title: Morphology of the human larynx. II. The subglottis.
abstract: The macroscopic staining method was used to display and measure the epithelium of the human subglottic space. Small islands of squamous metaplasia were found in about 40% of the non-smoking, non-bronchitic urban population. There was no age or sex difference, although a highly significant decrease in size of the subglottic space was found in women throughout life.
