title: [Clinal analysis of 202 nasal bone fractures cases].
abstract: OBJECTIVE
  To evaluate the age, sex, etiology, diagnosis and treatment time of nasal bone fractures.
  
  
  METHODS
  Clinical data of 202 cases with nasal bone fractures treated in the hospital were retrospectively analysed.
  
  
  RESULTS
  A total of 202 cases,163 men (80. 7%) and 39 women (19. 3%). Fifty-two patients had a relationship with alcohol consumption, and all of them were males. The most frequent reasons of the injury were fight 46. 5% (94 cases) followed by falling-down 21. 3% (43 cases), traffic accidents 19. 3% (39 cases), works related 6. 5% (13 cases), sport injuries 5. 9% (12 cases) and others 0. 5% (1 cases). Patients distribution in seasons were: spring 54 cases (26.7%), summer 42 cases (20.8%), autumn 58 cases (28.7%), winter 48 cases (23. 8%). Diagnosis of nasal bone fractures were made positively by x-ray films in 79. 7% of cases, but 100% by CT. Positive predictive value of CT was superior to that of X-ray films in the diagnosis of nasal bone fracture.
  
  
  CONCLUSIONS
  High morbidity of nasal bone fracture was seen in the age group of 20-29 years, and predominantly in male. Fight was found to be the main etiologic factor. We think that CT is necessary for diagnosing nasal bone fracture.
