Rhomboid Flap Reconstruction after Mastectomy for Locally Advanced Breast Cancer

Limberg flap in mastectomy T-junction necrosis: an underutilised technique

The Wise-pattern skin-sparing mastectomy (SSM) is well known for its efficacy in large ptotic breasts, and its safety in facilitating immediate breast reconstruction. An unfortunate sequalae for all SSM techniques is mastectomy skin flap necrosis (MSFN) with a reported range of occurrence of 5%-30%. For the Wise pattern, the common area of wound dehiscence or necrosis is the T-junction. Different techniques have been described in the management of MSFN-ranging from primary closure to local and distant flaps. Full thickness MSFN results in wound breakdown and can expose a prosthesis, subsequently closure must be obtained with potential for the prosthesis to be explanted. To date, there has been no reports in the literature of the usage of a rhomboid flap in an SSM with immediate prepectoral implant. We discuss our experience in the usage of this local cosmetic flap to avoid prosthesis loss and have reviewed the literature regarding MSFN, the application of the rhomboid (Limberg) flap in breast surgery and its applicability in MSFN to preserve underlying prosthesis.

Dufourmentel Flap for Scalp Reconstruction

Transposition flaps are useful for reconstruction of many skin defects. Limberg described a rhomboid rotation flap in 1946. Dufourmentel described an improved version of the Limberg flap in 1962. The Dufourmentel flap is also a quadrangular rhomboid flap which can be used in any area of the body except for the central face, the fingers, and the volar hand. The design of the Dufourmentel flap creates a wider base for this random flap, thus making it more reliable. Where tissue loss is significant, or where skin and soft tissue elasticity is limited, double opposing Dufourmentel flaps are useful. A variation of the Dufourmentel flap is described where a circular defect is converted to a square. The line of greatest extensibility is marked through the circular defect or lesion. A square is marked around the circle with one corner of the square tilted 10–20 degrees counterclockwise from the line of greatest extensibility. After marking corners A, B, C, and D, lines are marked extending BD and CD. The first incision, DE, will bisect the angle created by extending BD and CD. The second incision, EF, is roughly perpendicular to CD extended, but the angle at E is opened up a bit to create a wider base for the flap. Point D will rotate to point B, E rotates to C, and F translates to D. The invisible line DF should be approximately parallel to the line of greatest extensibility. When the defect is relatively large or where the surrounding tissues have limited elasticity, the above-described ideal variation of the Dufourmentel flap may not be possible because the flap may not rotate and advance all the way around without tension. In this case, double opposing Dufourmentel type flaps have been found to be useful by meeting each other at the halfway point.
