[Diagnosis and restitution of nasal bone fracture]
Objective:
To discuss accurate methods of diagnosis and restitution for nasal bone fracture.
Method:
280 cases of nasal trauma were examined by lateral x-ray test (horizontal CT-scan was also used in 76 cases of these patients).
Result:
220 cases were found with bilateral fracture of nasal bone. Unilateral fracture, simple fracture of frontal process of maxilla, compound fracture of nasal bone and frontal process of maxilla, compound fracture of nasal bone, maxilla and perpendicular plate of ethmoid bone were seen in 12, 15, 30 and 3 cases respectively.
Conclusion:
X-ray examination can only find bilateral fracture of nasal bone, but CT-scan can demonstrate unilateral fracture, fracture of frontal process of maxilla and fracture of perpendicular plate of ethmoid bone. Restitution with pincers is still a routine therapeutic method for nasal bone fracture at present, and nasal septal reconstruction is necessary when both nasal bone and perpendicular plate of ethmoid bone were involved. But for those patients with high-position compound fracture, restitution by directly visual operation through lip-dental-gum approach is the best choice.
