Decompressive hemicraniectomy (DHC) is a lifesaving procedure which every neurosurgeon should master early on. As indications for the procedure are growing, the number of patients eventually requiring skull reconstruction via cranioplasty also increases. The posterior question mark incision is a straightforward alternative to the classic trauma-flap and can easily be adopted. Some particularities exist one should consider beforehand and are discussed here in detail.
Surgical steps, aids, and pitfalls are comprehensively discussed to prepare surgeons who wish to gain experience with this type of incision.
Due to the lower complication rate after cranioplasty, the posterior question mark incision has superseded the traditional pre-auricular starting anterior question mark incisions, in our department for the performance of decompressive hemicraniectomies.
去骨瓣减压术（DHC）是一种救生程序，每个神经外科医生都应该尽早掌握。随着该手术适应证的增加，最终需要通过颅骨成形术进行颅骨重建的患者数量也在增加。后问号切口是经典创伤皮瓣的一种直接替代方法，并且易于采用。这里详细讨论了一些在手术前需要考虑的特殊性。
全面讨论了手术步骤、辅助工具和陷阱，以帮助那些希望在这种切口类型上获得经验的外科医生。
由于颅骨成形术后并发症发生率较低，后问号切口已取代传统的耳前起始的前问号切口，成为我们科室进行减压性半颅骨切除术的首选。
