METHODS: This was a retrospectively cohort study on neonates born between July 2016 and August 2021. Neonates diagnosed with depressed skull fractures within one week of birth through X-ray and/or brain ultrasonography were included, and their mothers\' obstetric characteristics were reviewed.
RESULTS: There were 12 cases in 6791 live births. Five women were over 35 years old. All except two were nulliparous. Five cases were delivered from labor induction and others presented with spontaneous labor. Except for two cases, delivery occurred within an hour after full cervical dilatation. Two cases were assisted by vacuum. None displayed fetal distress signs such as low Apgar scores below 7, meconium staining, and umbilical cord pH under 7.2. All depressed fractures were found in the right parietal area. Three cases resulted in focal hyperechoic lesion in brain ultrasonography and two of them showed small hemorrhage-like lesion in magnetic resonance imaging. All depressed skull fractures improved within 6 months in followed X-rays or ultrasonography.
CONCLUSIONS: There was no definitely associated obstetric condition for depressed skull fracture of neonates although nulliparous women were majority of the affected cases.
方法:这是一项针对2016年7月至2021年8月出生的新生儿的回顾性队列研究。包括通过X线和/或脑部超声检查在出生后一周内诊断为凹陷性颅骨骨折的新生儿。并对其母亲的产科特征进行了回顾。
结果:6791例活产中有12例。五名妇女年龄超过35岁。除两个外,其余均为未产。5例因引产而分娩,其他人则表现为自发分娩。除了两种情况,分娩发生在宫颈完全扩张后一小时内。2例采用真空辅助治疗。没有显示胎儿窘迫体征,例如低Apgar评分低于7,胎粪染色,脐带pH低于7.2。所有凹陷性骨折均在右侧顶叶区域发现。三例在脑部超声检查中导致局灶性高回声病变,其中两例在磁共振成像中显示出小的出血样病变。所有凹陷性颅骨骨折均在X线或超声检查后在6个月内得到改善。
结论:尽管在受影响的病例中大多数为未分娩妇女,但新生儿颅骨凹陷性骨折没有明确相关的产科疾病。
