Lumber Defects01:23

Lumber Defects

490
Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
Shakes are minor fractures that run along or across the wood's annual rings, while wane is...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

1.3K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Spongy Bone01:09

Spongy Bone

7.7K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Compact Bone01:27

Compact Bone

16.2K
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...

Bone Disorders01:29

Bone Disorders

5.1K
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...

The Hyoid Bone01:12

The Hyoid Bone

4.9K
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...

Summary

Stafne bone defects (SBDs) are typically found in the mandibular angle. This case highlights an SBD in the ascending ramus, emphasizing the importance of recognizing rare presentations to avoid unnecessary surgery.

Area of Science:

  • Dentistry
  • Oral and Maxillofacial Surgery
  • Radiology

Background:

  • Stafne bone defects (SBDs) are typically asymptomatic, well-defined, radiolucent lesions located in the posterior mandible, often near the angle.
  • Classic SBD presentation allows for radiographic diagnosis, usually obviating the need for biopsy.
  • Atypical SBD locations can pose diagnostic challenges, potentially leading to misdiagnosis and unnecessary interventions.

Observation:

  • A 57-year-old male incidentally discovered a Stafne bone defect (SBD) in the left mandibular ascending ramus via panoramic radiography.
  • Further imaging confirmed a lingual concavity consistent with an SBD.
  • Retrospective analysis showed the lesion was present for at least 5 years without radiographic changes.

Findings:

  • This report details only the eleventh documented case of an SBD involving the mandibular ascending ramus.
  • Atypically located SBDs, such as in the ascending ramus, can mimic other pathologies, complicating diagnosis.
  • The rarity of ascending ramus SBDs underscores the potential for diagnostic ambiguity.

Implications:

  • Accurate radiographic interpretation is crucial for diagnosing SBDs, especially in atypical locations.
  • Recognizing rare SBD presentations can prevent misdiagnosis and avoid unnecessary surgical procedures and associated morbidities.
  • This case emphasizes the diagnostic utility of imaging for SBDs, regardless of location, preventing invasive treatments.
