A case of a young infant with Chiari II malformation treated by only foramen magnum decompression was reported. The patient was a 3-month-old infant with a one-month history of stridor and respiratory distress. The myelomeningocele was surgically repaired. At the age of two weeks, a ventriculoperitoneal shunt had been inserted. On admission, MRI demonstrated Chiari II malformation. The shunt mechanism was functioning. Suboccipital craniectomy and upper cervical laminectomy from C1 to C5 level was performed. After the removal of the dural band at the foramen magnum level, good pulsation of the dura mater was demonstrated. After surgery, the stridor and respiratory distress disappeared. Foramen magnum decompression carried out by our surgical technique is advantageous because all the procedures are extradural and there are, therefore, fewer postoperative complications than the foramen magnum decompression techniques previously reported.
报告了一例仅接受枕骨大孔减压治疗的Chiari II型畸形幼儿病例。患者为一名3个月大的婴儿，有1个月的喘鸣和呼吸窘迫病史。脊髓脊膜膨出已通过手术修复。在2周龄时，插入了脑室腹腔分流管。入院时，MRI显示为Chiari II型畸形。分流装置功能正常。进行了枕下颅骨切除术和从C1至C5水平的上颈椎椎板切除术。在枕骨大孔水平切除硬膜带后，可见硬脑膜良好的搏动。术后，喘鸣和呼吸窘迫消失。我们的手术技术进行的枕骨大孔减压是有利的，因为所有操作均在硬膜外进行，因此与先前报道的枕骨大孔减压技术相比，术后并发症更少。
