Use of the MacCarty keyhole burr hole and the inferior orbital fissure provides simplicity and safety to perform the one-piece frontotemporal orbitozygomatic (FTOZ1) approach.
We performed the FTOZ1 approach with its three subtypes (i.e., total, temporal, and frontal) in cadaveric head specimens in the Goodyear Laboratory and subsequently in surgical cases.
The orbitozygomatic osteotomy, when added to a frontotemporal craniotomy, comprises the frontotemporal orbitozygomatic (FTOZ) approach, provides an expanded exposure to the anterior and middle cranial fossae, and enables the surgeon to create a window to the posterior cranial fossa. The MacCarty burr hole is used to facilitate orbital cuts, and the anterolateral portion of the inferior orbital fissure connects the orbital cuts to the zygomatic cuts. This allows the FTOZ1 craniotomy flap to be "out-fractured" with ease. The three types of FTOZ1 approach, i.e., the total, the temporal, and the frontal, are described step by step.
Understanding the MacCarty keyhole burr hole and the microsurgical anatomy of the inferior orbital fissure is essential to performing the FTOZ1 approach. The three types of FTOZ1 approach enable the surgeon to tailor the approach according to the surgical exposure needed for each lesion.
使用麦卡蒂锁孔钻孔和眶下裂可使整块额颞眶颧（FTOZ1）入路的操作更简便、安全。
我们在固特异实验室的尸体头部标本上，随后又在手术病例中实施了FTOZ1入路及其三种亚型（即全型、颞型和额型）。
眶颧截骨术与额颞开颅术相结合构成额颞眶颧（FTOZ）入路，可扩大对前颅窝和中颅窝的暴露范围，并使外科医生能够在后颅窝开一个窗口。麦卡蒂钻孔用于辅助眼眶切开，眶下裂的前外侧部分将眼眶切开与颧骨切开连接起来。这使得FTOZ1开颅皮瓣能够轻松“向外折断”。逐步描述了FTOZ1入路的三种类型，即全型、颞型和额型。
了解麦卡蒂锁孔钻孔和眶下裂的显微外科解剖结构对于实施FTOZ1入路至关重要。FTOZ1入路的三种类型使外科医生能够根据每个病变所需的手术暴露来调整入路方式。
