Dysyncea Laryngea. Roaring. Hemiplegia Laryngea. i6i 



The other operations of : — excision of the left vocal cord and 

 ablation of the ventricle (Gunther) ; — the fixation of the aryte- 

 noid to the thyroid (Gunther) ; — the excision of the left vocal 

 cord and suture of the crico-arytenoid membrane to the thyroid 

 (Merilat) ; — the suture of the crico-arytenoid membrane by in- 

 corrodable gold wire to the thyroid (Williams) ; — and the suture 

 of the left recurrent laryngeal nerve to the parent trunk of the 

 vagus near the larynx ; have each proved but partially and as a 

 rule temporarily beneficial. 



Another obvious line of treatment is by the use of electricity 

 locally and of strychnine internally. A weak current kept up for 

 fifteen minutes may be sent from the positive pole in the left jug- 

 ular furrow to the negative pole over the left side of the larynx. 

 Strychnia in the dose of two' grains may be given daily in the 

 food or in half that amount hypodermically over the left side of 

 the larynx. This would be useful only in the early stages with 

 little or no fatty degeneration of the muscles. It is the recent, 

 slight cases that are benefited in this way, and some such have 

 even recovered under light firing over the region of the larynx.
