Craniocerebral disproportion is a gross discrepancy between the volume of the brain and the volume of the cranial cavity that persists after initial treatment of the underlying condition, which in most cases is severe congenital hydrocephalus. The goals of treatment are control of intracranial pressure and arrest of the growth of the head. These goals can usually be accomplished by cerebrospinal fluid shunts supplemented as needed by shunting of extracerebral fluid collections. When conventional methods fail, or when in the setting of extreme degrees of craniocerebral disproportion they seem doomed to failure, reduction cranioplasty may simplify management. A surgical technique is described, three cases are presented, and indications are discussed.
颅腔与脑体积 disproportion是指在对潜在疾病进行初始治疗后，脑体积与颅腔体积之间仍存在的明显差异，在大多数情况下，潜在疾病为严重先天性脑积水。治疗的目标是控制颅内压并阻止头部生长。这些目标通常可通过脑脊液分流来实现，必要时可辅以脑外积液分流。当传统方法失败时，或者在极度颅腔与脑体积 disproportion的情况下，传统方法似乎注定会失败，颅骨减压成形术可能会简化治疗。本文描述了一种手术技术，介绍了三例病例，并讨论了手术指征。
