Relapsing polychondritis is a rare degenerative disease characterized by recurrent inflammation of the cartilage in the body. Deterioration of the cartilage may affect any site of the body where cartilage is present. Ears, larynx and trachea may become “floppy,” and the bridge of the nose can collapse into a “saddlenose” shape. The aortic heart valve may also be affected.
