Abstract
Posterior glottic stenosis (PGS) is a rare but well-recognized condition that has been classified into 4 subtypes by Bogdasarian and Olson.1 Although PGS is often seen in conjunction with subglottic stenosis, it also occurs as an isolated condition. The cause is usually attributed to prolonged intubation.2-4 At present, there is no consensus as to optimal management, and a broad range of treatment modalities have been proposed, including endoscopic techniques such as laser to the posterior glottis,4-6 laser with cord lateralization,7 laser with botulinum toxin,8 laser with mitomycin C,9 and posterior mucosal advancement flaps,10 as well as open techniques such as buccal mucosal grafting11 and posterior costal cartilage grafting.3,12-14 To date, studies have comprised patients with concomitantly occurring PGS and subglottic stenosis and have not specifically addressed the management of pediatric patients with isolated PGS. Thus, our objective was to present our experience with this condition, using posterior cricoid grafting as a management technique.
