We gathered wet examples of new cadaveric heads from the Han Chinese adult population for applied life systems of the submental island fold, and followed five patients with pyriform sinus carcinoma after recreation medical procedure utilizing submental island flaps. We tracked down that the normal length and width of the submental island folds were (65.2011.69) mm and (46.706.59) mm, individually. The skin fold in each of the five patients survived after medical procedure, and tracheal cylinders and gastric cylinders were taken out 7-36 days after sur-gery. Patients were followed up for 24 to 42 months, pharyngeal folds developed well, and speechand gulping capacities were good.
