Rib cartilage rhinoplasty involves the use of rib cartilage grafts to reshape or augment the nose. Lipolysis, which typically involves the injection of a solution to dissolve fat, is not typically used in the nose tip area. The primary concern with using lipolysis in the nose tip after rib cartilage rhinoplasty is the potential impact on the cartilage grafts. Lipolysis could potentially affect the blood supply and surrounding tissues, which may not be ideal for the stability of the cartilage grafts. It's essential to discuss your specific situation with a qualified surgeon who can assess the condition of your nose, the cartilage grafts, and the feasibility and safety of any additional procedures.
