Impact of Incision Placement on Ischemic Complications in Microsurgical Breast Reconstruction

Nipple Reconstruction Using the "Arrow Flap" Technique: Outcomes and Patients Satisfaction

INTRODUCTION

Skin-sparing mastectomy (SSM) entails complete removal of the breast tissue and the nipple and areola complex (NAC) with preservation of as much of the overlying skin as possible. The preservation of the natural skin envelope during SSM improves the aesthetic outcome of immediate breast reconstruction, but the lack of NAC determines that the reconstructed breast remains anatomically incomplete with not always satisfactory final results. For this purpose, the aim of the present study was to investigate and evaluate the impact of nipple reconstruction after skin sparing and skin reducing mastectomy on the patients' perception and intimate life.

MATERIALS AND METHOD

This was a comparative single-center prospective study that involved 42 patients underwent NAC reconstruction after SSM. A pre- and postoperative quality-of-life and psychological questionnaires Breast-Q questionnaire (Breast Conserving therapy module) were given to all the patients before the surgery and 6 months after. The statistical analysis with chi-square test was performed.

RESULTS

After 6 months a prevalence of patients reported to be very satisfied in regard to shape, appearance, naturalness, projection, position and symmetry. The study shows an overall improvement in all the psychological items analyzed with statistically significant difference regarding: "patient's satisfaction," "self-confidence," "appearance of the breast."

CONCLUSION

The authors believe that the NAC reconstruction has useful functional and aesthetic results particularly appreciated by patients who feel demoralized after breast demolition surgery.

Nipple Sparing Mastectomy Technique to Reduce Ischemic Complications: Preserving Important Blood Flow Based on Breast MRI

BACKGROUND

Nipple-sparing mastectomy (NSM) with immediate breast reconstruction is commonly performed. However, nipple areolar complex (NAC) and mastectomy skin necrosis represent significant complications requiring reoperation and revision. Breast MRI, often obtained for oncologic assessment, can visualize the dominant breast and NAC vascular supply. This study describes the surgical technique utilizing breast MRI blood flow information to preserve important NAC blood supply, thereby, reducing ischemic complications.

METHODS

After IRB approval, a prospectively maintained database of all NSM by a single breast surgeon from 2018 to 2020 formed the study group. Preoperative contrast enhanced Breast MRI analysis determined the dominant NAC blood supply. Intraoperatively, the dominant Internal Mammary Artery Perforator (IMP) to the NAC was preserved (IMP-NSM). The IMP-NSM surgical technique preserving the IMP blood flow, evaluation of breast MRI blood flow patterns, surgical findings, and ischemic complications were analyzed.

RESULTS

114 NSM were performed in 74 patients (mean age: 49 years [range, 22-73 years], BMI 25.8 kg/m² [range, 19-41 kg/m²]). Breast MRI identified the dominant IMP to the NAC in 92%. IMP preservation was successful in 89% (101/114). Necrosis requiring NAC removal occurred in 0.9% (1/114), and skin necrosis reoperation in 1.8% (2/114). Including all post-operative necrosis occurred in 10.5% (12/114), statistically significantly lower compared to the literature for NSM assessing MRI blood flow data without surgical IMP preservation (necrosis 24.4%, p < 0.001) (Bahl et al. in J Am Coll Surg 223(2):279-285, 2016) utilizing Doppler for IMP preservation (necrosis 37%, p < 0.001) (Swistel et al. in Plast Reconstr Surg Glob Open 2(8):e198, 2014) and dividing the IMP in all (necrosis 31.4%, p < 0.001) (Ahn et al. in Eur J Surg Oncol 44(8):1170-1176, 2018).

CONCLUSIONS

The IMP-NSM surgical technique preserves the dominant blood supply to the NAC, thereby, decreasing ischemic complications.
