Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Summary

High ear piercing can lead to perichondritis. This study found no significant difference in ear cartilage damage between piercing guns and needles, suggesting hygiene and aftercare are key for preventing infection.

Area of Science:

  • Otolaryngology
  • Plastic Surgery
  • Forensic Pathology

Background:

  • High ear piercing is linked to increased perichondritis incidence.
  • Cartilage damage from piercing predisposes the ear to infection.
  • Piercing guns may cause more cartilage damage than needles, but evidence is lacking.

Purpose of the Study:

  • To compare the extent of ear cartilage damage caused by different piercing techniques.
  • To histologically evaluate injury patterns from piercing guns versus needles.

Main Methods:

  • Twenty-two human cadaver ears were pierced using two types of piercing guns (Caflon, Blomdahl), a hand-powered system (Studex), and a piercing needle.
  • Transverse sections of the pin tract were analyzed to quantify damage to cartilage and perichondrium.

Main Results:

  • All piercing methods resulted in similar patterns of injury, including perichondrial stripping and cartilage damage.
  • The exit site showed the most damage (mean length 0.43 mm).
  • No significant differences in the extent of injury were observed between the piercing techniques.

Conclusions:

  • Contrary to assumptions, all ear piercing methods cause comparable damage to cartilage and perichondrium.
  • The risk of post-piercing perichondritis is likely similar across all techniques.
  • Focus on hygiene and aftercare is crucial for preventing perichondritis, rather than the piercing method itself.
