The incidence of pneumocephalus after supratentorial craniotomy has been reported to be as high as 100%. However, transformation of postoperative pneumocephalus into tension pneumocephalus (symptomatic intracranial air) is a rather rare phenomenon. Tension pneumocephalus after posterior fossa surgery is reported mainly when the surgery is performed in a sitting position. We hereby report on a patient who developed brain-stem tension pneumocephalus in the early postoperative period after posterior fossa craniotomy for an exophytic brainstem astrocytoma, operated in the prone position. A complete locked-in syndrome resolved following surgical relief of the trapped air.
幕上开颅术后气颅的发生率据报道高达100%。然而，术后气颅转变为张力性气颅（有症状的颅内积气）是一种相当罕见的现象。后颅窝手术后的张力性气颅主要报道于手术采取坐位时。我们在此报告一例患者，其因外生性脑干星形细胞瘤行后颅窝开颅手术，手术采取俯卧位，术后早期发生脑干张力性气颅。经手术解除 trapped air后，完全性闭锁综合征得以缓解。 （注：原文中“trapped air”可能有误，推测应为“trapped air”，直译为“被困气体”，结合语境可能是“积气”之意。）
