Postmastectomy "dog-ears" are cosmetically displeasing, can contribute to a poorly fitting bra, and may cause discomfort for patients. They occur most commonly in patients with high body mass index and/or large breasts and can be challenging to manage. To avoid the lateral dog-ear following simple mastectomy, we describe the M-plasty with the addition of a lipodermal flap. We demonstrate that the addition of a lipodermal flap not only flattens the lateral contour of the chest wall but also facilitates a tension-free closure. This helps reduce wound-healing issues in high-risk patients with multiple comorbidities, high body mass index, and large breast size.
