Background and Objectives : There are many classifications of nasal bone fracture. The majorities of fractures are according to direction and degree of fracture. But no paper has reported the clinical application of classification of nasal bone fracture by CT (Computed Tomography) scans. The purpose of this study is to evaluate the practical effectiveness of new classification of nasal bone fracture according to CT scan. Materials and Methods :We studied 121 patients with nasal bone fracture which was diagnosed with facial CT scans. Type I fracture is unilateral thin bone fracture. Type II fracture is bilateral thin bone fracture. Type III fracture is bilateral fracture including thin and thick bone. Type IV fracture includes the neighboring bone fractures. Each types are subdivided into ‘s’ and ‘o’ according to presence and absence of septal fracture. Doctor’s and patient’s satisfactions were investigated after minimal 6 months later by visual analogue scale. All results were statistically confirmed. Results :Patient’s and doctor’s satisfactions were statistically lower in severe fractures and septal fractures. Satisfactions of open reduction was high than closed reduction in Type III fractures. Conclusion :New classification systems help to decide surgical procedures and predict operative results.
