Etiology and Epidemiology of Nasal Bone Fractures in Patients Referred to the Otorhinolaryngology Section, 2019.

 One of the most observed diseases in the otorhinolaryngology emergency, compared with the other facial fractures, is related to nasal bone fractures (NBFs). The peak of incidence is seen in the age group ranging from 11 to 30 years old.  The present evaluation was devoted to the etiology and epidemiological study of NBFs.  In the present cross-sectional study, 376 patients with NBF were evaluated. The necessary information such as gender, age, education, job, causes of NBF, and clinical symptoms of patients have been recorded on the checklist.  The study revealed that 76.9% of the patients were male and 23.1% were female; 37.5% of all patients were self-employed, and most of them were from urban areas. Traffic accident (26.6%) and falling (25.5%) were the main reasons for NBF. The most common clinical symptoms for NBF were tenderness (96%;  = 361), nasal swelling (90.4%;  = 340), and deformity (89.4%;  = 336).  The results showed that the incidence of NBFs in young men without higher education level and self-employed were high which can be related to the traffic accidents and fights. Also, falls, beatings and accidental hit are the most common causes of NBFs among women. Therefore, to decrease the incidence of otorhinolaryngology trauma, training about the general life skill and providing awareness about using personal safety equipment and measures should be increased at the future.
