ABSTRACT
In cases of facial asymmetry with denervation atrophy of the masticatory muscles associated
with head and neck tumors involving the trigeminal nerve, facial contour depression
occurs selectively over the temple and masseteric area, separated by an uninvolved
area over the zygomatic arch. The authors developed a new thoracodorsal artery perforator
flap with two separate adiposal paddles based on their own perforators from the same
mother vessel, the thoracodorsal vessel. Nearly normal temporo-masseteric contour
was achieved in two patients. By freely positioning two adiposal paddles supplied
by independent perforators based on the same vessel, separate non-contiguous regions
of the face could be reconstructed correctly with one microvascular anastomosis in
a single-stage operation, without the need for a secondary procedure to reduce the
bulk over the zygomatic arch.
