![When otorrhoea is accompanied by caries or necrosis of the temporal bone, we can never consider a patient to be out of danger, as it is impossible to tell whether the disease will extend to the many vital parts which surround the ear. In this way the brain and its mem- branes, the petrosal and lateral sinuses of the dura mater, the jugular vein, and internal carotid artery, are all exposed to injury, and a fatal termination may depend upon extension of in- flammation to any one of them. Sudden cessation of discharge from the ear often precedes symptoms of a serious nature, and for this reason many persons, both doctors- and patients, are afraid to cure otorrhoea. This fear is only well founded when the cessation is brought about by such means as tend to keep back the discharge, which thus becomes a source of irritation to the important structures around. In addition to diseases of the middle ear, which have hitherto occupied our attention, defective hearing may depend upon obstruction, from various causes, situated in the meatus externus. These affections are not nearly so common as those which have been mentioned and are sufficiently evident on examination to render any description unnecessary. ]) 2](https://iiif.wellcomecollection.org/image/b21446684_0041.jp2/full/800%2C/0/default.jpg)
