Prevention of hair growth in myocutaneous flap reconstruction

Myocutaneous flaps play a prominent role in the immediate reconstruction of surgical defects following ablative oncologic procedures in the head and neck. Transfer of hair-bearing skin into the reconstructed upper digestive tract can be a major disadvantage associated with the pectoralis major flap. De-epithelialization of skin to the dermal level, removing the majority of skin appendages, can convert a myocutaneous flap to a "myodermal" flap. Platysma myocutaneous and myodermal flaps were grafted into the oral cavity of 13 dogs. Gross and histologic evaluation confirmed decreased hair growth in the experimental myodermal flap. Wound complications and graft survival were similar for both techniques. Diminished hair growth further supports the utility of myodermal flaps in hairy male patients undergoing upper digestive tract reconstruction.
