Test-retest reliability of p13n23 and n34p44 components of vestibular evoked myogenic potentials in a large healthy population.

Objective: The aim of this study is to evaluate the reliability of the VEMP characteristics recorded in a large number of healthy subjects.

Methods: VEMP response was obtained on 75 healthy volunteers. Thirty-nine (39) of them were males and 36 were females.

Vestibular evoked myogenic potential eliciting in normal subjects: comparison of four different methods.

Objective: Vestibular evoked myogenic potential (VEMP) recording is a new method for testing the otolith receptors and vestibulospinal pathways. The aim of this study was to evaluate the characteristics of VEMP using four different techniques to find reasons to prefer one type of recording over the others.

Material And Methods: Twenty healthy persons, 10 males and 10 females with ages ranging from 20 to 57 years (mean age 41 years), were enrolled in this study.

Metallic foreign body in middle ear: an unusual cause of hearing loss.

This is a rare case report of a foreign metallic body found in the middle ear. During the use of an electric welding by a metalworker, a glowing drop of dissolved metal overrun, burning the skin of his external auditory meatus, perforated the tympanic membrane and finally was implanted around the ossicles as a foreign body. Due to difficulty of the physical examination and the moderate symptoms (hearing loss and sense of fullness), the foreign body was detected six months after the incident, by CT scanning and it was removed by a transcanal approach under general anesthesia.
