The use of myocutaneous flaps in block dissections of the groin in cases with gross skin involvement.

Various myocutaneous flaps (upper sartorius, upper gracilis and lower rectus abdominis) have been used in a series of 17 block dissections of the groin with gross skin involvement. Only one of these flaps developed appreciable necrosis. The sartorius flap is restricted in its application for anatomical reasons. The rectus abdominis flap can only be used from the opposite side in unilateral cases, though it does appear to be the most dependable flap. The gracilis flap appears to be the most suitable for the majority of the patients who usually present with bilateral involvement of the lymph nodes and skin.
