Muscle

Breast reconstruction plays a vital role in the restoration of form post-mastectomy. Autologous breast reconstructions using both free as well as pedicled flaps form the bulk of the breast reconstruction in our centre. This study seeks to evaluate the muscle-sparing modification of the pedicled transverse rectus abdominis myocutaneous (MS-TRAM) flaps against conventional transverse rectus abdominis myocutaneous (TRAM) flaps, in an attempt to marry the benefits of both and minimise the drawbacks of each technique. A retrospective analysis of 20 women, 10 of whom had undergone unilateral immediate breast reconstruction with pedicled MS-TRAM flaps after skin-sparing mastectomy (MS group), and 10 who had undergone the conventional pedicled TRAM flap (control group) by the same surgeon (S. Ho) over a two-year period from 2013 to 2015 was performed. Patients’ records were reviewed, assessing patient demographics including age, smoking status and evaluating the operative time, time to ambulation, length of hospital stay, pain scores and abdominal bulge rates. Mean operative time was not significantly longer in the MS group. Pain scores were lower in the MS group. The length of hospital stay was not significantly different between the two groups. Abdominal bulge rates at 24 months postoperatively were 0% in the MS group patients and 10% in the control group. The pedicled MS-TRAM flap is an excellent breast reconstruction option that is comparable to the conventional TRAM flap. It preserves innervated muscle in the donor site that reduces time to ambulation and postoperative pain. It does not add significantly to surgical time and does not require microvascular anastomosis
