Bilobed platysma myocutaneous flap in reconstruction of mandibular region cutaneous defect

Reconstruction of large cutaneous defects is a challenging task for plastic surgeons. when the skin defect is only part of the complex defects after expansion resection of oral cancer and neck dissection should be done at the same time,it is a daunting task to obtain a cosmetic post-operative appearance. we designed bilobed platysma myocutaneous flaps to reconstruct the mandibular region cutaneous defects. and at the same time,the incessant of the bilobed flap can be a combined incision of platysma myocutaneous flap and neck dissection and can be used to expose fully the region of neck dissection and to supply a large enough platysma flap to reconstruct the mandibular skin defect. this design has several advantages and worth to be promoted.
