  • The lateral wall of the cavernous sinus is primarily formed by the continuation of the meningeal layer of the dura, flowing medially up from the floor of the middle cranial fossa, over the cavernous sinus, to the clinoid processes before forming the diaphragma sella. (radiopaedia.org)
  • In some cases, surgery is needed to repair the sella to prevent CSF from leaking into the nose and sinuses. (nih.gov)
  • With empty sella syndrome, CSF has leaked into the sella turcica, putting pressure on the pituitary. (nih.gov)
