The interclinoid ligaments between the anterior, middle and posterior clinoid process are occasionally ossified. A bony bridge between the anterior and middle clinoid process and another between the anterior and posterior clinoid process was found in a dry specimen of one adult sphenoid bone. It was found bilaterally, like a ring around the sella turcica. The occasional presence of this ossified interclinoid ligament may compress the internal carotid artery, interrupting the blood flow and may also compress the cranial nerves. So, the anatomical knowledge of such ossification is important and should be kept in mind and evaluated before proceeding to skull based surgery around the sella turcica region.
