Background: The objective of this study was to prove that there is no significance to the donor side (right or left) of the free fibula osteocutaneous flap (FFOCF) in the reconstruction of complex oromandibular defects (COMD) and proper flap planning, designing and tailoring are important in reconstructing different types of COMD after tumour-ablative surgery.
Materials and methods: Three hundred and eighty-six consecutive patients who where reconstructed with FFOCF for COMD from Jan 2005 to Dec 2009 over a period of 5 years were studied. Except in seven patients, all fibula flaps were harvested from the left leg as per convenience and to facilitate a simultaneous, two-team approach. Depending on the condition of the neck vessels, vascular anastomosis was performed on the right or the left side, irrespective of the side of the defect.
Results: Complete flap survival was seen in 334 patients (86.52%). Superficial skin necrosis was seen in 20 patients, and was managed conservatively (5.18%). Partial flap loss was seen in 20 patients (5.18%). There were 39 re-explorations. Complete flap loss was seen in 12 patients (3.10%).
Conclusion: We found no significance in terms of the results as far as the side of flap donor leg or primary defect were concerned. Flap tailoring in terms of meeting the tissue requirement and vessel orientation were rather more important.
