To be able to monitor recovery of vocal\u2010fold motion in studies with rats, we developed a procedure for quantitative video laryngoscopy. An asymmetry index was defined as a continuous and robust measure of unequal vocal\u2010fold motion and calculated from spectral\u2010density plots of vocal\u2010fold displacements. In a cohort of 8 animals, unilateral vocal\u2010fold paralysis was observed within seconds after clamping of the right recurrent laryngeal nerve and was accompanied by a markedly negative asymmetry index. Over the next month, the asymmetry index gradually returned to zero, concomitant with a visible recovery of vocal\u2010fold motion. Our results suggest that quantitative video laryngoscopy is a sensitive and discriminating method for monitoring recovery from recurrent laryngeal nerve injury and set the stage for testing novel surgical and pharmacological treatments of unilateral vocal\u2010fold paralysis.<\/jats:p>","DOI":"10.1177\/0194599814521572","type":"journal-article","created":{"date-parts":[[2014,2,1]],"date-time":"2014-02-01T00:59:15Z","timestamp":1391216355000},"page":"824-826","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Quantitative
