%X Introduction: Pectoralis major myo-cutaneous (PMMC) flap continues to be a widely used tool to reconstruct oral cavity defects. But an unreliable and unstable vascular supply can lead to complications like flap loss, Oro-cutaneous fistula and wound dehiscence. Preservation of the lateral thoracic artery (LTA) has been suggested to improve the vascularity of the skin paddle. The present study aspires to compare the complications and flap related outcomes after preserving or sacrificing the LTA while reconstructing oral cavity defects with bi-folded PMMC flap. Materials and Methods: Retrospective analysis of the data of 61 male patients who were reconstructed with bi-folded PMMC flaps between January 2022 and September 2022 was done. 36 patients were reconstructed using a PMMC flap where the LTA was sacrificed, whereas in 25 patients the LTA was preserved. Data was analyzed in terms of patient factors and flap related complications. Results: The overall complication rate including major/minor complications was 44.26% with flap detachment at 22.95% being the commonest complication observed. 13.11% patients developed an Oro-cutaneous fistula and partial and complete flap loss were seen in 9.83% and 4.91% respectively. LTA preservation was significantly associated with only decreased flap detachment rates (p value < 0.05). No significant association was noticed between other flap related complications and LTA preservation. Conclusion: Reconstructing larger defects with a PMMC flap where the LTA is preserved can help improve the vascularity of the flap and decrease various major/minor flap related complications.
