Principle of flap Flashcards
types II and IV, particularly)
are known to have the least reliable skin paddles, most particularly
distally
T
Sartorius, upper arm are type C faciocutanous flap
F type A
the propeller flap is an island
flap that reaches the recipient site through an axial rotation
T
The perforator location in the propeller flap closest to the defect is preferred for a wider angle of
rotation to minimize tension on the pedicle
T
Skeletonizing the pedicle in the propeller flap toward the flap can increase pedicle length
T
Design the skin paddle larger than the defectfor tension-free closure,
even with postoperative edema
T
is designed as
two opposing V-Y flaps oriented parallel to the longitudinal axis
of the defect,in key stone flap
T
Lateral Arm Flap may be harvested as a chimeric flap with bone
T
Lateral Arm Flap drawback
inconsistent perforator anatomy, short pedicle length, small vessel caliber, and challenging dissection
The deltoid insertion may also be divided to increase pedicle length in lateral arm flap
T
The Lateral antebrachial cutaneous nerve must be divided but can
be used to create a sensate flap
F The posterior antebrachial cutaneous nerve must be divided but can
be used to create a sensateflap
popularity of radial forarm flap arises from
the ease of dissection; robust, reliable vascularity; malleability;
and ability to support associated tissues such as bone, tendon, and
nerve
the most cause of failure of radial forearm flap is venous congestion
F the versatility arises from the multiple venous drainage options,
including the superficial system based on the larger cephalic vein
and/or the deep system based on the paired venae comitantes of the
radial artery
radial forearm flap can also be used for functional purposes
T
radial artery that runs between
the brachioradialis and flexor carpi radialis in the distal forearm
T
Lateral antebrachial cutaneous nerve, palmaris longus tendon,
and superficial veins may be incorporated in the harvest and followed
along their courses prior to transection in radial forearm flap
T
Sensation can’t preserved with rectus muscle flap
F Sensation can be restored with harvest of branches of thoracolumbar spinal nerves
When a muscle flap is used in rectus muscle flap , the
borders of the rectus muscle are identified rather than perforators
T
With perforator flaps, the anterior rectus fascia can often be closed
primarily.
T
harvest of a horizontal unilateral skin island may distort the midline
F harvest of a vertical unilateral skin island may distort the midline
Latissimus Dorsi flap cannot include bone with it
F including bone based on the angular branch to the tip of
the scapula.
Shoulder function may be impaired with LD flap
T
In the case of thoracodorsal
the pedicle is compromised by previous axillary dissection we canot harvest the L D flap
F thisflap can still
be used by relying on bloodflow through the serratus branch
When used in breast reconstruction, it always requires volume supplementation with an implant
F When used in breast reconstruction, it often requires volume supplementation with an implant
