For mucosal ablation, vocal quality recovered 1 month after surgery. For mucosal stripping, although vocal quality was steady 3 months after surgery, slight hoarseness persisted in this group. The contour of the treated fold recovered postoperatively. There were no complications in recovery. For cordectomies, vocal quality became steady 6 months after the surgery. The supraglottal hyperfunction with supraglottal structure squeezing played an important role in phonation. The affected vocal fold mucosal wave was absent instead of a regular ventricular fold wave or mucosal wave of the vocal process during phonation. In comparison with the type III-IV cordectomy, the results of extended cordectomies (type Va and Vc) were worse; however, the difference was not statistically significant. Granulomas and anterior commissure webs were present. All granulomas resolved spontaneously 3 months postoperatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
