Abstract
Re-examination of flexible fiberoptic videotaped laryngeal images of 39 patients with unilateral recurrent laryngeal nerve paralysis (URLNP) by four observer-judges revealed consistent findings of a unilaterally appearing shorter vocal fold with asymmetry of the arytenoid complex on the involved side. No previous similar experience in otolaryngological training or practice has been encountered. Multiple discrepancies between and among observer-judges regarding vocal fold positions during phonation were encountered. Possible explanations are discussed. The need for further investigation to determine the mechanics causing these differences is stressed. It is suggested that for the present, such terms as median, paramedian, and intermediate be used in teaching and in practice as generalities only.
