Abstract: ［Abstract］ Objective〖HTSS〗〓To analyze the characteristics of nasal bone fracture in the pediatric population and to provide clinical basis for better prevention and treatment.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓We conducted a retrospective review on a series of 287 patients, 58(aged≤18 years) and 229(aged＞18 years), with nasal bone fracture who had been treated at our hospital. The following parameters were evaluated: sex, age, cause, monthly distribution and deviation of nasal septum. The children group were subdivided into preschool group(aged≤7 years), elementary school group(aged 8-14 years) and middle school group(aged 15-18 years).
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Compared to adults, nasal bone fracture was infrequent in pediatric population, and children′s nasal bone fractures were most occurred in middle school group. The numbers of man in each age group were higher than that of women as well as adults. Unlike the preschool group and elementary school group, the incidence of nasal bone fracture caused by violence was higher in middle school group and adult group. Nasal bone fractures in middle school group and Adult group were most commonly occurred in summer, and the other groups were lack of clear time distribution. Unlike the adult group, the deviation of nasal septum was less likely occurred in children.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Compared to adults, children′s nasal bone fracture has its own characteristics. Nasal bone fracture in the preschool group and elementary group chidren were lack of clear time distribution, but that in middle school group and ault group were most commonly occurred in june, september and december, and different ages have different characteristics. This study may be helpful in prevention and treatment.
