The neuritis following diph-theria or typhoid fever may also result in paralysis of the inferiorlaryngeal nerve. In this condition the cord affected assumes thecadaveric position midway between abduction and adduction, the apexof the arytenoid being tilted forward. The unaffected cord crossesthe middle line in phonation to meet the opposite cord, the soundarytenoid passing in front of the paralyzed arytenoid, giving a verydistorted laryngeal picture. The loss of voice is usually not very. Fig. 139. Partial Paralysis of Right Recurrent during Respiration. marked, complete aphonia being the rule only when both recurrentnerves are affected. Paralysis of one nerve usually develops slowlyand, as it progresses, the opposite cord has time to compensate for theloss of action on the part of the paretic vocal band (Fig. 139). The prognosis of recurrent laryngeal paralysis depends upon thelocation of the disease and upon its duration. \Yhen it has existed -€?- Fig. 140. Partial Paralysis of Right Recurrent during Phonation. for many months degenerative changes may have occurred in themuscles which cannot be overcome (Fig. 140). The treatment should be governed by the nature of the cause ofthe affection. Post-diphtheritic cases recover under tonic doses ofstrychnia and the use of electricity. These methods, of course,should not be used in cases of paralysis due to aneurism or to pres- PARALYSIS OF THE LARYNX. 4O3 sure upon the trunk of the nerve
