Axial pattern flaps Flashcards
Axial pattern flaps are cutaneous flaps based on a named nutrient vessel
T
Axial pattern flaps have a pedicle containing a named cutaneous artery
T Vs random pattern flaps whose blood supply is based on the subdermal plexus
The paramedian forehead flap has a pedicle most commonly based on the supratrochlear artery
T
The abbe flap has a pedicle based on either the superior or inferior labial artery
T
The dorsal nasal rotation flap has a pedicle based on the dorsal nasal artery
T
Axial pattern flaps are usually staged surgical procedures.
T
Convex areas generally heal better with second intention than concave areas.
F Other way round.
Grafts rarely match the aesthetic results seen with flap reconstructive procedures.
T
The reduction of blood flow from the proximal to distal portion of the flap results in relative tissue hypoxia and challenges flap survival.
T
Flaps that have excessive width:length ratios may undergo distal necrosis.
F Excessive length:width.
Flaps inset under heightened tension show reduced perfusion.
T
Most flaps utilised in derm surgery are random pattern flaps.
T
Axial pattern flaps commonly used in facial reconstruction include the median and paramedian forehead flaps, the dorsal nasal flap, and the Abbe flap.
T
When most of a nasal subunit has been removed with tumour extirpation, the optimal reconstructive result may be achieved by replacing selective parts of the subunit.
F Replacing the entire subunit.
Random pattern flaps are an effective repair choice for nasal defects >2cm, alar or distal nasal defects, or full-thickness wounds
F
The forehead is generally preferred for nasal reconstruction when there is insufficient dorsal nasal skin.
T
The paramedian forehead flap and the cheek melolabial interpolation flap are both interpolation flaps with the base of the flap’s pedicle residing some distance away from the surgical wound (non-contiguous).
T
The cheek (melolabial) interpolation flap is a true axial pattern flap.
