The rarity of severe nerve lesions encountered in surgically treated patients raises the question of better selection of candidates for surgery. Surgery is clearly indicated when FP is total, is of immediate onset, and is associated with a bad prognosis electromyogram pattern. In other settings, decisions are to be made based on high-resolution CT data and electromyogram results, thanks to a clinical survey and second electromyogram evaluation.

Surgery of intracranial meningioma in elderly patients is feasible when the SKALE score is 8 or greater. Prospective studies are required to validate this grading system.

The consensus opinion was that brainstem trauma is a primary factor in the variability of outcomes in NF2 patients. The significant co-factors in outcomes implied that ABI surgery should be accomplished with great care to minimize physical and venous trauma to the brainstem. It is clear that high levels of speech recognition, including high levels of open-set speech recognition, are possible with the ABI even in patients with NF2 and large tumors.

The point of convergence between the cortical veins and the SSS is a key area. The authors also hypothesize that the myoendothelial junction acts as a smooth sphincter and that it plays a role in cerebral venous hemodynamics and pathological conditions.
