It is not uncommon to try to improve the form and/or function of a nose during rhinoplasty by using grafts. Cartilage grafts are sometimes used, and the ear cartilage is sometimes the source. However when a placed graft is overly visible or creating a new problem, these sometimes must be removed and an alternate technique used.
Rhinoplasty is one of the most technically demanding surgery.There is no way to give appropriate advise from a picture showing the nose only.In analyzing the nose one needs an in person examination, pictures of the whole face in frontal views profiles and 3/4 views. Noses should be in harmony with the entire face
looking at your photo I would remove the graft and place a fascia graft in its place. It also appears your lower lateral cartigages are wide.I would revise that as well.
