foramina of the skull base (CT) - W-Radiolog

The primary foramina in the skull include the optic foramen, supraorbital foramen, foramen magnum, foramina of cribriform plate, and foramen rotundum (3). The optic foramen lies in the sphenoid and facilitates the passage of the ophthalmic artery and nerve from the optic canal into the orbit (4). The supraorbital foramen occupies the frontal bone (5). This foramen allows the passage of the supraorbital vein, artery, and nerve into the orbit. Meanwhile, the foramen magnum occupies the. The foramen rotundum (FR) is a short canal in the greater sphenoid wing at the skull base inferior to the superior orbital fissure. It connects the middle cranial fossa and the intracranial compartment with the pterygopalatine fossa (PPF) anteriorly [ 1 , 2 ] Foramen rotundum The foramen rotundum is one of the several circular apertures (the foramina ) located in the base of the skull , in the anterior and medial part of the sphenoid bone . The mean area of the foramina rotunda is not considerable, which may suggest that they play a minor role in the dynamics of blood circulation in the venous system of the head A peanut-shaped foramen (arrow) is seen lateral to foramen rotundum (arrowhead). the foramen rotundum, we, like Sondheimer, be­ lieve this structure transmits emissary veins. Be­ cause this variant is commonly seen on CT, we propose that a name be established for it and suggest the term inferior rotunda/ canal

  1. (A) CT scout view is utilized to help localize foramen rotundum in patients. Characteristics of the scanogram include semi-coronal position, orientation parallel to the plane connecting external acoustic pore and ipsilateral maxillary third molar bone. (B) The CT scan that captured simultaneously the foramen rotundum and its external and internal openings was used to design needle puncture route. Note that the white dots on the left top maxillary surface are transactional view of.
  2. Methods: Paranasal computed tomography (CT) scans of adults without sinonasal pathology were included. On axial cuts, the anteroposterior distances from the SPF to maxillary line, anterior head of the middle turbinate, basal lamella of the middle turbinate, choanal arch, and posterior fontanel of the maxillary sinus ostium were measured. While on coronal cuts, the vertical distances from the SPF to the nasal floor was measured. The registered measurements were then studied and statistically.

  4. Many vital anatomical structures are related to the sphenoid sinus including vidian canal (VC) and foramen rotundum (FR). The sphenoid bone is formed of body, lesser and greater wings and paired pterygoid process (PP). The medial and lateral PP are caudal perpendicular extension from the sphenoid sinus body
  5. Tumor can reach the pterygopalatine fossa and then extend intracranially via the foramen rotundum. Such spread can enlarge the osseous foramen. Of equal importance is the obliteration of the fat through which the tumor must pass as it approaches the skull base. Obliteration of the fat in the pterygopalatine fossa is a key finding 1-5]. Fat pads at the openings of more peripheral canals and.

Objectives: We report on an optimized CT-guided percutaneous infrazygomatic of maxillary nerve through the foramen rotundum (FR) to treat V2 trigeminal neuralgia (TN) using personalized RFA needles based on patient's individual CT-image parameters. Patients and methods: 176 patients with isolated V2 TN were included. If the entry of the percutaneous needle into the FR canal was blocked by the. Perineural spread occurs commonly along cranial nerves V, III, IV, and VI through foramen rotundum, foramen ovale, superior and inferior orbital fissures. Perineural spread in parotid malignancies occurs along the facial nerve via stylomastoid foramen. Perineural spread along the cranial nerves IX, X, XI, and XII with intracranial extension occurs along the jugular foramen and hypoglossal canal The left foramen rotundum is widened on the CT ( dashed arrow in F ). Paranasal sinus malignancies comprise only 0.2% of all malignancies, with 80% occurring in the maxillary sinuses. Primary sphenoid sinus neoplasms are extremely rare, accounting for only 1%-2% of paranasal sinus malignancies. Squamous cell carcinoma, sinonasal undifferentiated carcinoma, and adenoid cystic carcinoma may be. OBJECTIVE. Although CT-guided selective percutaneous radiofrequency thermocoagulation (PRFT) via the foramen rotundum (FR) has been used in the clinic as a novel successful treatment for isolated, second division (maxillary nerve [V2]), idiopathic trigeminal neuralgia (ITN), there is only very limited related literature published to date Title: Osseous Anatomy of the Orbital Apex Author: David L.

