Both early and advanced stage laryngeal cancers are treated with organ-preserving strategies including radiation alone or concurrent chemoradiotherapy. While organ-preserving modalities have proven effective in eradicating cancer while also preserving laryngeal function, there remains a proportion of cases where residual or recurrent cancer prevails, or conversely, where radiotherapy renders a larynx dysfunctional. In these circumstances, salvage total laryngectomy is often the surgical treatment. The effects of radiotherapy to the neck, amplified by chemotherapy, can create an inhospitable surgical environment, making the salvage laryngectomy an operation fraught with the potential for major complications such as the dreaded pharyngocutaneous fistula.The introduction of vascularized tissue from outside the irradiated field decreases the risk of major wound complications. Free tissue transfer, with a variety of donor sites available, is commonly employed to reconstruct either a patch or a circumferential segment of the pharynx. When there is enough pharyngeal mucosa for primary closure, a vascularized onlay graft or a pharyngeal interposition graft can be used to reinforce the closure. This has been demonstrated to both reduce the severity of pharyngocutaneous fistula and decrease the risk of developing a pharyngocutaneous fistula compared to primary closure alone.Beyond mitigating the risk for perioperative complications, flap selection may have implications on the long-term outcomes after salvage total laryngectomy and these must be considered preoperatively. The purpose of this review is to examine the various options for reconstruction after salvage total laryngectomy and to examine some of their advantages and disadvantages in the short and long-term.
