Abstract
Our aim was to present laryngovideostroboscopic findings in unilateral superior laryngeal nerve paresis and paralysis. Retrospective case review, academic voice clinic. Blinded retrospective review of videostroboscopic recordings from cases confirmed by laryngeal electromyography. Three cases of unilateral superior laryngeal nerve paresis and paralysis were identified. At rest, there were no common abnormal laryngeal findings. Upon phonation, common findings were ipsilateral vocal fold bowing and shortening, vocal process height asymmetry with the ipsilateral vocal process overriding the normal, and ipsilateral hyperadduction of the false vocal fold. The common features noted in these cases of laryngeal electromyography-proved uSLNp could be used to make a presumptive diagnosis of this disorder.
