Particular attention was paid to the subglottic region, where previous studies have reported areas of squamous metaplasia in neonates, infants, and nonsmoking adults. Both types of epithelium were found in different proportions in the supraglottic, glottic, and subglottic regions. There was considerable downward extension of squamous epithelium from the glottis into the subglottic region, with a wide transition zone where both types of epithelium were found in close association. These observations would suggest that such areas of squamous epithelium in the nonglottic larynx are normal, rather than always indicating a response to extrinsic trauma or irritation. Therefore, the term squamous metaplasia may be inappropriate when applied to such areas in the adult larynx.<\/jats:p>","DOI":"10.1177\/000348948809700319","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:35:41Z","timestamp":1412346941000},"page":"302-307","source":"Crossref","is-referenced-by-count":3,"title":["Epithelial Distribution in the Human Fetal Larynx"],"prefix":"10.1177","volume":"97","author":[{"given":"Nicholas D.","family":"Stafford","sequence":"first","affiliation":[{"name":"London, England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen J.","family":"Davies","sequence":"additional","affiliation":[{"name":"London, England"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1988,5,1]]},"reference":[{"key":"bibr1-000348948809700319","first-page":"250","volume":"2","author":"Toumeux MF","year":"1885","journal-title":"C R Soc Biolog Paris"},{"key":"bibr2-000348948809700319","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-195507000-00001"},{"key":"bibr3-000348948809700319","doi-asserted-by":"publisher","DOI":"10.1177\/00034894760850S501"},{"key":"bibr4-000348948809700319","doi-asserted-by":"publisher","DOI":"10.1007\/BF01884435"},{"key":"bibr5-000348948809700319","doi-asserted-by":"publisher","DOI":"10.1007\/BF01942419"},{"key":"bibr6-000348948809700319","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2273.1980.tb00910.x"},{"key":"bibr7-000348948809700319","unstructured":"Bremer JL.
