Procedure
The first stage of the surgery was completed without
difficulty. The necrotic tissues were debrided until
healthy tissues were found. The maxilla, malar, and or-
bital rim were reconstructed in the traditional fashion
using titanium implants to reduce the fractures. The
avulsive defects were then packed and we returned to
the OR a few days later to complete the reconstruction.
A fibular free flap was harvested to reconstruct his
mandible, and the soft tissue skin paddle from the leg
was used to reconstruct his floor of mouth and ventral
tongue. Simultaneously, a second free flap was taken,
and the radial forearm free flap was used to reconstruct
the avulsed soft tissues of his neck and chin. Both free
flaps were anastomosed to an artery and vein in the
neck measuring 2-3mm in size, using a microscope
and 9-0 nylon sutures to supply these large tissue flaps
with their own blood supply. At this point, the patient’s
initial surgeries were completed. His wounds were
closed and he was stable. He was able to eat and talk,
however, he would require additional surgeries.
He was returned to the OR several times over the past
3 years to reconstruct the remainder of his face. His
right maxillary defect was initially attempted to be re-
constructed using non vascularized iliac crest, how-
ever, this bone graft failed, ultimately requiring another
fibular free flap for reconstruction of his anterior and
right maxilla. This was successful in reconstructing his
maxilla and prepared him well for dental implants. In
addition, a serial excision technique was used to ad-
vance the cervical soft tissues to replace the trans-
planted tissues with native tissue to create better
symmetry. In addition, his lower lip was reconstructed
using mucosal advancement flaps.
Results
With the ability to reconstruct patients using microvascular free tissue transfer, even large
defects that in the past were unimaginable, can be reconstructed with excellent results.
Although this patient was financially unable to complete dental rec onstruction, his quality of
life has returned to a very high level. He can eat nearly anything he wants, and can speak,
and truly appear normal to those that do not know what he has been through.
