Deep vein thrombosis in ear, nose and throat surgery.

I. One hundred and three patients undergoing head and neck or ear operations were screened for deep vein thrombosis using I125 labelled fibrinogen. 2. No thrombosis was detected in thirty-five patients undergoing ear operations. 3. Nine (16%) of fifty-six patients who underwent head and neck operations subsequently developed deep vein thrombosis. In a further twelve patients undergoing head and neck operations the ankle was used as a drip site and seven of these patients developed thrombosis in that leg.

Extra-tympanic electrocochleography.

A non-invasive technique for recording the cochlear action potential in adults without recourse to sedation or local anaesthesia is presented. This technique has been assessed in two ways: (1) A group of normal subjects was tested to obtain distributions of response amplitude and latency as functions of stimulus intensity. (2) A group of patients with Meniere's disease was tested with trans- and extra-tympanic electrocochleography to compare the intensity amplitude functions and wave-forms obtained from the two methods. On the basis of this study the use of extra-tympanic electrocochleography as a replacement for the trans-tympanic method is discussed.
