A treatise on the diseases of the ear including the anatomy and physiology of the organ together with the treatment of the affections of the nose and pharynx which conduce to aural disease . other hand, in some cases, owing to peculiarformation of the naso-pharyx. phonation proves to be the moresuccessful plan. In the case of children, Hinton used frequently to inflate the no EXAMIXATIOX OF THE NOSE. ETC. tympana by blowing through a piece of india-rubber tubing, oneend of which was inserted in his mouth and the other in one ofthe childs nostrils. The instrument which I usualh employ for Politzers inflation(Fig. 41) has a capacity of ten ounces, and is fitted with either anindia-rubber teat or Allens pads. (Fig. 45.) The length of thetubing between the bag and its nozzle—about sixteen inches—-enables the surgeon to move his arm freely whilst compressingthe bag, and prevents the possibility of injury being caused by anymovement of the surgeons hand being communicated to thepatients nose. When Politzers method of inflation is used, thepatient should always be seated, because giddiness is liable to be pro-duced by the sudden increase of pressure of air in the tympanum. 1. Fig. ).Dr. Pkikr Allexs Aik-Pads. Results of Passage of Air into Tympanum: Use of Manometer. —The passage of air into the tympanum generally gives riseto a decided sensation of fulness or pressure. The membranatympani is bulged outwards, the change in this respect beingmore decided than that which results from Valsalvas movement of the membrane can be positively tested bythe insertion of an ear-manometer into the external little instrument consists of a small glass tube, one portionof which is straight and the other (J^^^^P*^*^^- The latter containsa drop or two of coloured fluid, and the straight piece is fittedinto an india-rubber stopper, adapted to the size of the this manometer is inserted hermetically within the canal,and Politzers method practised, th
