Seite 283 - The peculiar poison which causes the disease generally known by the name of mumps is very often the source of complete deafness, which, however, usually occurs in one ear only. In these cases, the nervous apparatus is evidently affected, as the deafness comes on suddenly, is usually complete, and, as a general rule, no appearance of disease can be detected in the meatus, membrana tympani, or tympanic cavity.
Seite 7 - The anterior of these sections should pass in a line a little anterior to the anterior clinoid processes, and the posterior in a line through the posterior third of each mastoid process. By means of these two sections the trumpet-shaped extremity of each Eustachian tube, a portion of the mucous membrane of the fauces, and the whole of each petrous bone, together with the mastoid process, can be taken out.
Seite 9 - The cavities of the vestibule and cochlea, are to be exposed by removing a small portion of the upper wall of each. Before reaching the vestibule, the superior semicircular canal will be cut through and removed; the membranous canal should be drawn out and inspected. As the cavities of the vestibule and cochlea are laid bare, it is desirable to see that the quantity of perilymph is natural, as well as its colour and consistence. The outer surface of the membranous labyrinth having been observed,...

It is also indispensable to success that the moisture of the wool should be preserved...
Seite 7 - ... inwards than the basilar process of the occipital bone. These two sections are to be made with a saw, or with a chisel and hammer ; the apex of each petrous bone is then to be separated from the sphenoid and occipital bones, and each petrous bone, the outer ear and integument being detached and reflected downwards, is to be drawn outwards, taking care, by inserting the scalpel deeply, to remove as much of the soft parts as possible. With this second plan there is a difficulty in removing the...
Seite 161 - ... wall was removed, it was with difficulty that an ordinary-sized bristle could be introduced into the opening. This stricture resulted from the external and internal walls of the tube pressing against each other, the small space, still permeable, being at the upper part.
Seite 7 - Eustachian tube; with care, however, this portion may be removed, especially if the final sections separating the petrous bone from the occipital and sphenoid be made to pass obliquely from above downwards and inwards. The organ of hearing having been removed, the dissection may be conducted in the following manner : The auditory nerve in its meatus should be first carefully examined, premising that a previous inspection has been made of the portion of the brain to which the portio mollis and portio...
Seite 311 - ... filled and emptied of air ? Though suggestions to this effect occur in some of our best works on Consumption, as well as in the writings of certain continental physicians, they have hitherto had less than their due influence, and the principle as such is little recognized or brought into general application.
Seite 311 - ... or brought into general application. In truth, common usage takes for the most part a directly opposite course ; and, under the notion or pretext of quiet, seeks to repress all direct exercise of this important function in those who are presumed to have...
Seite 8 - ... the portion of the brain to which the portio mollis and portio dura nerves are attached. The size of the external meatus having been ascertained by allowing a strong light to fall into it, its anterior wall is to be removed by the cutting forceps. The state of the epidermis, the eeruminous glands and secretion, the dermis, periosteum and bone, are to be noticed.
