The importance of perfusion pressure and fluid viscosity parameters for relevant vascular mapping of the mandible.

While traditional anatomical studies provide valuable vascular maps, their reliance on uncontrolled perfusion parameters (pressure, flow rate, viscosity) risks bias in defining vascular territories. This letter addresses these limitations with pressure-controlled perfusion, demonstrating that mandibular vascular saturation occurs at 75–95 mmHg, aligning with physiological arterial pressure. These findings call for a dynamic, pressure-driven redefinition of angiosome.
