In low- and middle-income countries, breast reconstruction is not widely practiced due to a lack of specialized equipment, skilled personnel, and high costs. The scarless latissimus dorsi flap is a useful technique which can harvest a major portion of the latissimus dorsi muscle using the same mastectomy incision without requiring repositioning of the patient, to cover the lower pole of prosthesis for reconstruction. The aim of this study was to assess and evaluate the cosmetic results and complications of scarless LD flap used as a lower pole cover in post-mastectomy breast reconstruction with implants. This is a pilot study of 18 breast cancer patients who underwent implant-based scarless LD flap breast reconstructions during a period of 4 years from 2017 to 2021. A questionnaire based on relevant subscales of BREAST-Q scores was completed by all the patients and used for evaluation. A total of 18 patients who underwent 20 surgeries were evaluated for the study. The median age was 44.5 years. The mean operative time was observed to be 164.50 min. The mean length of hospital stay was 3.1 days. From the Breast Q subscales, the mean cosmetic score was 31 out of 36 (range 27–36) (higher score reflecting better cosmetic outcome), and the mean physical well-being score was 17.25 out of 54 (range 12–29) (lower score reflecting better outcome). Overall complications were observed to be 20% which included minimal flap necrosis in 2 patients which was managed conservatively, and seromas in 2 patients which needed ultrasound-guided aspirations twice. There were no major complications. The scarless LD flap provides an adequate lower pole muscle coverage for implants in breast reconstruction. It has less morbidity and good cosmetic outcomes. It is time and cost-effective, requires no patient repositioning, and uses standard breast instruments.
