Ventricular or Other Laryngeal Cysts

Case 1: Newborn with airway obstruction found to have right ventricular cyst at endoscopy. Following CT scan, operative removal via vertical laryngofissure revealed duplication cyst pathologically.

Figure 2. CT demonstrated extralaryngeal cyst.

Figure 5. Vertical laryngofissure revealed large cyst, excised completely.

Figure 6. Laryngofissure closed. Patient successfully extubated after short period of intubation.

Figure 7. Microscopy showed respiratory epithelium, with mucous glands surrounded by cartilage (Figure 8).

Figure 8. This pathology suggested a duplication cyst of the larynx.

Case 2: 4 month old (corrected age) with long term intubation in the neonatal period for prematurity persistent stridor since extubation. Endoscopy revealed intubation retention cysts.
