Electrical stimulation of the posterior cricoarytenoid muscle, synchronized with inspiration, was achieved in dogs utilizing a radio frequency stimulus triggered by a chest wall expansion transducer. This system brings about abduction of the paralyzed vocal cord for the entire duration of inspiration, which allows a normal flow of air through the larynx.(More)
Patients with bilateral paresis of the recurrent laryngeal nerves have primarily breathing difficulties. But on the other hand the common operations for widening the glottis produce voice problems. To overcome these difficulties a muscle stimulation device was developed, which is triggered by the inspiratory motion of the thorax. With this device impulses(More)
The decreas in microphonic potentials detected from the round window (RMP) is negligible only if the bores are located very close to the round window, whereas it will increase with increasing distance from it. Only at pressures of more than +/- 30 cm water column, in rare cases even below that, will a sharp decrease in the RMP occur, possibly because of a(More)

The temporal bone collection of the ENT Department of the Charité Hospital in Berlin contains 128 cases from 1924 to 1941 of fatal complications of acute otitis media and cholesteatoma. In 1927 alone, one patient died on average every 2 weeks at Charité Hospital from fatal otitic disease. Lesions include labyrinthitis, meningitis, sinus thrombosis and brain(More)
