Glottic web

An abnormal, continuous sheet of mucosa that joins the vocal cords together. This glottic web is analogous to the web one sees between adjacent fingers. Normally, in the absence of a glottic web, the mucosa covers each vocal cord individually to form a crisp “V”.

A glottic web may be congenital, or it may result from injury. Classic teaching is that surgeons ought not to operate on the anterior portion of both vocal cords simultaneously, because the raw, de-epithelialized surfaces may grow together and create an anterior glottic web. Some webs do not need to be addressed because the effect on voice is minimal; in other cases, surgical approaches are indicated because of the poor voice often associated with this abnormality.
