Abstract

Most of the time, discovery of free flap pedicle calcification is fortuitous. We describe this phenomenon, try to elucidate its consequences, and discuss about prevention. We studied the effect of radiotherapy on the onset of calcification. We describe the first case of pedicle calcification with a scapula free flap. We performed a retrospective study among the 162 bony free flaps harvested from 2003 to 2011. Follow-up included clinical examination, radiography, and head and neck computed tomography. We collected data including patients' age during free flap surgery, genre, primary disease, disease location, connected artery, ossification delay, clinical signs, flap vitality, and, eventually, calcification removal. We tested the effect of radiotherapy on the onset of calcification using a log-rank test. We retrieved data of 15 patients with pedicle ossification after bony free flap (9.2%). Fibula free flap was present in 14 patients and scapula free flap was present in 1 patient. We noticed vascular pedicle ossification in 42% of our maxillary reconstructions and in 7% of our mandibular reconstructions. The maxillary-to-mandibular ratio is 5:10. Pedicle ossification was discovered between 92 and 366 days after surgery. We perfo...Continue Reading
