Insights

Hyoid bone (HB) size increases with age in children, while its angle decreases after late childhood. These growth patterns can help estimate HB size in pediatric populations.

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Anatomy

Background:

  • The hyoid bone (HB) is a unique U-shaped bone in the neck.
  • Understanding hyoid bone morphology changes with age is crucial for pediatric development studies.

Purpose of the Study:

  • To analyze the age-related alterations in hyoid bone (HB) morphology in children.
  • To establish growth patterns for estimating hyoid bone size in pediatric populations.

Main Methods:

  • Computed tomography (CT) scans of 129 children (ages 1-17) were analyzed.
  • Measurements included HB length, greater horn dimensions, body width/height, and horn angles.
  • Hyoid bone shapes were classified into four types (U, B, D, V).

Main Results:

  • Anterior-posterior length, greater horn lengths, body width/height, and posterior horn distance increased with age (p<0.001).
  • The angle of the greater horns decreased with age (p=0.022).
  • Hyoid bone shape correlated significantly with pediatric age (p<0.001) but not gender (p=0.153).

Conclusions:

  • Hyoid bone dimensions generally increase until the postpubescent period.
  • The angle of the greater horns shows a decrease after late childhood.
  • Developed linear functions can potentially estimate hyoid bone size in children.

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...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

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 ...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
