Abstract
The association between the macroscopic configuration and voice function was examined in glottic carcinoma. Glottic carcinoma was classified into four groups based on the macroscopic configuration. The (1) flat type, (2) mass type, (3) papilloma type and (4) submucosa type. The comparison revealed the flat type to be significantly better than the mass type and papilloma type in the sound analysis value and MPT. In addition, no meaningful difference was observed between the groups with regard to the clinical stage. Therfore, the sound of glottic carcinoma was not determined by the clinical stage but by the macroscopic configuration.
