Using a Free Ileocolic Graft Hideyuki Kawahara 1), Takeshi Shiraishi 2), Yasunori Yoshida') and Takayuk Shirakusa 2) A technique for surgical voice restoration using a free ileocolic graft is presented. In this technique, a phonatory T-C (tracheocolic) shunt was fashioned from the terminal ileum. The sphincteric function of the ileocecal valve eliminated salivary leakage into the trachea. This valve mechanism was reinforced by the extrinsic compression produced by the "cecal application. " The
