Study of 2,881 Nasal Bone Fractures using Multivariate Analysis.

This retrospective cohort study is aimed to provide a certain reference for the clinical prevention and treatment of nasal bone fracture, and further formulated a more perfect diagnosis and treatment plan. In detailed cases, 2881 patients with nasal bone fracture were recorded. Its general clinical data, cause of injury, fracture site, and fracture typing were collected through the database. All hospitalized patients admitted to the Ninth People's Hospital Affiliated to the School of Medicine of Shanghai Jiao Tong University with integrated medical records could be retrospectively included from June 2013 to July 2018 and comprehensively analyzed for their gender, age, fracture type and cause of injury. The sex ratio of nasal bone fracture was 2.44:1. The most patients with nasal bone fracture were 19-29 years old (35.6%). The injury rate of traffic accidents was the highest, 33.8%, followed by violent strikes, 24.1%. Statistical analysis showed that the number of patients with nasal bone combined with maxillary frontal bone fracture and type II nasal bone fracture was significantly higher than other fracture types. Logistic multiple regression analysis showed that the relative risk of nasal bone fracture in men was lower (odds ratio, OR = 0.807, P < .05), and the risk of nasal bone fracture decreased with age (OR = 0.978, P < .001). Compared with car accident injury, the relative risk of simple nasal bone fracture comes from violence, exercise or collision [OR = 1.244, P < .05; OR = 1.410, P < .05; OR = 1.453, P < .05]). Given these findings, it's evident that nasal bone fractures exhibit distinct patterns based on individual characteristics, causes of trauma, and injury site, and relevant strategy research should be conducted.
