Microdebrider resection of bilateral subglottic cysts in a pre-term infant: a novel approach

Acquired subglottic cysts are a rare cause of stridor in infants. The two major risk factors for development of these cysts are prematurity and history of intubation. Microlaryngeal decompression and carbon dioxide laser resection of these cysts have been the most common treatment methods with recurrence rates as high as 43% [J. Lim, W. Hellier, J. Harcourt, S. Leighton, D. Albert, Subglottic cysts: the Great Ormond Street experience, Int. J. Pediatr. Otorhinolaryngol. 67 (2003) 461-465]. Carbon dioxide laser therapy also carries the risk of airway fire, injury to adjacent structures, and possible delayed scarring. We present a case of bilateral subglottic cysts in a premature infant with progressive stridor, treated using a microdebrider, and review the literature regarding the treatment of these lesions.
