Diplopia of pediatric orbital blowout fractures: a retrospective study of 83 XXXX classified by age groups.

@entity1 @entity892 @entity86 @entity174
Orbital blowout @entity174 are relatively rare in @entity1 under 18 years of age, but may lead to serious complications. We conducted this retrospective study to evaluate @entity892 , clinical characteristics, and postoperative results in cases of orbital blowout @entity174 in the pediatric population.Eighty-three @entity1 , all less than 18 years old, with orbital blowout @entity174 , were divided into 3 groups by age: 0 to 6 years old, 7 to 12 years old, and 13 to 18 years old. The cause of injury, @entity174 locations, @entity892 grades, ocular motility restrictions, enophthalmos, and postoperative results were reviewed from their records. Chi-square tests, Fisher's exact analyses, analyses of variance, and logistic regressions were performed to determine characteristics associated with @entity892 , and to identify factors related to @entity892 in pediatric @entity1 .The most common causes of injuries were traffic accidents in the 0 to 6 years old group, normal daily activities in the 7 to 12 years old group, and assaults in the 13 to 18 years old group. Floor @entity174 were the most common location in both the 0 to 6- and 7 to 12 years old groups, and medial-floor @entity174 were the most common location in the 13 to 18 years old group. The occurrence of preoperative @entity892 was related to ocular motility restriction and enophthalmos, but not with the age group, the gender, the cause of injury, or the @entity174 locations. The time interval from injury to surgery was significant in the outcome of @entity86 (P<0.01). A statistical difference was also found in the recovery time from @entity892 among the 3 age groups (P<0.01).The characteristics of orbital blowout @entity174 varied among the different age groups. It was related to 2 factors, the cause of @entity174 locations, which probably resulted from structural growth changes and differences in daily habits. @entity1 had a slower recovery from orbital @entity174 , and the younger the @entity1 , the longer it took for recovery from @entity892 after surgery.
