眶颧开颅术是颅底手术的主要入路之一，提供宽的、多向的进入前颅窝和中颅窝以及基底尖的通道。完全切除眶颧肌杆增加了暴露角度，减少了手术视野的工作深度，并使脑内回缩最小化。然而，在许多病例中，只需要全眶颧入路所提供的部分暴露。根据所治疗的特定病变调整骨切除的程度可以帮助降低入路相关的发病率，同时保持其优势。作者描述了眶上和颞下改良眶颧入路的技术细节，并讨论了其使用的手术指征。眶颧入路的改良是颅底手术不断适应普通神经外科实践的一个例子。
The orbitozygomatic craniotomy is one of the workhorse approaches of skull base surgery, providing wide, multidirectional access to the anterior and middle cranial fossae as well as the basilar apex. Complete removal of the orbitozygomatic bar increases the angles of exposure, decreases the working depth of the surgical field, and minimizes brain retraction. In many cases, however, only a portion of the exposure provided by the full orbitozygomatic approach is needed. Tailoring the extent of the bone resection to the specific lesion being treated can help lower approach-related morbidity while maintaining its advantages. The authors describe the technical details of the supraorbital and subtemporal modified orbitozygomatic approaches and discuss the surgical indications for their use.Modifications to the orbitozygomatic approach are an example of the on,going adaptation of skull base procedures to general neurosurgical practice.
