Bipaddle Pectoralis Major Myocutaneous Flap for Single Stage Reconstruction of Oromandibular Defects.

Abstract

Reconstruction of full thickness defects after resection of oral cancer is a challenge. Although microvascular free flaps are considered the first choice, their use is limited in the developing regions by availability of resources and the expertise. In this study, we have presented our experience with the use of bipaddle pectoralis major myocutaneous (PMMC) flap as a single stage reconstruction option for defects of the oral cavity. After undergoing resection of oral cancer, 12 patients with full thickness defects of the oral cavity were reconstructed using bipaddle/bilobed/double-island/folded PMMC flap in a single stage procedure. The results of PMMC flaps were studied. All the patients had through and through defects of oral cavity, which were reconstructed in a single stage surgery using bipaddle PMMC flap. The overall complication rate was 33.33%, however, there were no cases of total flap necrosis. The mean time of reconstruction was 141.25min with average hospital stay of 18.5days. PMMC flap is a versatile flap with dedicated blood supply, good bulk and great reach. With limited availability of resources, it can be used as a single stage reconstruction technique in oral cavity defects with good results.
