Intraorbital meningiomas are challenging lesions to excise because of their location and the restricted surgical corridor available due to the presence of important neighboring structures. Lesions located in the posterior one-third of the orbit require skull base approaches for their exposure and safe resection. Frontoorbital and modified orbitozygomatic (OZ) craniotomies may facilitate the exposure and resection of masses in the posterior intraorbital space. Specifically, the one-piece modified OZ craniotomy provides many advantages of the "full" OZ craniotomy (which includes a more extensive zygomatic osteotomy). The modified OZ approach minimizes the extent of frontal lobe retraction and provides ample amount of space for the surgeon to exploit all the working angles to resect the tumor. The following video presentation discusses the nuances of technique for resection of an intraorbital meningioma through modified OZ approach and optic nerve decompression. The nuances of technique will be discussed. The video can be found here: http://youtu.be/fP5X2QNr5qk .
眼眶内脑膜瘤由于其位置以及由于存在重要的邻近结构而导致的手术通道受限,因此很难切除。位于眶后三分之一的病变需要颅底入路才能暴露和安全切除。额眶和改良眶颧(OZ)开颅术可能有助于暴露和切除后眶内空间的肿块。具体而言,一体式改良 OZ 开颅术具有“全”OZ 开颅术(包括更广泛的颧骨切开术)的许多优点。改良 OZ 入路最大限度地减少了额叶的牵拉程度,并为外科医生提供了充足的空间,以利用所有工作角度切除肿瘤。以下视频演示讨论了通过改良 OZ 入路和视神经减压切除眼眶内脑膜瘤的技术细节。将讨论技术细节。该视频可在此处找到:http://youtu.be/fP5X2QNr5qk。
