抄録

Anterior clinoidectomy is an important skull base technique in the surgical treatment of aneurysms; however, certain complications are associated with this technique. Here, we developed a standardized extradural anterior clinoidectomy for improving surgical safety and retrospectively analyzed the procedural outcomes. The key steps of this technique include opening the superior orbital fissure, elevating the dura propria, using minimum drilling around the optic canal, maintaining hemostasis of the cavernous sinus, preserving the ophthalmic artery, and using the temporal fascia and abdominal fat during dura closure. Between 2014 and 2017, nine patients underwent extradural anterior clinoidectomy using these standardized procedures. Subsequently, no surgical complications were observed in any patient. Thus, we suggest that standardized extradural anterior clinoidectomy is useful for preventing surgical complications.
