How to distinguish nasal bone fracture from maxillary frontal process fracture by CR film or CT film

The fracture of nasal bone is mainly taken by lateral X-ray film of nasal bone. When nasal septum hematoma is suspected, it can be diagnosed by puncture and aspiration. The diagnosis of nasal bone fracture is mainly based on the history of trauma, clinical characteristics and local examination. Displacement deformity can be seen when the nasal bone fracture is not swollen locally, and the fracture site can be found by asking. After obvious swelling, the fracture displacement deformity can be concealed, and the diagnosis can only be made by carefully examining the X-ray films inside and outside the nose and the positive side of the nasal bone.

Frontal process fracture of maxilla

CT examination: The fracture of nasal bone and maxillary frontal process should take coronal scanning as the main means; If combined with axial scanning, the diagnosis will be more comprehensive, the fracture and nasomaxillary suture can be clearly observed in coronal position, and the fracture dislocation and nasomaxillary suture fracture can be observed more accurately in axial position.

Comprehensive judgment is made mainly by coronal scanning and axial scanning. ...
