SCPL is a surgical procedure in which the thyroid cartilage and true and false vocal folds are resected while preserving at least one arytenoid cartilage. There are two types of SCPL.
A normal-appearing cricoarytenoid joint was defined as one with a clearly visible soft-tissue plane between the articular surface of the cricoid cartilage and the surface of the arytenoid cartilage on two or more orthogonal planes, with homogeneous density of the cartilage (figure 1).
proposed this procedure in 1984.[2] Endoscopic laser surgery had commonly been used but could result in the formation of granulation tissue leading to renarrowing of the airway or excessive enlargement of the glottic lumen which was irreversible.[3] Most of the laser surgery actually ablated partial arytenoid cartilage, large proportion of vocal ligament, and the thyroarytenoid (TA) muscle to achieve enlargement of the glottic lumen.[3],[4],[5] The cricoarytenoid joint (CAJ) and CAJ fixation (CAJF) were often developed after the first session of laser surgery.
(20) This should be distinguished from cricoarytenoid joint luxations, which are characterized by displacement (anterior, medial, posterior, etc.) of the arytenoid cartilage, often with accompanying rotation or tilting of the cartilage with respect to the cricoid.
Asymmetric thickening of the vocal cord on the left side, dilated left pyriform sinus and left laryngeal ventricle, and anteriomedial deviation of the arytenoid cartilage were illustrated.
The supraglottic index (SGI) uses a scale to score for the presence of edema and erythema /hyperemia in the epiglottis, false vocal cords, and arytenoid cartilage, as well as secretions or mucosal thickening of the piriform recess and posterior commissure.
It contains the epiglottis, arytenoid cartilage, aryepiglottic folds, vocal cords and the cricoid cartilage.
Stroboscopic examination revealed a solid mass lesion, 10 x 10 mm in diameter, on the left arytenoid cartilage (figure 1).
Procedures on arytenoid included extralaryngealarytenoidectomy (4) in which arytenoid cartilage was freed from all its muscular and laryngeal attachments except the vocal muscle.
Then, a modified posterior ML with a larger prosthesis projected toward the vocal process was placed to medially displace the vocal fold and arytenoid cartilage simultaneously.
It refers to partial displacement of the arytenoid within the cricoarytenoid joint, as distinct from arytenoid dislocation, which is complete separation of the arytenoid cartilage from the joint space.
She subsequently reported to an emergency department, where computed tomography (CT) demonstrated soft-tissue edema without laryngeal pathology or arytenoid cartilage dislocation.
