“…Several terminologies have been implemented to describe tumors around the dorsum sellae to the ventral of brainstem area, which includes dorsum sellae or clival meningioma, retrosellar meningioma and PCP meningioma ( 2 , 9 , 13 , 14 ). These tumors were later classified by Sodhi et al.…”

“…Several modifications were added to this approach using a simple frontotemporal approach or additional basal extension with frontotemporal orbito-zygomatic approach. These approaches provide optic canal decompression early in the surgery and direct access to the tumor, thus facilitating tumor dissection from neurovascular structures around the tumor ( 1 , 3 , 4 , 8 , 13 ).…”

“…Concerning these approaches, direct tumor manipulation was hindered by the neurovascular structures with an incapacious surgical corridor between these structures that increased the risk of injury. Furthermore, peeling off the cavernous sinus dura may lead to cranial nerve deficit and sinus thrombosis, as PCP meningioma may obstruct the inferior petrosal sinus ( 2 , 3 , 8 , 13 ).…”

BackgroundPosterior clinoid process (PCP) meningioma is an exceedingly rare entity. It remains the most challenging skull base lesion for neurosurgeons due to its treacherous location that insinuates amongst critical neurovascular structures. This article will describe the technical notes using the endoscopic endonasal approach that provide the earliest devascularization and detachment of the tumor PCP meningioma.MethodsWe are introducing the surgical implementation of an endoscopic endonasal approach to removing PCP meningioma. Furthermore, we perform a literature review of posterior clinoid process meningioma that undergoes surgical intervention, then summarize the benefits and limitations of each approach.ResultsWe present a case of right PCP meningioma that was removed using an endoscopic endonasal approach through the transposterior clinoid corridor in a 52-year-old-woman. We describe the technical notes in performing this approach to have the earliest devascularization and detachment of the tumor by performing posterior clinoidectomy. Safe tumor removal is performed with a wide and clear view of the surrounding neurovascular structure. Based on our database search, we found nine articles reported on the surgical management of PCP meningiomas, with a total number of 15 cases. All of the reported cases performed the tumor removal using the transcranial approach.ConclusionThe endoscopic endonasal transposterior clinoid approach circumvents all disadvantages faced by the traditional transcranial approach, providing the earliest approach to devascularized and detaching the tumor from its attachment at PCP. This approach demonstrates safety and efficacy, making it an acceptable alternative for PCP meningioma resections.
