Pediatric Vocal Fold Paralysis

Abstract

Recovery after an interval of up to 11 years was seen in idiopathic bilateral VFP; this has significant implications when considering lateralization procedures in these patients.

Paralisia de prega vocal em crianças: diagnóstico e conduta a partir de relato de caso

“…Some authors observe that children vocal fold paralysis shows a slight predominance of unilateral paralysis 1,2 , whereas others observed higher frequency of bilateral paralysis 3,4 . However, when the lesion is unilateral, there is higher impairment of the left vocal fold [1][2][3][4][5] .…”

“…Some authors observe that children vocal fold paralysis shows a slight predominance of unilateral paralysis 1,2 , whereas others observed higher frequency of bilateral paralysis 3,4 . However, when the lesion is unilateral, there is higher impairment of the left vocal fold [1][2][3][4][5] . It may be explained by the fact that left recurrent laryngeal nerve presents a longer path 4 , and it may be related with ductus arteriosus 2 , making it susceptible to damage during the progression of many diseases and surgical procedures.…”

“…Vocal fold paralysis corresponds to 10% of laryngeal congenital anomalies 1 and it presents different etiology, clinical presentation and management when comparing children and adults. Some authors observe that children vocal fold paralysis shows a slight predominance of unilateral paralysis 1,2 , whereas others observed higher frequency of bilateral paralysis 3,4 .…”

“…The main signal of vocal fold paralysis in childhood, both unilateral and bilateral, is stridor, and laryngeal paralysis is the second most common cause of stridor in this age range 2 , second only to laryngomalacia. Bilateral paralysis is normally present with cyanosis and apnea 3,4 , whereas unilateral cases are presented with dysphonia and crying affections 1,4,7 . Considering bilateral paralysis, the main causes are neurological, idiopathic and birth trauma [1][2][3][4][5][6] .…”

“…Bilateral paralysis is normally present with cyanosis and apnea 3,4 , whereas unilateral cases are presented with dysphonia and crying affections 1,4,7 . Considering bilateral paralysis, the main causes are neurological, idiopathic and birth trauma [1][2][3][4][5][6] . Among neurological causes, Arnold-Chiari malformation, associated with meningomyocele and hydrocephalus, is the most common one and it is normally manifested at about the 3rd month of life [1][2][3][4] .…”
