The framework of the larynx is formed by the thyroid, cricoid and epiglottic cartilages and by pairs of arytenoid, corniculate and cuneiform cartilages. The aryepiglottic folds and the arytenoids are located immediately behind the epiglottis (Fig. 11.6). The aperture of the glottis (rima glottidis) is formed by the true vocal folds (plicae vocales) and the posterior commissure between the arytenoids. The anterior ligament of the true vocal folds is located at the anterior angle of the vocal folds. Between the true vocal folds and the false vocal folds (vestibular folds; plicae ventriculares) is the laryngeal ventricle. The nodular swellings located medially in the aryepiglottic folds are the corniculate cartilages which sit on top of the arytenoid cartilages. Lateral to the corniculate cartilages are the cuneiform cartilages.

The corniculate cartilages (of Santorini) are two small conical nodules of elastic fibrocartilage, which articulate through a synovial joint with the apices of the arytenoid cartilages. They are situated in the posterior part of the aryepiglottic fold. The cuneiform cartilages (of Wisberg) are two small, elongated flakes of fibroelastic cartilage, one in each free margin of the aryepiglottic fold. The function of these cartilages is uncertain. They may act to provide structural rigidity to the aryepiglottic folds somewhat like curtain weights.

There was no comment on the presence of cartilage in the series by Iyer et al. [7]. Chandra et al. [8] found two out of nine patients in their study having resected specimens containing fibrocartilage. These were deemed to be the cuneiform cartilages. In their opinion, the malacic collapsing component of the larynx is usually the posterior supraglottic larynx, including the cuneiform cartilages and thus cuneiform cartilages are excised as part of the aryepiglottoplasty when necessary [8]. The majority of the specimens, 47 (77%) cases in our study contained cartilage, having said that, the operating surgeon judges the amount of prolapsing tissue to resect and does not set out to necessarily resect cartilage, removing the mucosa in the region of airway prolapse with contained cartilage if required. Cartilage immaturity has been implicated as a cause of laryngomalacia [8]. Out of the 47 cases with specimens containing cartilage, over half (59.6%) had immature cartilage. This gives some weight behind the theory of a chondropathic component in laryngomalacia.
Anterior glottoplasty: the effect of inclusion of the vocal fold lamina propria to frequency elevation

The epiglottis, cuneiform cartilages, corniculate cartilages, and ventricular folds as well as the superior cornu were dissected away to expose the true vocal folds. A segment of trachea was preserved and sealed off by the inflated balloon of the endotracheal tube. The humidified and compressed air was provided by a ventilator (ResMed AutoSet II, Australia) and passed through an airflow adjust controller and a flowmeter (MF5706-N-10, Siargo Ltd, Shanghai, China) which was connected to the endotracheal tube. Vocal fold adduction was achieved by 5-0 polypropylene sutures placed through the vocal process and arytenoid cartilage (Figure 1(A)).
