Abstract
ObjectivesTo systematically review the frequency and time to spontaneous recovery in pediatric patients with bilateral congenital idiopathic laryngeal paralysis (BCILP). MethodsThe databases of Medline, EMBASE, Scopus, CINAHL, Cochrane Library and Proquest Dissertations were searched for English language articles reporting on laryngeal paralysis in pediatric patients. A bibliography search of the selected studies was done to identify additional articles. We included prospective or retrospective case-series studies of children and neonates diagnosed with BCILP at age <60 days and confirmed by direct laryngoscopy, with sufficient follow up and objective assessment for recovery.Two authors independently extracted the data and assessed the quality of each study. Discrepancies were resolved by consensus and adjudication by a third author. ResultsOf the 4229 articles identified by the search, only one study met our inclusion criteria. The study was a retrospective case series, and was of low quality. The mean age at diagnosis was fourteen days. Sixty-five percent of the patients recovered spontaneously, and the mean time to recovery was twenty-five months. Tracheostomy was performed in 71% of the patients. ConclusionsThe available literature is of low quality and provides weak evidence on the natural history of BCILP in pediatric population.
