Objective:
To review the current literature about surgical treatments of pediatric bilateral vocal fold paralysis (PBVFP).
Methods:
A systematic review of the current literature in PubMed, Scopus, and Cochrane Library regarding etiologies and management of PBVFP was performed until November 2023 according to PRISMA statements. Quality assessment was assessed with Methodological Index for Non-Randomized Studies (MINORS) tool.
Results:
Of the 211 screened articles, 26 were included accounting for 320 patients. The etiologies included idiopathic (42.2%), congenital (19.7%), neurological (16.9%), or post-surgical (9.5%) pediatric bilateral vocal cord paralysis (PBVCP). Patients were decannulated in 76.7% of cases without laryngeal procedure. Decannulation was achieved in 84.6%, 66.6%, 83.3%, 80.0%, and 62.5% of cases of laterofixation of the vocal fold, cricoid split approaches, partial or total arytenoidectomy, uni- or bilateral transverse cordotomy, and selective laryngeal reinnervation, respectively. Dyspnea/stridor relief, swallowing, or voice quality outcomes were used in some studies, which reported conflicting results. Revision and complications varied between studies, with complications mainly involving edema, granuloma, or aspirations. Revision was required in 6.4%, 12.9%, and 40.0% of cases that underwent laterofixation of the vocal fold, arytenoidectomy, and cricoid split procedures, respectively. There was substantial heterogeneity across studies in inclusion criteria, procedures, and outcomes.
Conclusion:
The management of PBVFP may involve several temporary or permanent surgical procedures that are associated with overall subjective improvements of symptoms, and laryngeal findings. The retrospective design of studies, the small number of cohorts, the lack of objective outcomes, and the differences between teams regarding procedure timing and features limit drawing reliable conclusions about the superiority of one technique over others.
