Abstract
The study goal was to determine the impact of various surgical procedures for bilateral vocal cord paralysis in children by using established principles of meta-analysis.
We conducted a retrospective review of the literature in which a predetermined protocol was used to identify articles for meta-analysis. Six articles met inclusion criteria, and pertinent data were extracted.
Pooled data analysis demonstrated primary procedure-specific decannulation rates for external arytenoidopexy for 19 of 24 (79%), external arytenoidectomy for 14 of 19 (74%), CO2 laser arytenoidectomy for 4 of 10 (40%), and costal cartilage graft procedures for 2 of 2 (100%). External arytenoid procedures are more efficacious than CO2 laser procedures in terms of primary decannulation (P = 0.02).
Meta-analysis of the existing literature reveals that external arytenoidopexy and external arytenoidectomy are equivalently effective procedures and that the two combined are significantly more effective than CO2 ablative procedures.
External procedures appear to be more effective as a first-line treatment in pediatric vocal cord paralysis, with arytenoidopexy with or without partial arytenoidectomy offering an attractive first-line surgical option.
