  • Damage to the tentorium can cause compression of the occipital lobes, leading to vision problems and other neurological symptoms.
  • Surgery to relieve increased intracranial pressure may involve incising the tentorium to allow for expansion of the brain tissue.
  • The tentorium is attached to the posterior clinoid processes and the superior margin of the transverse sinus, forming a strong and stable fold of dura mater.
