Cryptotia recurrence lowering technique with additional acellular dermal matrix graft.

Area of Science:

• Plastic Surgery
• Congenital Anomalies
• Regenerative Medicine

Background:

• Cryptotia is a congenital ear anomaly characterized by an absent retroauricular sulcus.
• Existing surgical techniques for cryptotia correction may lead to skin deficiency.
• There is a need for improved methods with better cosmetic results and fewer complications.

Purpose of the Study:

• To evaluate a novel surgical technique for cryptotia correction utilizing acellular dermal matrix (ADM).
• To assess the efficacy and safety of ADM grafts in improving cosmetic outcomes and reducing complications.

Main Methods:

• A V-Y plasty and Z-plasty technique was employed for cryptotia correction in five deformities across four patients.
• A thick acellular dermal matrix (ADM; MegaDerm) graft was applied to the cephalo-auricular angle to enhance ear projection.
• The flap was transposed to complete the surgical repair.

Main Results:

• No cryptotia recurrence was observed in any of the four patients.
• The procedure resulted in favorable cosmetic appearances without postoperative complications like infection or seroma.
• The study period was from January 2014 to February 2018.

Conclusions:

• Acellular dermal matrix (ADM) grafting combined with V-Y and Z-plasty presents a viable alternative for cryptotia correction.
• This technique potentially reduces donor-site morbidity compared to autologous cartilage grafts.
• The ADM graft method may offer a more cost-effective solution than cadaver cartilage grafts.
