An anatomical study of the pterygoalar bar and the pterygoalar foramen.

چکیده
The paper presents anatomical considerations on the pterygoalar bar and the pterygoalar foramen of the human skull. The pterygoalar bar is a bony bridge that stretches between the lateral pterygoid lamina and the greater wing of the sphenoid bone, while the space under this bar is termed the pterygoalar foramen. These structures were noted in 5 out of 70 investigated skulls. The length of the pterygoalar bar ranged from 4 to 8 mm, while the diameter of the pterygoalar foramen ranged from 7 to 11 mm. The presence of the pterygoalar bar is clinically important because it may disturb access to the foramen ovale during anaesthesia of the trigeminal nerve.

Radiographic study of ossification of the pterygospinous and pterygoalar ligaments by the Hirtz axial technique.
The correct radiographic identification of ossification of the pterygospinous and pterygoalar ligaments plays an important role in surgical procedures for the treatment of trigeminal neuralgia. Most of these procedures are performed through the foramen ovale, a site where these ligaments can be found to be partially or completely ossified. We studied the radiographic features of these ossified ...

Introduction Foramen ovale of the sphenoid bone serves as an important landmark for neurosurgeons in the procedures involving the trigeminal nerve. Shape and size of the Foramen ovale is subject to vary as similar to other foramina. But, the Foramen ovale which is divided into two compartments is a rare variation. We report here a case of bilateral atypical foramina ovalia which is divided into...

Understanding of morphological structures such as the sphenoid spine and pterygoid processes is important during lateral transzygomatic infratemporal fossa approach. In addition, osseous variations such as pterygospinous and pterygoalar bridges are significant in clinical practice because they can produce various neurological disturbances or block the passage of a needle into the trigeminal gan...

The foramen tympanicum is an anatomical variation that is created in the tympanic plate of temporal bone during the first year of life. The tympanic plate grows and foramen tympanicum is gradually closed by about the fifth postnatal year. However, due to a defect in normal ossification, foramen tympanicum sporadically remains throughout life. The construction of a shopping center in Tabriz, nor...
متن کاملInvestigating the supratrochlear foramen and septum in adult humerus bones: brief report
Background: The supratrochlear foramen (STF) is an important and relatively common anatomic variation in the lower end of the humerus in humans. In recent years it has become clear that STF should be emphasized because anatomical knowledge of STF is useful for anatomists, anthropologists, orthopedic surgeons, and radiologists. The anatomical structure of the humerus may play an important role i...
