The nose is the most prominent part of the face and is vulnerable to external forces. Nasal bone fracture is a common trauma in otolaryngology, accounting for about 50% of trauma diseases in otolaryngology. Fracture of nasal bone will affect facial appearance and nasal ventilation function. Nasal bone fracture can occur alone, and in severe cases, it can be combined with nasal septum fracture, cartilage dislocation, maxillary frontal process, sinus, orbital wall, skull base and other injuries, resulting in abnormal structure and function of the corresponding parts.

(1) Abnormal external nose caused by nasal bone fracture.

(2) The external nose and its surrounding tissues are swollen.

(3) Nose bleeding can occur when nasal mucosa and blood vessels are injured, and the amount varies.

(4) Nasal congestion, nasal mucosal swelling, deviation of nasal septum and hematoma of nasal septum can all lead to it.

(5) The outflow of nasal water sample indicates cerebrospinal fluid leakage.

(6) The vision is decreased, and the orbital wall and optic nerve of diplopia are damaged.

(7) Headache, loss of consciousness and possible intracranial injury.
