“…Gupta et al (2005) (9) observed the mean length of ACP in Nepalese dry skulls on the right side as 10.74 ± 2.37 and on left side as 10.83 ± 1.20, which were slightly less than the length of ACP in North Indian dry skulls. A study by Kapur and Mehić, (7) on 200 dry skulls from Sarajevo and Bosnia average length was 9.9 ± 1.6 mm and 8.7 ± 1.5 mm on right and 9.3 ± 1.4 and 8.3 ± 2.1 mm on left side in males and females skulls respectively, which was less as compared to the North Indian skulls and comparable to a South Indian study done by Shahin Hunnargi et al (2008), (10) in their metrical and non-metrical study with mean length of 10.68 ± 1.9 mm and 9.96 ± 1.71 mm on right and left side respectively.…”

“…Andaluz et al (2006), reported relatively small values for both height (8.67±2.63 mm) and width (6.57±1.68 mm). Hunnargi et al (2008), reported in their dry skull study, differences between South Indian, Nepalese and Korean ACP dimensions on both the right and left side. They found that the average length of the right ACP was 10.68±1.90 mm and that of the left Hayashi (2004) and by Gupta et al (2005).…”

CELIKOGLU, E.; IS, M.; CETINER KALE, A. & TORUM EROGLU, B.Pre-operative measurement of the morphometry and angles of the anterior clinoid process (ACP) for aneurysm surgery. Int. J. Morphol., 34(4):1333Morphol., 34(4): -1338Morphol., 34(4): , 2016. SUMMARY:The anterior clinoid process (ACP) is proximal to vital structures, such as the optic nerve, internal carotid artery and ophthalmic artery; therefore, study of its anatomy is important in guiding and defining surgery. We studied the anatomical structure of the ACP, including the angle formed by the apex of the ACP triangle, and its orientation, to provide information for easier and safer surgery. The measurement was performed on the axial planes of 242 cranial computerized tomography (CT) scans and 27 adult Turkish skulls of both sexes. The length of the ACP, width of the ACP at its base, the angle formed by the apical angle of the ACP triangle and the orientation of the ACP defined according to the sagittal midline were examined. In the Turkish skulls, the length and width of the ACP were similar to previous studies. Our study was the first to measure the angle and orientation of the ACP. The mean angle was 39. 67±12.64 (16.6-89.5) and 135 posterior (55 %) and 107 medial (45 %) orientations. Surgical complications can be avoided by pre-operative radiological planning using axial CT scans and by determining whether the morphology is Type 2 (long, narrow, acute-angled), which requires total resection.

“…The anatomical relationships of the ACP, ON, chiasm, internal carotid artery (ICA), ophthalmic artery (OA) and falciform ligament (FL) are complex and represent important variations. In the past three decades a number of researchers have examined some parts of the supra-and parasellar region, yet the anatomy of this area remains complex and varied (3,7,(9)(10)(11)(12)19,(22)(23)(24)29,31,32,34,35). This region also is one of the most common that can be affected by many neoplastic and vascular neurosurgical lesions.…”

“…The C5 segment of the ICA extends from the PDR to the DDR and lies immediately below the ACP. The DDR is a landmark for the end of the C5 segment and the beginning of the ophthalmic (C6) segment ( Figure 11) (19). The PDR loosely surrounds the ICA.…”

The aim of this study was to better define the microsurgical anatomy of the supra/parasellar region and describe variations of the anterior clinoid process (ACP). MATERIAL and METHODS:Fifteen formalin-fixed cadaver heads and 25 dry skulls were used to define the microsurgical anatomy of the ACP and related structures. The presence of the caroticoclinoid foramen (CaCF) as well as other relevant measurements were all noted. Radiological examination of the CaCF was also demonstrated on dry skulls. RESULTS:Interosseous bridges, which form between the anterior and middle clinoid processes or connect all three (anterior, middle and posterior) clinoid processes, were found in 30% of the specimens. The average basal width, length and thickness of the ACP were 7.3 mm, 9.7 mm and 5.4 mm, respectively. Length of the optic nerve (ON) up to the falciform ligament (FL) was 10.9 mm; length of the ON under the FL was 2.7 mm; length of ON after removal of the ACP and unroofing the optic canal was 21.1 mm. CONCLUSION:This study contributes to the relationship of important vascular, neural, bone and dural layers of this region and also demonstrates the variations of ACP by means of microsurgical dissections and radiological examinations. BULGULAR: İnterosseöz köprü, anterior ve orta klinoid proçes birleşmesiyle veya diğer 3 klinoid proçesin (anterior, orta, arka klinoid proçes) birleşmesiyle oluşur ve bu varyasyon %30 oranında tespit edilmiştir. Anterior klinoid proçesin bazal genişliği, uzunluğu ve kalınlığı sırası ile 7,3 mm, 9,7 mm ve 5,4 mm olarak bulunmuştur. Optik sinirin falsiform ligamana olan uzaklığı 10,9 mm, falsiform ligaman altındaki uzaklığı 2,7 mm, optik sinirin anterior klinoid proçes alındıktan ve optik kanal açıldıktan sonraki uzunluğu 21,1 mm olarak bulunmuştur. SONUÇ:Çalışmada anterior klinoid proçes varyasyonları ve bu bölge ile ilgili önemli vasküler, nöral ve kemik yapıların ilişkisi mikrocerrahi ve radyolojik çalışma ile yeniden değerlendirilmiştir.

Metrical and non-metrical study of anterior clinoid process in South Indian adult skulls

Abstract: The result of the present investigation suggests that ACPs of South Indian skulls are highly variable and, are marginally larger and thicker than ACPs of Nepalese and Korean origin.
