Insights

The foramen ovale (FO) position relative to the lateral pterygoid plate (LPP) in children is consistent across ages, sexes, and sides. This relationship allows for safe percutaneous procedures in most pediatric patients.

Area of Science:

  • Anatomy
  • Pediatric Imaging
  • Surgical Access

Background:

  • The foramen ovale (FO) is a critical anatomical landmark.
  • Understanding its relationship with the lateral pterygoid plate (LPP) is essential for surgical procedures.
  • Variations in FO position can impact procedural success and safety.

Purpose of the Study:

  • To investigate the positional relationship between the foramen ovale (FO) and the lateral pterygoid plate (LPP) in a pediatric population.
  • To identify potential differences based on age, sex, or side.
  • To assess the implications for percutaneous procedures in children.

Main Methods:

  • Analysis of 360 pediatric computed tomography (CT) scans (ages 1-18).
  • Classification of FO position relative to LPP into four types: lateral, medial, direct, and removed/far.
  • Statistical analysis to determine associations with sex, side, and age groups.

Main Results:

  • The most common FO positions relative to LPP were direct (35.2%) and lateral (34%).
  • FO localization was not significantly associated with sex (p=0.952), side (p=0.899), or pediatric age periods (p=0.794).
  • Results align with findings in adult literature.

Conclusions:

  • The positional relationship between the FO and LPP in children is consistent and not influenced by age, sex, or side.
  • Posterior tracing of the LPP base offers approximately 80% successful access to the FO in pediatric patients.
  • Percutaneous procedures targeting the FO are feasible in selected children across various demographics.

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

The Auditory Ossicles01:11

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
