Clinical presentation of paradoxical vocal fold motion or laryngeal dyskinesia in infants

We present the largest case series of PVFM in infants. We found sparse clinical signs/symptoms other than stridor and a high incidence of misdiagnosis, which supports the importance of objective flexible laryngoscopy for the evaluation of stridor in this age group. Previously reported sex- and race/ethnicity-based differences in presentation of PVFM were not observed in this cohort of infants.
