PURPOSE To describe a new experimental flap for studying skin viability in rats. METHODS Twenty male Wistar rats weighing between 250-300g were divided into two groups: group A - McFarlane technique, a 4 x 10cm flap was used (McFarlane); and in group B modified McFarlane technique, a 3 x 10cm flap was used. Seven days later, the animals were sacrificed and the area of necrosis was evaluated i...

An important technical modification in the conventional medial based cross leg flaps is described by the authors. The technique involves resurfacing large triangular defects in the medial lower leg, ankle and foot. This modification, by virtue of narrowing the pedicle, will help the surgeon to maximize the inset avoiding delaying of the flap or flap loss. Secondary defects created by raising th...

INTRODUCTION We recently published an article in the International Journal of Surgical Case Reports titled: "Scrotal dartos-fascio-myo-cutaneous flap for penis elongation after catastrophic iatrogenic skin shaft sub-amputation: A case of recovery using an extremely adaptable flap". PRESENTATION OF CASE We propose a comment on a recent article titled "A case report of a complete degloving inju...

BACKGROUND There is a limited evidence base to guide surgeons on the ideal thickness of skin flaps during mastectomy. Here the literature relevant to optimizing mastectomy skin flap thickness is reviewed, including anatomical studies, oncological considerations, factors affecting viability, and the impact of surgical technique and adjuvant therapies. METHODS A MEDLINE search was performed usi...

Repairing surgical defects of the nasal tip is challenging, mainly because of the lack of freely mobile skin available peripherally. The Peng flap is a one-stage cutaneous flap that circumvents this difficulty by recruiting skin from the nasal dorsum and sidewall regions. The design produces a tridimensional shape perfectly adapted to the configuration of the nasal tip and allows for an inconsp...

Several animal models of skin flap construction were reported using biomaterials in a way similar to prefabrication. However, there are few animal model using biomaterials similar to prelamination, another main way of clinical skin flap construction that has been proved to be reliable. Can biomaterials be added in skin flap prelamination to reduce the use of autogenous tissues? Beside individua...
