Symptomatic Pedicle Ossification Following Fibular Free Flap Reconstruction: Case Report and Review of the Literature

Ossification of the vascular pedicle following fibula free flap (FFF) reconstruction is an uncommon and typically asymptomatic complication. Symptomatic cases requiring intervention are rare. We report a 29-year-old man with anterior maxillary osteosarcoma who underwent tumor resection followed by reconstruction with an osteocutaneous FFF. Calcification within the surgical site region was noted on imaging at two months after fibular reconstruction. By five months, he developed progressive trismus and pain with mastication. Computed tomography demonstrated a calcified structure extending from the mandible to the reconstructed maxilla along the flap pedicle, raising concern for tumor recurrence. Surgical excision was performed, and histopathology revealed benign woven bone without evidence of malignancy. Postoperatively, trismus improved, and flap viability was preserved. Retained periosteum during FFF harvest maintains osteogenic potential and may result in pedicle ossification. In symptomatic patients, particularly when recurrence is suspected, surgical resection is both diagnostic and therapeutic.
