The way to reinforce or strengthen nasal cartilage support is cartilage grafts and/or suturing cartilages together. There are different types of cartilage weakness in the nose. The ligaments between the tip cartilages and the septum could be disrupted. The tip cartilages can be weak and collapse with inspiration. The upper side and tip cartilages may not move together normally during respiration. All of these are examples of weak nasal cartilage but they are treated differently. Even with static photos it may not be possible to know what procedure would be best. That requires a face to face examination with observation of changes in nasal structure while breathing.
