Reconstruction of oncological oro-mandibular defects with double skin paddled-free fibula flap: A prudent alternative to double flaps in resource-constrained centres

摘要

Objective: The free fibula flap is the choice flap for mandibular reconstruction following extensive tumor resections. While large defects are managed with a second flap [free or pedicle] in advanced centres, a free fibula flap with a large skin paddle that can be de-epithelised to provide outer skin and inner lining is the best alternative in resource- constrained centres. Materials and Methods: From January 2005 to December 2009 a total of 386 free fibula flaps were used of which 307 flaps had de-epithelised double skin paddle in reconstructing complex oral and mandibular defects after tumor ablative surgeries. Results: Complete flap survival was seen in 282/307 patients. Complete flap loss was seen in 9/307 patients. Partial flap loss was seen in 16 patients. Re - exploration was done in 30 patients and the flap was salvaged in 21 patients. Conclusion: The vascular supply of the free fibula osteo myocutaneous flap is reliable and a flap with a large skin paddle can be used to provide both inner lining and outer cover in resource-constrained centres.
