Free Flap Outcome in Irradiated Recipient Sites: A Systematic Review and Meta-analysis.

Unlabelled: The impact of previous radiotherapy on free flap outcome is still a subject of debate. Clinical investigations have come to divergent conclusions and the true effect of radiotherapy (XRT) on flap survival is not definitely known. Most studies investigating the factor often have their methodological limitations such as lack of statistical power as a consequence of the overall low failure rates together with few irradiated cases.

A Modified Rhomboid Flap for Medial Canthal Reconstruction.

Unlabelled: The reconstruction of medial canthal defects is often challenging in achieving continuity of color and texture, obtaining adequate tissue for large defects, and the reproduction of natural external appearance with inconspicuous scars. We describe a technique for reconstruction of the medial canthal area, using a modified rhomboid flap.

Methods: The technique is based on the use of a modified rhomboid flap for medial canthal defects-superiorly based on the root of the nose for defects mostly above the medial canthal tendon, inferiorly based on the cheek for defects mostly below the medial canthal tendon, and in cases of large defects, using a combination of the two flaps.

Presence of Biofilms on Polyurethane-Coated Breast Implants: Preliminary Results.

Polyurethane-coated breast implants seem to be associated with lower medium- and long-term capsular contracture rates in comparison to textured or smooth implant surfaces. Although the etiology of capsular contracture is uncertain, bacterial biofilms have been suggested to trigger chronic peri-implant inflammation, eventually leading to capsular contracture. It is unknown whether polyurethane-coated implants are less prone to biofilm colonization than other implant surfaces.
