抄録

Residual larynx tissue after SCHLP was obtained from a patient with hypopharyngeal cancer, who had suffered multiple recurrences. Two and three-dimensional histopathological studies were conducted using serially sectioned whole laryngeal specimens. The inner surface of musculoperichondrial flap was newly epithelialized by ciliated columinal epithelium. Multiple cartilaginous fragments were observed beneath the epithelium surface. The inner space of the residual larynx was wider at the false vocal fold and the arytenoid level rather than at the vocal fold level. This suggests that the false vocal fold and the arytenoid have important roles in phonation after SCHLP.
