Rhinoplasty is a surgery that modifies the appearance of the nose, improves breathing, or both. Rhinoplasty can change bone, cartilage, skin, or all three. Rhinoplasty can change the size, shape, or proportions of your nose. It may be done to repair deformities from an injury, correct a birth defect, or improve some breathing difficulties. When planning rhinoplasty, your surgeon will consider your other facial features, the skin on your nose, and what you would like to change.
