A manual of diseases of the throat and nose : including the pharynx, larynx, trachea, oesophagus, nose and naso-pharynx . ortion of the right pneumogastricnerve (which, of course, includes the nerve-fibrils ultimately forming thesuperior laryngeal nerve), the muscles of the epiglottis acted normally,and the sensibility of the larynx remained intact, though there was com-plete paralysis of the right vocal cord, is probably to be explained by thecompensatory action of the left nerve. There is, however, much difficultyin meeting the cases of That excellent observer has reportedseveral cases of pure paralysis of the recurrent nerve in which there wasatrophy and fatty degeneration of the crico-thyroid muscle, as well as ofthe laryngeal muscles supplied by the recurrent, whilst the superior laryn-geal nerve appeared quite normal under the microscope. 1 Riegel: Volkmanns Samml.

Prognosis^—In complete paralysis of both superior laryngeal nervesithe patients condition is attended with considerable danger, but if onlyone nerve is affected there seems to be little risk. In the former case thepatient may either perish from inanition through refusing to take food,or from pneumonia if he continues to swallow aliment in the natural man-ner. Cases have been reported by Weber,1 Maingault, ? Monckton,3Ziemssen,4 and others, in which a fatal termination of paralysis of thethroat could only be accounted for by lobular pneumonia, brought aboutno doubt by the passage of food down the air-tracts. Diagnosis.—The recognition of this form of laryngeal neurosis canonly be accomplished with the laryngeal mirror and probe, and has alreadybeen referred to in dealing with anesthesia of the larynx (page 305
