Bone Structure01:55

Bone Structure

51.0K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Formation by Intramembranous Ossification

9.5K
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 Ossification

7.5K
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...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

8.3K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Bone Disorders01:29

Bone Disorders

5.0K
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...

Compact Bone01:27

Compact Bone

15.4K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Area of Science:

  • Oral and Maxillofacial Surgery
  • Pediatric Dentistry
  • Orthodontics

Background:

  • Heterotopic ossification (HO) typically occurs after trauma, surgery, or injury, leading to pain and restricted joint movement.
  • While reported in adults and children, HO in the infratemporal region, particularly affecting developing jaws, is exceptionally rare.
  • HO near the temporomandibular joint (TMJ) can impede the growth and development of the mandible and maxilla.

Purpose of the Study:

  • To report the first documented pediatric case of heterotopic ossification in the infratemporal region.
  • To highlight the potential impact of HO on craniofacial development in children.
  • To increase awareness of this rare condition among clinicians treating pediatric patients with jaw abnormalities.

Main Methods:

  • Case report detailing a pediatric patient with HO near the TMJ.
  • Clinical examination and radiographic assessment (e.g., CT scans) to diagnose and evaluate the extent of HO.
  • Review of English literature to identify similar cases and understand the condition's prevalence and characteristics.

Main Results:

  • A unique case of heterotopic ossification was identified in the infratemporal region of a pediatric patient.
  • The HO was found in close proximity to the temporomandibular joint (TMJ).
  • The condition demonstrated an impact on the normal growth and development of the adjacent mandible and maxilla.

Conclusions:

  • This case represents the first reported instance of pediatric heterotopic ossification affecting the infratemporal region and TMJ.
  • HO in this location poses a significant risk to craniofacial development during childhood.
  • Early diagnosis and management are crucial for mitigating the adverse effects of HO on jaw growth.
