This study investigates the structural organization of the VF microanatomy across gender and age groups using optical coherence tomography (OCT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Prospective clinical trial.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p><jats:italic>In vivo<\/jats:italic> OCT images were acquired from 97 patients (58 males and 39 females) aged between 6\u2009weeks and 27\u2009years. All patients showed no signs of vocal fold pathology on endoscopy. Morphological features were extracted from OCT images and statistically compared between age groups. This study was performed at Massachusetts Eye and Ear between 2017 and 2019.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All OCT acquisitions show a stratified microanatomy across age groups, even in newborns suggesting the presence of a superficial lamina propria (SLP) at birth. Furthermore, the optical scattering in the VF lamina propria changes according to age, suggesting subepithelial maturation. Although the epithelium thickness was relatively constant across age groups, the SLP showed a significant linear relationship between age and thickness (<jats:italic>P<\/jats:italic>\u00a0=\u2009.016). Furthermore, a significant difference (<jats:italic>P<\/jats:italic>\u00a0=\u2009.002) in SLP thickness was found between young adult males and females. The overall thickness of the entire mucosa did not change significantly with age.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>OCT is a noninvasive imaging modality capable of providing quantitative morphological features to describe the VF development. A stratified structure can be observed in OCT from newborns to young adults. Further investigations could combine OCT, acoustic measurements, and molecular sensitive techniques to provide a complete interpretation of the VF development.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>NA <jats:italic>Laryngoscope<\/jats:italic>, 131:E2558\u2013E2565,
