[Pulsatile tinnitus. Causes, diagnostic procedures, case presentation].

The pulsatile tinnitus is a rare sign. It is characterised by a rhythmic sound that is synchronous with the patient's heart beat. The underlying causes vary widely and may be life-threatening.

[Internal occlusive hydrocephalus following cholesteatoma].

A 30-year-old Vietnamese patient is reported who was admitted with a resistant acute otitis externa, and who complained also of headache and fever. The symptoms were found to be caused by the intracranial complications (epidural abscess and bacterial meningitis) of an aural cholesteatoma. A secondary occlusive hydrocephalus developed in spite of successful otological surgery that preserved hearing and vestibular function.

[Roentgen cinematographic studies in patients who snore].

A radiocinematographic procedure of the pharyngeal examination of snorers is presented. By swallowing, by the production of pharyngeal sounds and by the forced inspiration which produces snoring sounds a dysfunction or an obstruction in the upper respiration tract can be located. This method is a useful diagnostic aid in snoring disease which should precede surgical interventions in the pharynx.
