[A new cause of structural vertigo: superior semicircular canal dehiscence].

The medical history of vertigo must be updated to accommodate current knowledge. In 1998 a new cause of vertigo associated with a structural anomaly was reported: superior semicircular canal dehiscence. This condition causes vestibular and auditory disorders, which are frequently associated, and a well-directed medical history allows a suspected diagnosis to be reached: the subject may suffer from vertigo triggered by loud sounds (Tullio's phenomenon) and by changes in pressure within the ear or in the intracranial space, when Valsalva's manoeuvres are performed or on pressing on the tragus (Hennebert's sign).

Contribution to morphological knowledge of the development of the human incudo-mallear joint.

At the time of birth, the incudo-mallear joint is completely developed. OBJECTIVE. To study the development of the incudo-mallear joint in human embryos and fetuses.

[Ontogenic development of the incudostapedial joint].

Objective: To study the development of the incudostapedial joint in human embryos and foetuses.

Material And Method: 46 temporal bones with specimens between 9 mm and newborns were studied. The preparations were sliced serially and dyed using the Martins trichrome technique.
