Three types of reconstruction are possible following total laryngopharyngectomy (TLP) for advanced hypopharyngeal cancer: locoregional tubularized island flaps, gastric pull-up and free flaps. Gastro-omental free flap (GOFF) is rarely used in this setting. However, because of its composite nature, this flap has the advantage of being able to restore digestive continuity and reconstruct part of the skin of the neck when it needs to be sacrificed because of tumour invasion or poor trophicity. The GOFF is a reliable and robust flap particularly indicated in hostile environments: repeated neck surgery, atrophic and devascularized skin after radiotherapy, sepsis in the context of fistula and/or pharyngostomy. It requires the collaboration of two or even three surgical teams. In this article, we describe the flap harvesting technique and the complications and functional outcome.
