Composite pronator quadratus: radial forearm free flap in functional lip reconstruction.
ANZ Journal of Surgery 2019 July
BACKGROUND: Reconstruction of lip defects following neoplasia and trauma is a common procedure in plastic surgery. Reconstruction of large lip defects is a difficult undertaking and some degree of residual functional impairment and disability are likely to occur. Microsurgical reconstruction is the recommended technique for large lip defects; however, limitations exist regarding optimal aesthetic and functional outcomes with current free flap options.
METHOD: We propose a new composite flap design based on the innervated pronator quadratus with the radial forearm free flap for a more dynamic reconstruction of total or near total lip defects. Results of our series of four patients have been reviewed.
RESULTS: The radial forearm flap - innervated pronator quadratus flap has been used in four patients thus far for lip reconstruction. This flap, in our limited series has shown excellent results in achieving oral competence, good motor function and acceptable cosmetic appearance.
CONCLUSION: The composite radial forearm-pronator quadratus flap is a promising new lip reconstruction technique that has potential to provide a higher level of oral competence, sphincteric function and symmetrical lip movement, than current microsurgical options in dynamic lip reconstruction. This method warrants further investigation in plastic surgery literature.
