ObjectiveTo compare operation-specific decannulation rates between single-stage (SSLTR) and double-stage laryngotracheal reconstruction (DSLTR) when controlling for grade of airway stenosis.MethodsA systematic review and meta-analysis were performed using PubMed, EMBASE and Cochrane databases from 1970 to 2015 to examine primary SSLTR and DSLTR for subglottic stenosis in patients 18 years or younger. Primary outcome was decannulation or extubation after LTR. Failures included patients not decannulated or requiring additional open airway procedures prior to decannulation. Only studies providing outcomes delineated by airway stenosis grade were included. Non-English language studies and case reports were excluded.ResultsThere were 712 abstracts reviewed and 16 studies with 663 pooled patients included in the systematic review analysis. The metaanalysis included 5 studies. Overall, the operation-specific decannulation success was statistically significantly different between SSLTR [93.2% (N = 221)] and DSLTR [83.7% (N = 442)] (P<0.001). When controlling for stenosis severity, however, no difference was found in decannulation success between SS- or DSLTR except in the grade 3 group: Grade 1–100% (N = 6) vs. 100% (N = 6), (P = 1); Grade 2 - 84.9% (N = 106) vs. 83.3% (N = 138), (P = 0.72); Grade 3–80.2% (N = 101) vs. 69.7% (N = 238), (P = 0.03); Grade 4–33.3% (N = 6) vs. 50% (N = 58), (P = 0.67).ConclusionNo difference in decannulation rates was seen between SSLTR and DSLTR when comparing similar grades of stenosis except in grade 3 stenosis. With worsening stenosis, the success rate declines with both methods. Prospective studies with standardized enrollment criteria and reported outcomes are needed to better understand the advantages and disadvantages of each approach.
