The Superiorly Based Partial Rectus Abdominis and External Oblique Flap for Lower Pole Coverage in Prosthetic Breast Reconstruction: A Prospective Cohort Study of 47 Consecutive Flaps.

BACKGROUND: This study evaluated health related quality of life and morbidity in patients who had a superiorly based partial rectus abdominis and external oblique (SPREO) flap for lower pole coverage as a component of 2-stage prosthetic breast reconstruction. METHODS: A prospective cohort study of patients undergoing immediate and delayed 2-stage breast reconstruction including a SPREO flap for lower pole coverage was conducted. The BREAST-Q and a study-specific questionnaire were used to determine outcomes after this procedure. BREAST-Q questionnaires were completed preoperatively and postoperatively and compared with normative values. RESULTS: BREAST-Q questionnaires were completed by 27 women. The mean patient age was 54.3 ± 9.6 years. Mean BREAST-Q scores improved significantly between preoperative and postoperative time points in Satisfaction with Breasts (preoperative 43.2 ± 26.9, postoperative 66.2 ± 19.5, P = 0.001) and Psychosocial Wellbeing (preoperative 59.4 ± 16.4 postoperative 75.5 ± 19.4, P = 0.002). Mean scores were not significantly different in the domains Physical Wellbeing Chest, Physical Wellbeing Abdomen and Sexual Wellbeing. Postoperative BREAST-Q scores were significantly higher (P < 0.05) than previously published normative scores in Satisfaction with Breasts. CONCLUSIONS: This study reports the use of the SPREO flap for lower pole coverage in 2-stage prosthetic breast reconstruction and demonstrates that it may be a useful addition to the existing repertoire of flaps used in breast reconstruction.

The Superiorly Based Partial Rectus Abdominis and External Oblique Flap: A New Technique for Breast Asymmetry Reconstruction.

Breast asymmetry has a wide spectrum of presentations with several employable strategies for surgical correction. Historically, the external oblique muscle has proven to be a versatile flap option for the reconstruction of both local and distant defects. It has also been described for use in breast reconstruction for coverage of the lower pole of implant prostheses. The external oblique muscle flap can be harvested in several ways to capture overlying fat and skin. In this study, we describe the use of a superiorly based partial rectus and external oblique flap for surgical correction of lower pole breast hypoplasia. This flap provides vascularized autologous volume to the lower pole of the breast with minimal donor morbidity. Other advantages of this flap are that it can increase the nipple to inframammary fold distance and lower the inframammary fold. This technique represents an evolution of an under-utilized flap and is the first study describing the use of the external oblique flap in the management of breast asymmetry.
