Squamous Carcinoma of the Oral Cavity in Patient with Fanconi Anemia: A Challenging Reconstruction with Double-barrel Free Fibula Flap Case Report.

Fanconi anemia (FA) is a very rare form of aplastic anemia. Patients with FA have a higher risk of developing solid tumors such as head and neck squamous cell carcinoma, higher risk of local recurrence, and impaired resistance to chemotherapy and radiotherapy treatments than the normal population. In this article, we describe the challenging clinical case of a patient with FA who underwent surgery for the removal of a large squamous cell carcinoma in the oral cavity. Mandibular reconstruction was performed using a biaxial double-barrel fibular flap, with excellent functional aesthetic outcomes.
