Nonmetric analysis of caroticoclinoid foramen in foothills of Himalayas: Its clinicoanatomic perspective

The caroticoclinoid foramen in fetal and infantile orbitosphenoid, presphenoid, and sphenoid bones: developmental and neurosurgical considerations

“…Likewise, a meta-analysis by Ertürk et al 4 found the CCF in 20.51% (104/507) of crania. Jha et al 8 found the CCF in 22.22% of crania (24/108). Likewise, the present study found the CCF in 21.4% (21/98) of crania.…”

“…With regard to CCF types (i.e., complete, near-complete, and partial types), in adult populations the most common form of CCF is that of an incomplete or partial type. 4,8,9,11,16,23 There is general agreement among reports studying the CCF in adults that the CCF is most often found unilaterally. 4,[7][8][9]16 Conversely, this study found a unilateral CCF in one-third of instances (33.33%; 7/21); otherwise, the CCF was found bilaterally (66.66%; 14/21).…”

With striking similarity, the study performed by Keyes, 11 which analyzed a similar racial demographic, black and white individuals, found the CCF (what he referred to as the clinocarotid canal or anterior interclinoid canal) unilaterally in approximately one-third of instances (250/762; 32.8%) and bilaterally in approximately two-thirds of instances (512/762; 67.2%).…”

The erroneous eponym of the carotico-clinoid foramen of Henle: attribution is due to Alexander Monro (primus)

“…[1,[4][5][6][7][8][9][10][11][12][13][14][15][16] However, Henle was not the first to describe the CCF.…”

“…[3] Therefore, the carotico-clinoid is frequently noted in neurosurgical literature.A literature review regarding the CCF reveals numerous manuscripts that either use the eponymous term carotico-clinoid foramen of Henle or otherwise state that the CCF was first described by Henle in 1885. [1,[4][5][6][7][8][9][10][11][12][13][14][15][16] However, Henle was not the first to describe the CCF.Although Henle mentions the foramen carotico-clinoideum in his 1885 text 'Handbuch der systematischen Anatomie des Menschen', Alexander Monro (primus) described the CCF over a century earlier in his 1726 text 'The anatomy of the humane bones' (Figure 1). [17,18] Monro notes that anterior clinoid processes are frequently joined with the posterior clinoid processes or with the "Body of the Bone itself, by a bony Cross-bridge under which the Carotide Arteries pass" (Figures 2 and 3).…”
