Considerable diminution or total loss of hearing. It may be the effect of acute or chronic inflammation of the internal ear, paralysis of the auditory nerve or its pulpy extremity, or of some mechanical obstruction to the sonorous rays. In most cases, however, the cause of the deafness is not appreciable, and the treatment has to be purely empirical. Syringing the ears, dropping in slightly stimulating oils, fumigations, &c., are the most likely means to afford relief.
