“…For example, matrix Gla protein inhibits calcification in soft tissues while osteopontin slows down the ossification in hard tissues [3]. Archana et al [4] studied 250 adult dried human skulls for the presence of interclinoid bars. They reported a total incidence of 22 % of various types of interclinoid bars.…”

The ossification of ligamentous structures in various part of the body may result in clinical problems. The complete sella turcica bridge corresponds to the complete ossification of the interclinoid ligaments. Fifty dry adult skull bones were studied for presence of ossified interclinoid ligaments. Three skull bones show sella turcica bridge, of which one shows bilateral and two show unilateral. The ligamentous or bony interclinoid connections have important neuronal and vascular relations and are both clinically and surgically important. The knowledge of detailed anatomy of the interclinoid ligament can increase the success of diagnostic evaluation and surgical approaches to the region. The existence of a bony caroticoclinoid foramen may cause compression, tightening, or stretching of the internal carotid artery. Further, removing the anterior clinoid process is an important step in regional surgery; the presence of a bony caroticoclinoid foramen may have high risk.

“…The following parameters were recorded: 1) Presence/absence of the foramen 2) Complete/incomplete foramen 3) Unilateral/bilateral foramen 4) Dimensions of the foramen (maximum and minimum diameters of the foramen) 5) Dimensions of the ligament (width and thickness of the ligament) 6) Sex of the skull. For the classification of the interclinoid bars, the method proposed by Rani Archana et al [8] and the method proposed by Keyers [9] were used: Rani Archana et al [8] classified interclinoid bars into four types: Type I: -Bridge present between anterior and middle clinoid process (carotico clinoid foramen). Type II: -Bridge between anterior, middle and posterior clinoid process.…”

Back ground: The carotico clinoid foramen is formed by an osseous bridge between tip of the middle and anterior clinoid processes of the sphenoid bone and transmits one of the segments of internal carotid artery (ICA).Context: The existence of a bony or osseous carotico clinoid foramen may cause compression, tightening or stretching of the ICA, especially of the clinoidal segment and cause complications in regional surgery.Purpose: The present study is an effort to study the carotico clinoid foramen in skulls and observe various parameters like presence or absence, unilateral or bilateral, complete or incomplete, extent, dimensions of the ligament, dimensions of the foramen and sexual dominance.Results: Presence of complete foramen was found in 12% and incomplete foramen was 26%. The mean width and thickness of the ligaments was found to be greater on the left side and greater in males. The size of the foramen was found to be more on the left side and in males. Complete foramina were found to be more in males while incomplete foramina were found equally in both sexes. Unilateral foramen were found to be more in females while bilateral foramina were found to be more in males. Conclusion:Considering the fact that most of the anatomy text books do not provide a detailed description of the carotico clinoid ligament or foramen, the present study proves especially relevant to neurosurgeons in day to day clinical practice.Implication: Knowledge of the prevalence of carotico clinoid foramen helps the neuro-surgeons for pre-operative scanning and precautions can be taken to prevent fatal complications during surgery. Further, removal of the anterior clinoid process is an important step in regional surgery, for which additional risk is involved. Therefore detailed anatomical knowledge of the carotico clinoid foramen is of utmost importance, to increase the success of regional surgeries.KEY WORDS: carotico clinoid foramen, clinoid process, internal carotid artery, clinoidectomy, interclinoid foramen.

“…In all cases, the anterior, middle, and posterior clinoid processes were examined on both right and left sides to reveal their relationship and the incidence of ossified interclinoid bars. For the classification of the interclinoid bars, the method proposed by Rani Archana et al 10 and the method proposed by Keyers 11 were used. In Type II variety of osseous bridge a fourth subtype of fusion was also observed where a combination of any of the above two subtypes was present between the adjacent clinoid process and this subtype was termed as mixed type 10 .…”

A group of intrinsic ligaments of the sphenoid bone which connect the anterior, middle & posterior clinoid processes occasionally get ossified and give rise to various types of ossified interclinoid bars. In present study the incidence of various types of ossified interclinoid bars were observed in 200 dry human skulls of unknown age & sex belonging to department of Anatomy of various Medical Colleges of Gujarat region. The interclinoid bars are classified on the basis of two classifications, proposed by Rani Archana et al and Keyers. Rani Archana et al, classified interclinoid bars into four types : Type I (caroticoclinoid foramen) bridge present between anterior and middle clinoid process, Type II bridge between anterior, middle and posterior clinoid process, Type III bridge between anterior and posterior clinoid process and Type IV bridge between the middle and posterior clinoid process. Each interclinoid bar was classified into contact, incomplete, complete types based on the classification of Keyers. In present study total incidence of interclinoid bars was 18%. Type I were present in 10.5%, out of which 8% were complete and 2.5% were incomplete. Types II in 3.5%, amongst them 2% were complete and 1.5% was mixed. Type III in 4%, out of which 2% were complete and 2% were incomplete. Total incidence of caroticoclinoid foramens was 14.5%, out of which 11.5% were complete and 3% were incomplete. Total incidence of sellar bridge was 7.5%, out of which 4.5% were complete and 3% were incomplete. Presence of osseous interclinoid bars may cause compression of surrounding structures like the cavernous sinus and its content, sphenoid sinus and pituitary gland. Therefore, detailed anatomical knowledge of various types of interclinoid bars can increase the success of diagnostic evaluation and surgical approaches to the region.
