Composite grafts through rhinoplasty principles can help. What this is means is that you can take a graft from your ear or other area which will include a composite of skin, cartilage and intervening tissue that can be implanted within the nostril to enlarge the aperture. Also different tissue advancing techniques and transposition of close tissue from the mouth or around the nose can be done to also enlarge the nostril.
