Inferior dermal flap in immediate breast reconstruction

Area of Science:

• Plastic Surgery
• Breast Reconstruction Techniques
• Oncoplastic Surgery

Background:

• The inferior dermal flap is utilized in breast reconstruction with implants or tissue expanders, potentially replacing acellular dermal matrix.
• This technique is suitable for patients with high BMI or breast ptosis desiring size reduction during mastectomy and reconstruction.
• It leverages de-epithelialized excess skin from skin-sparing mastectomy to avoid acellular dermal matrix, offering a cost-effective solution.

Observation:

• The procedure involves a skin-sparing mastectomy with de-epithelialization of the inferior skin flap to create an inferior dermal pedicle.
• A retropectorally placed gel implant is secured by suturing the inferior dermal flap to the pectoralis major muscle and a muscle-sparing serratus pedicle.

Findings:

• The technique was successfully performed in multiple patients, with one case detailed for a 54-year-old female with DCIS.
• Postoperative assessments at 6 weeks demonstrated excellent cosmetic outcomes without any complications.

Implications:

• The inferior dermal flap presents a straightforward and repeatable method for breast reconstruction.
• It significantly reduces costs by eliminating the need for acellular dermal matrix.
• This approach yields superior cosmetic results for patients with high BMI and breast ptosis requiring breast reduction during mastectomy.
