목적: This study aimed to evaluate the outcomes of laryngotracheal reconstruction (LTR) in pediatric patients with moderate to severe combined subglottic and posterior glottic stenosis. 방법:Medical records of 11 children (mean 3.2 y.o., range 0.3-6.1 y.o.) were reviewed, who received LTRs including anterior posterior cricoid splitting (aCS, pCS), rib cartilage graft (CG), or cricotracheal resection (CTR) with thyro-tracheal end to end anastomosis. Total 24 LTRs were performed for these 11 patients. The severity of subglottic stenosis were 33.3%, 54.2%, and 12.5% of grade II, III, and IV (by Myer-Cotton), respectively. Four percent, 21%, 21%, and 54% of postglottic stenosis were classified as class I, II, III, IV (by Bogdasarian & Olson), respectively. Outcomes of each LTR were evaluated. Factors influencing the outcome of LTR were analyzed. 결과:Among 24 LTRs, CTR was performed in 2 (8%), aCS in 5 (21%), aCS with CG in 3 (13%), aCS & pCS with CG in 14 (58%). Successful decannulation was possible in 8 (33%) out of 24 LTR procedures, while additional LTR was required in 13 (55%). In overall, 8 of 11 patients (73%) resulted in successful decanulation. Sex, severity of stenosis, types of LTR, single or two-staged operation, and days of postoperative intubation did not influence to the outcome of surgery. However, age at the time of LTR was sigficantly older in successful decannulation group (7.74.4 vs. 3.92.3, P = 0.009). 결론:Successful decanulation was possible in 73% of pediatric patients with moderate to severe combined subglottic and posterior glottic stenosis. Age at the time of LTR was a significant factor for the successful outcome.
