Oncoplastic breast surgery technique for retroareolar breast cancer: a technical modification of the Grisotti flap in patients with short nipple to inferior mammary crease distance

摘要

The introduction of breast conservation surgery together with advances in oncoplastic techniques has revolutionized the management of retroareolar breast tumours. Traditionally, cancers in this location were often managed with central excision and primary closure or mastectomy. More recently, oncoplastic breast-conserving techniques such as the Grisotti mammoplasty have been increasingly encouraged as an alternative option as it allows oncological safe margin resections while restoring cosmesis. The use of a Grisotti flap enables safe resection of a retroareolar tumour with concurrent reconstruction of the defect using a local rotational advancement dermoglandular flap allowing a satisfactory cosmetic result in term of contour and projection. This technique is often limited to those patients with sufficient native nipple-inferior mammary fold (IMF) distance to accommodate for some inevitable post-operative reduction in this distance. We describe a modification of the original description, such that satisfactory cosmetic outcome can be achieved, even in patients with a short nipple areolar complex to inframammary fold distance.
