or several areas together. Spreader grafts are one way to support and straighten the middle vault, but they are not the only possible tool. Depending on the examination, a surgeon may use septal correction, asymmetric cartilage or bone reduction, controlled osteotomies, suture techniques, camouflage or onlay grafts, or other structural grafts. Sometimes a combination is needed to straighten the nose while maintaining an adequate airway. A photo or the phrase “C-shaped” is not enough to choose the operation. The surgeon should examine the external nose, septum, internal nasal valve, breathing, and skin/soft-tissue envelope, and review any prior surgery. If the deviation is mainly functional, preserving or rebuilding support is particularly important; aggressive reduction alone can worsen obstruction. I would obtain an in-person assessment from a surgeon experienced in functional and revision rhinoplasty. Ask what structure is causing the curve, how the airway will be protected, what graft material is proposed, and whether the goal is straightening, improved breathing, or both. Filler may camouflage a minor contour irregularity but does not straighten the underlying framework or reliably improve breathing.
