comparison of the frequency of old septal deviation in patients with and without traumatic nasal bone fracture

investigating the frequency of traumatic nasal bone fracture in patients with and without old septal deviation and possible deviation. prospective study of 105 patients with nose trauma conducted and cases were divided into two groups: a study group 35 patients with nasal fracture and a control group of 70 patients without nasal fracture. diagnosis of septal condition was made by anterior rhinos copy and endoscopy using manipulation of septum. 31 (89%) of the patients with nasal fracture after trauma were diagnosed with old septal deviation. in comparison, only 39 (34%) of patients in the control group were diagnosed with old septal deviation. in comparison, only 39 (54%) of patients in the control group were diagnosed with old septal deviation. existing old septal deviation significantly increases the risk of traumatic nasal bone fracture.
