Thank you very much for your query. First of all I must clarify that fractures of nasal bone and the bone around the eye are ideally treated by facio-maxilliary surgeons. These bones are not normally treated in plaster and therefore, no plaster mobilization is required. Healing of a fracture is always a natural process and it cannot be hasten by any medicines.The decision regarding your case will have to be done in consultation with a facio-maxilliary surgeon. In some departments this work is done by plastic surgeons. Either way you may need to have good quality X-rays to decide whether any intervention is required for your fracture. If the fracture is in alignment nothing may be required.
