[Acute pseudoperipheric vertigo and Wallenberg syndrome].

We report an atypical Wallenberg syndrome presented with an acute vertigo, preceded by headache, simulating a peripheral vestibular pathology. The first Magnetic Resonance Imaging (MRI) study done in urgencies is negative. Presence of headache, strong lateral ataxia and secondary focally neurological symptoms 48h after the beginning of the crises, lead to a repetition of the MRI which shows a right lateral bulbar infarct.

Négrevergne otoplasty technique.

Objectives: More than 200 different otoplasty procedures have been described in the literature to treat patients with prominent ears. However, no simple "best" technique exists.

Methods: The Négrevergne otoplasty technique was developed by Michel Négrevergne and adopted in the Georges Portmann Institute in France.

[Dehiscence of the superior semicircular canal: approach and CT scan classifications].

Unlabelled: The syndrome of dehiscence of the superior semicircular canal (DCSS) is primarily associated with vertigo and/or hearing loss. The dehiscence may be completely asymptomatic and represent an incidental finding on radiological investigation.

Objectives: To demonstrate the advantages of a volume rendered CT study of the petrous temporal bone of patients with hearing loss, and to demonstrate the effectiveness of its systematic application in the protocols of examination.

[Skull vibration induced nystagmus test].

Objectives: To establish during a consensus meeting the fundamental basis, the validity criteria, the main indications and results of the skull vibration induced nystagmus test (SVINT) which explores the vestibule high frequencies.

Material And Methods: The SVINT is applied on the mastoid process (right and left sides) at 100 Hz during 10 seconds on a sitting upright subject. Total unilateral peripheral lesions (tUVL: operated vestibular shwannomas, vestibular neurectomies) and partial unilateral peripheral lesions (pUVL: preoperative neuromas, Meniere's disease, vestibular neuritis, chemical labyrinthectomies) were studied.

Bilateral cochlear implantation in a patient with long-term deafness.

Purpose Of The Study: 1) To report the case of a 70-year-old patient with a history of auditory deprivation for 80% of his life and who received bilateral cochlear implants and 2) to discuss different aspects of the case, including duration of auditory deprivation, the decision for bilateral implantation, age at implantation, and the use of this treatment modality for tinnitus.

Case Report: A two-stages bilateral cochlear implantation was performed in a 70-year-old patient with long-term deafness without operative or post-operative problems with excellent functional result.

Discussion: Various studies have reported that in patients with long-term auditory deprivation, the results of cochlear implants are delayed and sometimes unsatisfactory when compared to patients with more recent post-lingual deafness.
