Insights

The Vidian canal (VC) in children grows larger and shifts position with age. This study mapped VC size and location in 180 pediatric patients using CT scans.

Area of Science:

  • Anatomy
  • Pediatric Imaging
  • Craniomaxillofacial Surgery

Background:

  • The Vidian canal (VC) is a crucial anatomical structure in the skull base.
  • Understanding its dimensions and position in children is vital for surgical planning and interpreting imaging studies.

Purpose of the Study:

  • To determine the size and topographic position of the Vidian canal (VC) in a pediatric population.
  • To establish normative data for VC anatomy in children aged 1-18 years.

Main Methods:

  • Computed tomography (CT) scans of 180 pediatric subjects (1-18 years) were analyzed.
  • Measurements included VC length and distances to specific craniofacial landmarks.
  • VC locations relative to the sphenoid sinus and pterygoid process were classified into distinct types.

Main Results:

  • VC dimensions and distances to landmarks (vomerine crest, midsagittal plane, foramen rotundum, sphenoid sinus) were quantified.
  • VC location was categorized by type in relation to the sphenoid sinus and pterygoid process.
  • VC positional types showed a correlation with advancing pediatric age, but not with sex or laterality.

Conclusions:

  • The Vidian canal (VC) demonstrates age-related changes in pediatric patients.
  • Increasing age is associated with greater VC protrusion into the sphenoid sinus.
  • The VC's position shifts from medial to lateral relative to the medial pterygoid plate as children age.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
