Doubled Foramen Rotundum and Maxillary Nerve Fenestration
Surgical and Radiologic Anatomy, 2011Even though the doubled foramen rotundum (FR) can be identified once within the literature, there are no details of the contents at that level. We present here an anatomical case demonstrating the maxillary nerve (MN) duplication at the level of an unilateral doubled FR: the accessory nervous trunk of the MN separately left the trigeminal ganglion on ...

Foramen Rotundum Duplication on High-Resolution CT. Case Report
SN Comprehensive Clinical Medicine, 2021To report a case of an accessory canal arising from the floor of the foramen rotundum (FR) and extending to the infratemoral fossa. This case report describes the imaging findings of FR duplication on high-resolution CT in multiple planes. The FR is formed when the foramen anterius lacerum is divided into the superior orbital fissure and the FR ...

Narrow Foramen Ovale and Rotundum
Journal of Craniofacial Surgery, 2016Primary trigeminal neuralgia (TN) may occasionally occur in absence of neurovascular compression. A mechanism other than nerovascular compression may play a role in TN. High-resolution computed tomographies (CTs) of 21 consecutive TN patients without vascular compression during surgery and 30 healthy volunteers were retrospectively performed. Measuring

Transdural Propagation of Glioblastoma Through Foramen Rotundum
World Neurosurgery, 2018Glioblastoma, also known as glioblastoma multiforme, is the most common primary malignant cerebral tumor in adults. Although glioblastoma multiforme is one of the most aggressive tumors in the brain, propagation through the dura mater is rare.A 59-year-old man presented with progressive headache and aphasia.

A New Method of Locating Foramen Rotundum and its Anatomic Study
Journal of Craniofacial Surgery, 2015The purpose of this study is to provide a new method to locate the foramen rotundum (FR) based on the structures in the wall of sphenoid.Computed tomographic angiography images of 172 FR in adults and 10 bony specimens were reviewed. The measurement was on coronal, sagittal, and axial planes after multiplanar reconstruction.

Acta Neurochirurgica
The foramen rotundum and anterior cavernous sinus have traditionally been accessed by transcranial approaches that are limited by the high density of critical neurovascular structures. The transmaxillary approach provides an entirely extradural route to the foramen rotundum and anterior cavernous sinus.This patient with neurofibromatosis and facial ...

Variations at the skull base can result in misinterpretation of radiological imaging and occasionally, iatrogenic injury. Here, we describe, to our knowledge, the second reported case of a duplicated foramen rotundum. The morphometrics of this finding are documented and the anatomy and potential clinical consequences of such an anatomical variation ...
