Illustration of the surgical procedure for vocal fold implantation in the rat model. (A) A rat was secured on a customized surgical platform in supine position. (B) The rat larynx was visualized with a surgical microscope through a 4.0-mm otoscope specula. (C) Superior view of the rat larynx through the surgical microscope (top: anterior; bottom: posterior). (D) A wound was surgically created by a 1-mm long longitudinal incision on the superior surface of the left, posterior vocal fold (arrow) and two bovine acellular scaffold samples were implanted into the wound. No wound was created on the contralateral (right) vocal fold for this particular rat, but wounds were created on the right vocal fold as control in 20 rats. (E) 24 hours following surgery, the vocal fold implanted with the scaffolds (arrow) appeared normal (AC = arytenoid cartilage)
