There are two important things to consider when reconstructing swallowing function in cases of hypopharyngeal cancer and laryngeal cancer: that there is no defect in the structure that separates the airway and food, and that there are no obstacles in the flow path of food. Based on this idea, we developed a new surgery that can preserve laryngeal function in patients with advanced laryngeal cancer. All three patients have survived disease-free for more than 36 months after tumor resection, and laryngeal function is maintained. This surgery is routine and can be standardized, and future studies may show that it is a potential option for preserving the larynx in cases of advanced laryngeal cancer with vocal cord paralysis. We also examined 33 cases of hypopharyngeal cancer patients who underwent reconstruction by free tissue transplantation for partial hypopharyngeal laryngectomy. Regarding the morphology around the larynx after reconstruction, it was shown that it is important to secure a food channel outside the larynx.
