    Microscopic examination of de-epithelized dermal pedicles revealed significant variation in the removal depth of epidermis and pilosebaceous structures. This variability raises questions about nipple viability and potential cyst formation.

    Area of Science:

    • Plastic Surgery
    • Dermatology
    • Surgical Anatomy

    Background:

    • Nipple viability is often attributed to the dermal plexus circulation.
    • The surgical technique of de-epithelization is commonly employed in plastic surgery procedures.
    • The precise extent and impact of de-epithelization are not fully understood.

    Purpose of the Study:

    • To microscopically evaluate the extent of de-epithelization in dermal pedicles.
    • To assess the variability in de-epithelization techniques among surgeons and procedures.
    • To question the established understanding of nipple viability factors.

    Main Methods:

    • Microscopic examination of 38 biopsy specimens from de-epithelized dermal pedicles.
    • Analysis of de-epithelization depth across different surgeons, procedures, and bilateral cases.

    Main Results:

    • Significant variation was observed in the depth of the de-epithelization plane.
    • De-epithelization typically removed the epidermis and the upper dermis containing the pilosebaceous apparatus.
    • Inconsistency was noted even within bilateral procedures performed by the same surgeon.

    Conclusions:

    • The variability in de-epithelization depth challenges the presumed critical role of the dermal plexus circulation for nipple viability.
    • The findings suggest a need for further investigation into the implications for epidermal inclusion cyst development.
    • Surgical technique standardization may be important to ensure predictable outcomes in procedures involving de-epithelized dermal pedicles.
