When the brain is too swollen, neurosurgeons will perform craniectomy (removing a portion of your skull bone) to manage increased intracranial pressure. The piece of skull bone flap removed will be placed back into the head after the brain swelling resolves, which usually takes up to a few weeks. Where would you like to have you skull bone flap preserved? In your abdomen or in a frrezer, assuming that both options carry the same infection rates and prognosis. 翻譯：腦太腫時，為了降腦壓，神外醫生會作頭骨移除術（craniectomy）。幾個禮拜後，等腦消腫以後，醫生會再開一次刀把頭骨放回去，叫頭顱整形術（cranioplasty)。在感染率，預後都相同的前提下，大家會希望被拿下來的那一塊頭骨保存在哪裡？自己的肚子裡還是冰箱裡？

Abdominal preservation/肚皮下

Cryopreservation/冰箱裡
