    Notes: Abstract The normal topographic relationships of the anterolateral surface of the arytenoid cartilage (ALSAC) were reinvestigated with special regard to possible implications involving the extensions of local cancer. Serial plastinated whole-organ sections of 34 normal adult larynges were examined. A cartilaginous crest subdivided the ALSAC into a cranial triangular fossa and a caudal oblong fossa and provided attachment to the lateral fibers of the vocal cord. The thyroarytenoid muscle was mainly anchored within the oblong fossa, but a few lateral muscle fibers extended further cranial ward along the ALSAC. The triangular fossa was the area of fixation of the vestibular ligament and was filled with adipose tissue as well as mucous glands grouped together by strong collagenous fiber septa. These septa revealed a craniocaudal orientation medially and a horizontal anteroposterior orientation laterally. These findings suggest that the septa guide early local cancer extension parallel to their own arrangement, acting as barriers that cannot be easily crossed. Correspondingly, cranial and horizontal-lateral cancer spread along the ALSAC has been reported in the clinical literature.

    Borders and topographic relationships of the paraglottic space (1997)

    Notes: Abstract The precise topographic relationships of the paraglottic space (PGS) were investigated in serial plastinated or frozen whole-organ sections of 46 normal adult larynges. Laterally, the PGS was bordered by the thyroid cartilage. Superomedially, the PGS in some specimens was only separated from the periepiglottic space by a coherent collagenous fiber septum. The paraglottic adipose tissue extended between the caudal fibers of the thyroarytenoid muscle. Inferomedially, the PGS was bordered by the conus elasticus. The anteroinferior portion of the PGS extended beyond the larynx beneath the inferior rim of the thyroid cartilage. Posteroinferiorly, the paraglottic adipose tissue extended towards the cricoarytenoid joint. Dorsally, the PGS was bordered by the mucosal lining of the piriform sinus. Due to the intimate topographic and histologic relationships present, cancer involving the PGS may rapidly infiltrate all adjacent anatomic structures.
