13 year old collapsed bridge garlic nose can not be changed and treated, you can choose surgical treatment or filler treatment under the guidance of a doctor in adulthood. At 13 years old, the body is still in the stage of growth and development, and the nasal tissues are not yet fully developed, so the appearance of a collapsed nose and garlic nose at this time does not require special treatment. If the symptoms of a collapsed nose and garlic nose do not improve when the child reaches adulthood, or if they have a greater impact on his or her appearance, he or she can be treated with rhinoplasty or in the form of prosthetic implantation, autologous rib cartilage rhinoplasty, or hyaluronic acid injections. A child who develops a garlic nose in adulthood can also have his or her nose reduced by removing the medial border of the nose and the lateral border of the nose. Generally 13 year olds who present with a collapsed nose and garlic nose do not need to take steps to treat them. For patients who need plastic surgery, you can take your child for plastic surgery treatment as an adult.
