Answer:
The correct answer is C, Septal hematoma.A septal hematoma is considered an emergency that requires urgent treatment.The Kiesselbach plexus is a region of anastomoses among the sphenopalatine, anterior ethmoidal, and superior labial arteries in the nasal septum that is a common site of epistaxis (nosebleeds).Trauma to the Kiesselbach plexus can cause epistaxis, which can be treated with cautery, packing, or other methods.A closed nasal fracture or a deviated septum are not considered emergencies requiring urgent treatment.
