Cysts of the larynx — classification.

Congenital laryngeal saccular cyst: a case report and literature review

“…This obstruction can be caused by the abnormal migration of the tissue from the fourth branchial arch generating the cystic formation (14) or by the isolation of the cells of the sac due to the abnormal migration of mesenchymal cells through persistent fetal vessels in the larynx. The second may be a consequence of sac obstruction secondary to neoplasia, trauma or inflammation with subsequent fibrosis (15).…”

“…Several authors state that diagnostic confirmation is achieved through direct visualization of the lesion, either by direct or optical fiber laryngoscopy (17,15), as described here.…”

Oncocytic variant of a ductal retention cyst in the interarytenoid region

“…A revised classification into ductal and saccular cysts was made based on location and depth of the cyst in the larynx 5 . Newman et al created a modified working classification dividing laryngeal cysts into epithelial cysts with or without lymphoid tissue, tonsillar cysts and oncocytic cysts 6 .…”

“…it was noted that epithelial cysts were more common, tonsillar cysts tend to be multiple and oncocytic cysts occurred in the older age group 7 . Most of the series of laryngeal cysts include vallecular cysts 5,6,7 . The vallecula is a region described in the oropharynx.…”

Cisto sacular congênito da laringe

“…It may be congenital or acquired. Acquired cases may have their origins in prolonged orotracheal intubation or laryngeal surgery 1 . Laryngeal saccular cysts are among the causes of laryngeal stridor in neonates and make up the differential diagnosis roster against laryngomalacia, vocal fold paralysis, congenital subglottic stenosis, laryngeal web, and laryngocele 2 .…”
