(2) This technique is based on resection of soft tissue and transection of conus elasticus
. A C-shaped wedge of posterior vocal fold is excised beginning from the free border and extending to about 4mm laterally.
(1) The AC tendon represents a confluence of the vocal ligament, the thyroepiglottic ligament, the conus elasticus
, and the internal perichondrium of the thyroid ala.
Proper injection results in placement of the appropriate volume of material into a space bordered medially by the conus elasticus
and laterally by the ala of the thyroid cartilage.
Subglottic neoplasms enter early into the paraglottic space and spread within the region bounded medially by the conus elasticus
and laterally by the hyaline laryngeal cartilages.