100 consecutive CT scans of the paranasal sinuses performed for any cause, were reviewed retrospectively to look for the sphenoid sinus and its anatomical relationship to the foramen rotundum and vidian canal. All the computed tomography scans were performed using Philips Ingenuity 128 slice CT scanner. 3 mm slice contiguous images were taken, and 1 mm slice reconstruction was performed. Postoperative CT imaging revealed that the cerebellar tonsil was back in the normal position, indicating that the preoperative Chiari malformation was possibly due to decreased CSF volume.

Background: The computed tomography (CT)-guided radiofrequency ablation (RFA) of the maxillary nerve (V2) via foramen rotundum (FR) approach has been reported to offer the highest rates of pain relief in V2 trigeminal neuralgia (TN). However, the access to FR may be obstructed by the greater wing of the sphenoid bone DOI: 10.4103/JASI.JASI_56_20 Introduction: The aim of this study was to evaluate vidian canal (VC) and foramen rotundum (FR) and their anatomical relationships with adjacent structures using computed tomography (CT) in a Turkish subpopulation.Material and Methods: CT images of 150 patients were retrospectively evaluated. Various morphometric measurements (distance from FRs to midline, distance. (A) Non-enhanced axial and (B) off sagittal >coronal multiplanar reconstruction CT images through the cryoablation probe (arrow) obtained at the end of the freeze cycle showing ice formation (arrowheads) extending adjacent to the foramen rotundum. (C) Non-enhanced axial CT image showing placement of a second cryoprobe (arrow) with ice ball (arrowhead) in contact with the foramen ovale Only foramen rotundum left exceeded 1.0 mm, with a mean range of 1.03 mm in the vertical (z) coordinate. Foramen rotundum was difficult to identify by using volumetric slices of the 3D CBCT images; thus, the volumetric 3D image (Fig 6) was used. Since in this image it is difficult to locate the end of the canal representing foramen rotundum, it was decided to place the landmark on its border. The maxillary nerve enters the PPF through the foramen rotundum and remains superolateral to the ganglion to give rise to its zygomatic branch while continuing to the infraorbital groove as the infraorbital nerve. 4 During its anterolateral course, the infraorbital nerve constitutes an important surgical landmark that defines the PPF (medial) from the infratemporal fossa (lateral). Neural rami.

Methods: In the present study, foramen rotundum was visualized as a round structure with prominent sclerotic margins locat-ed near ethmoid cells, maxillary sinus or orbital cavity in X ray images. X-rays (radiographs) of 17 dry skulls and 7 half dry skulls were performed with Phillips Digital Diagnost X-Ray.

In the wing, there are also three foramina- foramen rotundum, foramen ovale and foramen spinosum. Through these openings, nerves and arteries pass in the cranial cavity. The lesser wing of sphenoidal bone separates the anterior and medial cranial fossa and form the lateral border of the optic canal [3]. Development . The foramen spinosum size in adults is around 2.56mm long and 2.1 mm wide. In. Is There a Relationship Between Optic Canal, Foramen Rotundum, and Vidian Canal?

Paranasal sinus dimensions, optic canal (OC), foramen rotundum (FR), vidian canal (VC), bilateral FR (FRFR), bilateral vidian canal (VCVC), VC-foramen rotundum (VCFR), and VC-optic canal (VCOC) distances were measured Radiation dose is a key factor in CT, which should not be underestimated. Thus, in this study, we examined the question of how radiation dose in the CT of the nose and the paranasal sinuses can be reduced while still maintaining a clinically good and, satisfactory picture quality.
