Exposure of cartilage in the nasal septum or nasal cavity is one of the symptoms of nasal bone fracture. Nasal bone fracture is often caused by trauma, and clinically there are lacerations of the nasal cavity and nosebleeds, which can be closed or open. It can be closed or open. It is also often accompanied by other facial bone or skull base fractures. So how to prevent and care for nasal septum or nasal cavity cartilage exposure? 1, pay attention to rest, avoid direct head wind. 2, sports, wear glasses, temporarily removed. 3, because of the nasal breathing is not good, often with the help of oral breathing, so it is more appropriate to keep the air fresh and moist. 4.If you suffer from cough and allergic rhinitis, try to control coughing and sneezing. 5, diet, fracture early, due to severe swelling and pain, fever and loss of appetite, so the diet should not be excessive, dishes should not be nourishing. In the later stage, the swelling and pain have been gradually relieved, and the appetite gradually returns to normal, so the nutrition can be strengthened to promote healing. Nasal trauma resulting in nasal fracture within 24 hours should be cold compresses, cold wet towels or ice packs placed on the nose, need to be replaced at any time, the purpose is to promote vasoconstriction, reduce subcutaneous hemorrhage, more than 24 hours, subcutaneous hemorrhage gradually static, this time you can do hot compresses, with hot wet towels, but the temperature should not be too hot, 60 ℃ or so. The purpose of hot compress is to promote vasodilation, absorb blood stasis and swelling, reduce pain and promote recovery. Do not rub the nose after the injury, so as not to aggravate the trauma and fracture. Keep the sick child quiet and the airway open. Fracture repositioners should go to the hospital for rechecking on time. Clinical work often found that many patients with bone fracture in order to bone growth faster, often and bone soup, and even must drink bone soup every day, as a panacea application. This may be by some common idea “eat what make up what” point of view misleading. In addition, some people think that bone broth calcium. Also, some orthopedic surgeons suggest that eating some bone broth will promote bone healing. But the highest content of bone broth is phosphorus, not calcium. High phosphorus intake will greatly affect the body’s absorption of calcium, so, bone broth drink too much not only does not make up for calcium will affect the absorption of calcium, is not conducive to fracture healing. In addition, the fat content in bone broth is high, drinking bone broth may mainly increase weight rather than supplemental nutrition.
