Myomammary Flap of Pectoralis Major Muscle for Breast Reconstruction: New Technique

Abstract. Simple mastectomy and modified radical mastectomy is still the preferred surgical technique for management of breast cancer, as it is always in the second stage (II). Breast reconstruction in Egypt is always accompanied by reduction mammoplasty of the other breast. The new method utilizes a myomammary flap from the other side. This flap depends on the other breast being of moderate or large size. The flap being transferred depends on the pedicle of the pectoralis major tunneled under the skin. The new technique utilizes the nipple on the healthy side to reconstruct the nipple of the new breast at the same time. A reduction mammoplasty was achieved in healthy contralateral huge breasts. A total of 23 female patients were submitted for breast reconstruction using a pectoralis major myomammary flap from the other relatively large breast. The flap depended on a blood supply from the pectoral branch of the thoracoacromial artery. Good cosmetic results were achieved in 60% of cases, fair results in 25%, and unsatisfactory results in 15%. In conclusion, this new technique of breast reconstruction is suitable especially for patients with large, healthy breasts and for relatively poor patients.
