Clinical characteristics of petroclival meningioma and the impact of resection degree on its prognosis

The functional benefit of resection in PCMs is modulated by CS invasion and WHO grade. The proposed RUS and decision algorithm provide a quantitative, evidence-based framework for individualized surgical planning, shifting the paradigm from a universal goal of maximal resection toward a risk-adapted strategy aimed at optimizing functional preservation without compromising oncologic control. Prospective multicenter validation is warranted.
