The pretemporal trans-cavernous trans-Meckel's trans-tentorial trans-petrosal approach: a combo skill in treating skull base meningiomas.
Observational study in Journal of neuro-oncology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeSurgical treatments for skull base meningiomas are challenging. We found that most of these lesions (75%), despite locating at the anterior, middle or posterior fossa, could be dealt with a combo skill-the pretemporal trans-cavernous trans-Meckel's trans-tentorial trans-petrosal approach (PCMTP), which adopted the same curvilinear skin incision as for the classic pterional approach. Our aim of this study is to validate the application of this technique in treating skull base meningiomas.
methodsPatients underwent surgical intervention at our institute during 2010-2018 were retrospectively reviewed. We statistically analyzed the clinical, radiological, and pathological outcomes.
resultsIn total, 109 patients operated with at least part of the PCMTP combo technique were included. The median follow-up time was 26.6 months. Tumor locations were categorized into: Zone I-sphenoid ridge, olfactory groove, and juxtasellar meningiomas which could be dealt with pterional approach. Zone II-clinoidal and cavernous sinus meningiomas which could be dealt with pretemporal trans-cavernous approach. Zone III-Meckel's and Incisura meningiomas which could be dealt with trans-Meckel's trans tentorial approach. Zone IV-petroclival menigiomas which could be dealt with trans-petrosal approach. When an extensive tumor occupied the anterior, middle, and posterior fossa, the whole combination of the PCMTP technique was applied. The mortality rate is 3.7% (4 patients). Three patients (2.8%) suffered from postoperative deterioration and required occasional assistance. The location of tumor was associated with different Simpson grade removal (p = 0.0015) and resection rate (p < 0.001).
conclusionThe PCMTP is effective in treating skull base meningiomas.
