Le Fort-type fractures are very rare in children, and there is a paucity of literature presenting their frequency and characteristics. The purpose of this study was to determine the etiology, frequency, and fracture patterns of children with severe facial trauma associated with pterygoid plate fractures in a pediatric cohort.
We performed a retrospective cohort study of all children aged younger than 16 years with pterygoid plate and facial fractures who presented to our institute between 1990 and 2010. Patient charts and radiologic records were reviewed for demographic and fracture characteristics. Patients were categorized into 2 groups as per facial fracture pattern: non-Le Fort-type fractures (group A) and Le Fort-type fractures (group B). Other variables including dentition age, frontal sinus development, mechanism of injury, injury severity, and concomitant injuries were recorded. Univariate methods were used to compare groups.
We identified 24 children; 25% were girls, and 20.8% were of nonwhite race. Most presented with Le Fort-type fracture patterns (group B, 66.7%). Age was significantly different between group A and group B (mean, 5.9 years and 9.9 years, respectively; P = .009). No significant differences in Injury Severity Score, rate of operative repair, and length of stay were found between groups.
Most children with severe facial fractures and pterygoid plate fractures presented with Le Fort-type fracture patterns in our cohort. The mean age of children with Le Fort-type fractures was greater than in those with non-Le Fort-type patterns. However, Le Fort-type fractures did occur in younger children with deciduous and mixed dentition.
勒福氏骨折在儿童中非常罕见,且缺乏关于其发生率和特征的文献报道。本研究的目的是确定儿科队列中伴有翼突板骨折的严重面部创伤患儿的病因、发生率及骨折类型。
我们对1990年至2010年间在我院就诊的所有16岁以下伴有翼突板骨折和面部骨折的儿童进行了一项回顾性队列研究。查阅患者病历和放射学记录以获取人口统计学和骨折特征信息。根据面部骨折类型将患者分为两组:非勒福氏骨折(A组)和勒福氏骨折(B组)。记录其他变量,包括牙龄、额窦发育情况、损伤机制、损伤严重程度及合并伤。采用单变量方法对两组进行比较。
我们共纳入24名儿童;其中25%为女孩,20.8%为非白人种族。大多数患儿表现为勒福氏骨折类型(B组,66.7%)。A组和B组的年龄存在显著差异(平均年龄分别为5.9岁和9.9岁;P = 0.009)。两组在损伤严重程度评分、手术修复率及住院时间方面未发现显著差异。
在我们的队列中,大多数伴有严重面部骨折和翼突板骨折的儿童表现为勒福氏骨折类型。勒福氏骨折患儿的平均年龄大于非勒福氏骨折患儿。然而,勒福氏骨折确实也发生在乳牙列和混合牙列的年幼儿童中。
