Variations in epidermal thickness in expanded human breast skin
1Department of Plastic and Reconstructive Surgery, Karolinska Hospital, Stockholm, Sweden.
Summary
Tissue expansion temporarily increases epidermal thickness in breast reconstruction patients. This thickness returns to normal six months after expansion ceases, indicating a reversible change.
Area of Science:
- Plastic Surgery
- Dermatology
- Regenerative Medicine
Background:
- Tissue expansion is a common technique for breast reconstruction.
- Morphological changes, including epidermal and dermal thickness alterations, occur during tissue expansion.
- Human studies on these changes are limited.
Purpose of the Study:
- To investigate changes in epidermal thickness during and after tissue expansion for breast reconstruction in women.
- To assess the reversibility of epidermal thickening post-expansion.
Main Methods:
- Biopsies of expanded breast skin were taken from 11 women at three time points: before expansion, at maximal expansion, and six months post-reconstruction.
- Light microscopy was used to assess epidermal thickness.
Main Results:
- A statistically significant increase in epidermal thickness was observed at maximal expansion (p < 0.05).
- Epidermal thickness before expansion and six months after reconstruction showed no significant difference.
Conclusions:
- Tissue expansion leads to a temporary increase in epidermal thickness.
- The epidermis returns to its baseline thickness within six months of completing tissue expansion.
