Zusammenfassung:Vocal fold movement impairment (VFMI) is a well-known sequela of cervical and thoracic procedures performed in the vicinity of the recurrent laryngeal nerve. Interpretation of flexible nasolaryngoscopy (FNL) can be difficult in young children due to crying, secretions, and obstructing supraglottic structures. We have previously published on the use of radiologist performed and interpreted, laryngeal ultrasound (LUS) to evaluate vocal fold mobility with substantial agreement with FNL in infants in the cardiovascular intensive care unit. The purpose of this study was to evaluate point of care, clinician performed, LUS for vocal fold mobility in a pediatric voice clinic. LUS and FNL were performed and recorded on 30 consecutive patients (11 with a clinical diagnosis of VFMI and 19 with clinically normal mobility) in a pediatric voice clinic. All LUS was performed by a single clinician (reviewer 1) with a GE logiq P9 and 12 MHz linear probe. Deidentified recordings of the LUS and FNL (without sound) were reviewed in random order by 2 fellowship trained pediatric otolaryngologists who were blinded to the vocal fold mobility. Cohen's kappa was used to determine agreement. There was substantial agreement (κ  = 0.7) between the reviewers regarding interpretation of LUS as well as regarding interpretation of FNL κ  = 0.7802. In addition, each reviewer had near perfect to substantial agreement between their interpretation of the LUS and FNL (reviewer 1 κ  = 0.9294 and reviewer 2 κ  = 0.8413). Point of care, clinician performed, LUS can be used for the identification of VFMI with substantial agreement with FNL with good inter-rater reliability. This provides clinicians with another tool in their armamentarium for the evaluation of challenging larynges.
