Background: Reconstruction of complex head and neck defects is challenging, especially when more than one soft-tissue subunit is involved. The osteocutaneous fibular flap underwent continual evolution to improve its soft-tissue characteristics, such as including a second skin island. The purpose of this study was to evaluate outcomes regarding oromandibular reconstruction with a double-skin paddle fibular free flap (DSPFFF) using three different techniques: central de-epithelialized skin paddle, distally-based double-skin paddle (DSP), or proximally and distally-based DSP.
Methods: A systematic review was performed in December 2020 using Pubmed and MedLine Ovid databases according to the PRISMA guidelines. A meta-analysis of functional outcome and complications was performed to estimate single incidence rates.
Results: A total of 449 patients were included, with a follow-up of 1-84 months, where 330 patients underwent reconstruction with the first technique, 23 patients with the second technique, and 96 patients with the third technique. The meta-analysis showed an overall good functional outcome and a low-complication rate for oromandibular reconstruction with DSPFFF. A better functional outcome and a lower complication rate were found when a distally-based DSPFFF was harvested compared to a proximally and distally-based DSPFFF.
Conclusion: The DSPFFF was found to be useful and reliable for reconstructing composite and extensive head and neck defects, with an overall good functional outcome and a low-complication rate. The meta-analysis showed a better positive outcome on distally-based DSPFFF rather than proximally and distally-based DSPFFF. In addition, distally-based DSPFFF showed a lower complications rate when compared with proximally and distally-based DSPFFF.
