[Laryngeal and hypopharyngeal carcinoma--the limits and advantages of sonography].

29 patients with carcinoma of the larynx and the hypopharynx were evaluated not only for staging cervical lymph nodes but also for classification of the primary tumour. With appropriate technique it is possible to assess tumour infiltration (T4) of surrounding tissue of the larynx at all levels. Tumour classification T1 to T3 is possible in patients with tumour of the epiglottis (regio supraglottis, UICC).

[Experiences with a non-inflammable tube in laser surgery of the larynx].

With the recently developed noncombustible copper-tube dangerous damages caused by tube-ignition in the larynx will certainly be avoided.

[Sudden deafness in old age].

The sudden hearing impairment sensu stricture constitutes an otologic emergency, the genesis of which is still a mystery. The one-sided, reduced auditory sensitivity (labyrinthine deafness, sensorineural lesion) occurs unexpectedly and, more often than not, in good general condition with the remaining otologic diagnosis showing almost no anomalies. The cause for this impairment is considered to be a cochlear malfunctioning of the microcirculation with ensuing hypoxia/anoxia in stria vascularis and in Corti's organ, which is caused by a change in the circulation qualities of the blood (hemagglutination, aggregation of thrombocytes etc.

[A meaningful antibiotic therapy of diseases of the ear, nose and throat in old age (author's transl)].

Each stage of life is characterized by the prevalence of certain affections; among others, inflammatory diseases of the ear, nose and throat are frequent in old age. Therefore, specific problems of chemotherapy in old age are dealt with in general terms in the introduction, with special stress being placed on the functions of individual organs, mainly of the kidneys, and on questions of disturbed absorption. Inflammations caused by streptococci, requiring at least ten days of antibiotic treatment, always deserve particular attention, and so do staphyloccocal diseases, requiring the selective administration of semi-synthetic pencillines (sioxazol preparations).
