Paralysis of all the muscles supplied by one recurrent oftengives very meagre subjective symptoms. The voice may be onlyweak and uncertain; sometimes, however, it is lost. The laryn-goscopy appearances are characteristic ; the band on the affectedside remains immobile in the mid, or cadaveric, position, asfound after death. During inspiration the unaffected band iswidely abducted; and, although, on attempted phonation, it mayonly reach the median line, as a rule, it passes beyond it in theeffort to assist the vocal function, by assuming a share of the 358 DISEASES OF THE NOSE AND THROAT. work of its disabled companion.
