S147 – Pectoralis Major Flaps: A Workhorse in Today's Free Flap Era

Abstract

Objectives To study the use, complication rate, and efficacy of pedicled local regional flaps for head and neck reconstruction, and to compare these results with those of microvascular free flap reconstruction. Methods Retrospective analysis of all head and neck oncologic resections requiring flap reconstruction in a tertiary head and neck surgery centre over a 6-year period from 2001–2007. Results In total, 77 operations with flap reconstruction were performed. 44 resections employed pedicled locoregional flaps, comprising 33 pectoralis major, 3 trapezius, 3 cervical rotation, 1 deltopectoral, 1 temporalis muscle, 2 nasolabial, 1 cheek rotation, and 2 bilobed rotation flaps. 2 patients had a combination of 2 regional flaps. There was 1 flap failure. Minor complications occurred in 25% of patients comprising wound seromas (3), wound dehiscence (6), fibrotic band formation (1) and pharyngocutaneous fistula (1). 33 resections employed free flap microvascular reconstructions, comprising 22 free radial forearm, 7 free rectus abdominis, 1 free jejunal, 1 free fibular, and 2 anterolateral thigh flaps. There was 1 flap failure. Minor complications occurred in 33% of patients, comprising donor site wound dehiscence (4), recipient site wound dehiscence or seroma (4), plate extrusion (1), abscess and wound breakdown (2). Conclusions Despite the ready access to free flap reconstruction today, pedicled flaps, especially the pectoralis major flap, remain a major workhorse in head and neck reconstruction. They are hardy, reliable, cost-effective, and can be done in a short operative time. Moreover, for several regions, the functional outcome is no worse than free flap reconstruction.
