ves·tib·u·lar fold

one of the pair of folds of mucous membrane overlying the vestibular ligaments that stretch across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; the right and left pair enclose a space called the rima vestibuli or false glottis, and form the superior boundary of the laryngeal ventricle.

According to Bak-Pedersen and Nielsen (1986), vestibular folds play a fundamental role in the lubrification mechanism of the laryngeal epithelium, since the number of subepithelial glands found in this fold was greater (128 gland/ cm3) in comparison with the vocal fold (13 gland/[cm.sup.3]).
The vestibular folds obtained from six larynxes were submitted to the usual histological techniques, and cut into 7 [micro]m-thick sections transversal to the larger fold axis.
The vestibular folds of the ten larynxes were removed from the laryngeal cavity and reduced to fragments, which were individually immersed in -160[degrees]C liquid nitrogen using tweezers.
Ten [micro]m-thick serial sections were obtained from the medial portion and transversally to the larger axis of the vestibular folds.
