Update on endoscopic endonasal resection of skull base meningiomas

Abstract: Using a 2-team approach, meningiomas of the skull base were successfully removed via an intranasal endoscopic technique. Although complete resection is typically possible even with large tumors, the lengthy resection required time for tumors larger than 60 cm(3) (diameter ≥4 cm) may obviate some of the advantages of this approach. The rate of postoperative CSF leak decreases when a synthetic dural substitute is added but does not approach zero.

“…The EEA for OGM also poses challenges in skull‐base reconstruction, because the NSF, so commonly used in extended endoscopic procedures, may not able to cover the entire defect, with some authors reporting augmenting the reconstruction with extracranial pericranial flaps . Other factors reported to pose a limitation for GTR in EEA include: (1) absence of a cortical cuff with neurovascular encasement; (2) significant brain edema; and (3) tumor size >4 cm . These factors have been flagged as relative contraindications, the importance of which having often been left to the discretion of the surgeon.…”

“…More recent reports show increased rates of GTR but still less than those reported for transcranial approaches. Limitations of GTR include: (1) extension beyond mid‐orbit in the coronal plane; (2) extension to the posterior table of the frontal sinus in the sagittal plane; (3) absence of a cortical cuff with neurovascular encasement; (4) extensive calcification; and (5) tumor size >4 cm …”

“…сти дна клиновидной пазухи в общей сложности залегают три канала, проходящие в переднезаднем направлении от медиального к латеральному краю,сошниковый, небный и крыловидный [1]. Наиболее медиально расположен сошниково-влагалищный канал, напоминающий небольшой костный желобок (см.…”

“…Указанные костные каналы открываются в крылонебную ямку. В небно-влагалищном канале располагаются глоточный нерв от крылонебного узла и глоточная артерия от третьей части верхнечелюстной артерии, которые намного меньше, чем видиев нерв и артерия в видиевом канале [1,2]. Задний конец крыловидного канала, который содержит в себе одноименные артерию и нерв, открывается в верхнюю часть переднелатерального края рваного отверстия (см.…”
