[Bilateral vestibular loss. Diagnosis and follow-up].

Background: Atypical symptom in patients with bilateral vestibular loss is head movement-induced oscillopsia. The paucity of precise complaints in many patients is surprising. Therefore, bilateral loss of vestibular function is often undiagnosed.

[Pseudoemissions and false positive findings in measurement of transiently evoked otoacoustic emissions (TEOAE)].

Background: Recording procedure of transiently evoked otoacoustic emissions is an important part of diagnostics in pediatric audiology. As a rule of thumb measurable TEOAE excludes more than slight hearing impairment. Nevertheless any interpretation of these measurements in a clinical setting must consider supposed false positive findings (so called pseudoemissions) and real false positive findings in cases of profound hearing loss with reproducible TEOAE and missing auditory evoked potentials.

[Modified posterior Dennis and Kashima cordectomy in treatment of bilateral recurrent nerve paralysis].

Background: A number of different surgical methods are described in the literature to enlarge the glottic gap in patients with bilateral recurrent nerve paralysis with an excessively small glottic gap. The latest method is the posterior chordectomy described by Dennis and Kashima.

Patients And Methods: Twenty-three patients with bilateral recurrent nerve paralysis were treated between 1993 and 1997.

[Objective criteria for expert assessment of vestibular vertigo].

Background: Even for experienced examiners quantitative and objective medicolegal assessment of vestibular vertigo is difficult. Current medicolegal opinions place disproportionate emphasis of subjective symptoms.

Methods: Based on parameters from spontaneous and provoked vestibular nystagmus with Frenzel's glasses, objective criterias for adequate medicolegal assessment of vestibular disorders are presented.

[Paralysis of the superior laryngeal nerve after whiplash trauma].

Background: The current literature rejects the possibility of strain of the superior laryngeal nerves by whiplash injury. However, due to the anatomic situation and the mechanism of the whiplash injury this damage does not seem unlikely.

Patient: A 58-year-old male patient, who was a trained singer, complained of a loss of his head voice following a major whiplash injury.
