Reattaching amputated ears is challenging. The retroauricular pocket technique, burying the ear segment, improves survival and minimizes deformity by enhancing nutrient supply and preserving tissue integrity.

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Microsurgery

Background:

  • Ear reconstruction presents significant challenges for plastic surgeons.
  • Traditional composite grafting and microsurgical replantation have limitations, including graft unreliability and technical complexity due to venous drainage issues.

Observation:

  • The retroauricular pocket principle, as advocated by Mladick et al., offers a novel approach.
  • This technique involves deepithelializing the amputated ear segment, reattaching it anatomically, and burying it in a retroauricular pocket.

Findings:

  • The retroauricular pocket technique increases the surface area for nutrient exchange, maximizing the graft's survival probability.
  • Preservation of the dermis-cartilage relationship minimizes cartilage warping, and spontaneous reepithelialization negates the need for skin grafts.

  • Successful application in five out of six patients demonstrates the technique's efficacy.

    • Implications:

    • This method offers a simpler, more reliable solution for ear segment reattachment compared to existing techniques.
    • It holds potential for improving outcomes in traumatic ear amputations, reducing patient deformity and the need for secondary procedures.
