A morphometric study of foramen ovale

Abstract

AIm:To note the morphological variations and morphometric details of foramina ovale in dry adult skulls of Indian origin. mAterIAl and methOds: 82 dry adult human skulls of unknown sex and of Indian origin were obtained and variations in appearance and number of foramen ovale were noted. The length and width of the foramina ovale of both sides were determined using digital Vernier calipers and area (A) was also calculated and analyzed.results: Out of 82 adult skulls, the values for the right side was 7.64 ± 1.194 mm, 5.128 ± 0.827 mm and 30.808 ± 7.545 mm2 and for the left side the values was 7.561 ± 1.123 mm, 5.244 ± 0.950mm and 31.310 ± 8.262 mm2 respectively, for the mean length, width and area of the foramen ovale. The shape of foramen was typically ovale in most of the skulls (56.70%) with some bony variations such as spine, tubercles etc.COnClusIOn: There was no statistically significant difference between the two sides in length, width and area of foramen ovale and there was a positive correlation between lengths and areas of both sides. BulGulAr: 82 erişkin kafatasında foramen ovalenin sırasıyla ortalama uzunluk, genişlik ve alanı sağ tarafta 7.64 ± 1.194 mm, 5.128 ± 0.827 mm ve 30.808 ± 7.545 mm2, sol tarafta ise 7.561 ± 1.123 mm, 5.244 ± 0.950mm ve 31.310 ± 8.262 mm2 olarak saptandı. Çoğu kafatasında foramenin şekli tipik olarak oval (%56,70) olmakla birlikte bazı spinöz, tüberküler vs. kemik varyasyonları da mevcuttu. sOnuÇ: Her iki tarafta foramen ovalenin uzunluk, genişlik ve alanı açısından istatistiksel olarak anlamlı fark bulunmadığı ve her iki tarafın uzunluk ve alanları arasında pozitif korelasyon olduğu gözlendi.AnAhtAr sÖZCÜKler: Foramen ovale, Morfoloji, Morfometri, Kafatası, Sfenoid

Medicolegal Importance of the Foramen Ovale, in Determination of Sex, in Dried Adult Egyptians Human Skulls (Morphometric & Morphological Study)

“…Other forms represent 4-5%. This comes in accordance with previous studies done by Yanagi (1987) and Somesh et al (2011), as the oval shape was the common, then the almond shape.…”

Morphometric and Morphological Analysis of Foramen Ovale in Dry Human Skulls

“…There are some studies which indicates the abnormal morphology of the Foramen ovale, such that it can be occasionally covered by ossified ligaments stretching between the lateral pterygoid process and the sphenoid spine or its venous part may be compartmentalised by a bony spur located antero-medially resulting in doubled Foramen ovale [7]. An atypical position of foramen ovale and neighbouring osseous structures could influence the anatomical organisation of the nerves that run through this opening.…”

“…The mean length of the foramen ovale is about 3.85 mm in the newborn and about 7.2 mm in adults and its width extends from 1.81 mm in the newborn to 3.7 mm in case of adults. [6,7].Knowledge of topography and variations of the foramen ovale can prevent injury to the trigeminal nerve during surgical approaches.Therefore the study has been undertaken to know the difference in linear measurements of right and left foramen ovale in human skulls of Indian origin.…”

The size of the foramen ovale regarding to the presence and absence of the emissary sphenoidal foramen: is there any relationship between them?

“…It is a reasonable assumption that any change of the volume and shape of the venous plexus may alter FO shape and size. Searching the literature, variability exists as regards the FO types of shape (oval, truly oval, elongated oval, elongated, semicircular, almond, round, rounded, slit, irregular, D shape and pear) [7,23,37] and FO size (length and width) among studies. As regards FO length, the higher values were recorded by Patil et al [27] and Murugan and Saheb [22], while lower values were found by Kaplan et al [16], Natsis et al [23], Lang et al [17] and Agarwal and Gupta [1].…”
