Vestibular status in partial deafness.

Introduction: The hair cells of the cochlea and the vestibulum are closely connected and may be susceptible to the same noxious factors. The relationship between their function has been a continuing field of investigation. The indications for cochlear implantation have been broadened and now include the patients with partial deafness.

Effect on vestibular function of cochlear implantation by partial deafness treatment-electro acoustic stimulation (PDT-EAS).

Purpose: Although the cochlear implantation procedure does not interfere with vestibular structures directly, both the vestibulum and the cochlea share the same inner ear fluid space, and this fluid may be responsible for transferring possibly damaging forces from one to the other. The purpose of the study is to assess postoperative vestibular function after partial deafness treatment-electro-acoustic stimulation (PDT-EAS) cochlear implantation.

Methods: Fifty-five patients were included in the study (30 females, 25 males, age 11-80, mean 41.

Assessing Gait Stability before and after Cochlear Implantation.

Background: It is known that cochlear implantation may alter the inner ear and induce vestibular disorders.

Research Question: How does cochlear implantation influence gait stability? . An experimental group of twenty-one subjects scheduled for cochlear implantation underwent gait testing twice, on the day before cochlear implantation (BCI) and three months after cochlear implantation (ACI), using a motion capture system.

[Tornwald's cyst in clinical practice].

Aim: Tornwald's cyst is a recess in the midline of the nasopharynx, which is produced by persistent notochord remnants. The aim of the study was to present difficulties in diagnostic procedures in patients with Tornwald's cyst suspicion.

Material And Method: Authors present 2 cases of patients being treated for Tornwald's cyst in the Audiology and Phoniatrics Clinic of Institute of Physiology and Pathology of Hearing in Warsaw.
