Complication After Mandibular Reconstruction With Fibula Free Flap in a Patient With Hemifacial Microsomia.

ABSTRACT: Hemifacial microsomia is the second most frequent pathology in craniofacial malformations. Clinical findings are broad, mainly affecting the mandible. Several classifications of mandibular compromise exist that guide the best treatment option in each patient. The authors present a case of an unusual complication following fibular free flap mandibular reconstruction in a patient with hemifacial microsomia prada type IV, who presented with ankylosis at the skull base and simultaneous fibula pseudoarthrosis at the union with the residual mandible. These dual findings allowed the patient to have a functional mouth aperture, which give us time to let him grow and wait for final management. Treatment options and follow up are discussed, knowing that there is no literature to support any protocol with this patient, so we present his evolution.
