Analysis Of Craniofacial Fractures In 621 Cases

Objective: To develop social related policies,to improve the cognition and prevention of craniomaxillofacial trauma,and to provide the basis for the construction of hospital trauma team.Materials and Method: Materials: 621 cases of craniomaxillofacial fractures were treated in the department of craniofacial surgery,ophthalmology,otorhinolaryngology,neurosurgery and plastic surgery in July 2015-August 2016,in Shanghai Ninth People's Hospital,Shanghai Jiaotong University School of Medicine.Method: The study was divided into three parts: Part ?: sex,age and site distribution of 621 cases of craniomaxillofacial fracture;Part ?: etiology of 621 cases of craniomaxillofacial fracture;Part ?: risk factors of craniofacial fracture in 621 cases.Statistical analysis was performed using SPSS 22.0 statistical software package,including independent t test and Logistic regression,with P <0.05 as statistically significant.Results: The male to female ratio in 621 cases of craniofacial fracture were 2.18: 1;the average age was 34.7 ± 15.5 years old,19 ~ 29 years old(28.3%)was the peak age of fracture;traffic accident was the most common cause of injury(49.0 %);Orbital fractures were observed in 319 cases(51.4%),with the highest incidence.The mean age of the patients with mandibular fractures was 31.45 ± 16.25,and the mean age of the fractures of the zygomatic arch was significantly higher than that of other parts(39.48 ± 14.66).Falling is the most common cause of injury in children(41.3%)and elderly patients(66.7%),while traffic accidents are the most common cause of injury at the age of 15 to 69 years old.The probability of multiple fractures due to fall from a height(88.6%)is significantly higher than that of other injuries,followed by traffic accidents(73.3%).Age,traffic accidents,fall from a height,sports-related injuries and violence-related injuries are risk factors for orbital fractures.Sports-related injuries,traffic accidents and age are risk factors for zygomatic fracture.Fall from a height,traffic accidents and age are risk factors for maxillary fractures.Fall from a height,ground-level fall,traffic accidents,work injuries and violence-related injuries are risk factors for mandibular fractures,age is a protective factor for mandibular fractures.Conclusion: The number and location of fractures are related to age,the cause of injury,the mechanical properties and the anatomical structure of the corresponding parts.Establishing a sound traffic accident treatment system and related laws,strengthening the safety awareness is an urgent need to solve the problem.
