Extra-tympanic electrocochleography in a normal population. A descriptive study.
2015
Abstract Introduction and objectives Extra-tympanic electrocochleography is an electrophysiological register obtained after stimulating the cochlea with an audible stimulus. This stimulus is applied using an earphone over the external auditory canal, while the electrical activity is registered by surface electrodes. There are few studies that analyse normal electrocochleography in our environment. Thus, the main objective of our study was to regularise the values obtained with electrocochleography in ears without any otoneurological diseases. We explain in detail the process of obtaining the register. Methods Sixty healthy ears were studied by extratympanic electrocochleography. Statistical…
Comparison of Electrocochleography and Video Head Impulse Test findings in Vestibular Migraine and Ménière Disease: A Preliminary Study
2020
OBJECTIVES: To evaluate electrophysiological findings among patients with vestibular migraine (VM) and to compare them with those of patients suffering from definite Ménière disease (MD) without migraine. MATERIALS and METHODS: Twenty-one consecutive patients suffering from VM were enrolled; all subjects were selected according to the criteria proposed by the Bàràny Society for Neuro-otology. Each patient underwent a careful otological and neurotological examination. After completing a questionnaire regarding migraine and vertigo complaints, they were assessed by audiometric testing, video head impulse test (vHIT), and elec-trocochleography (EcochG). Data were compared with those of 21 pati…
Diagnostic Role of Combined Electrocochleography and Pure-Tone Audiometry Monitoring During Dehydrating Test in Ménière's Disease: A Case Series
2023
Objectives: To evaluate the diagnostic role of combined electrocochleography and pure-tone audiometry monitoring during dehydrating test in Ménière's disease and consider its suitability as a diagnostic tool to differentiate those patients with unclear differential diagnosis and therefore identify those with clear endolymphatic hydrops responsive to dehydrating test. To study the efficacy of dehydrating therapy on vertiginous symptoms and hearing loss in patients with Ménière's disease. Study design: Prospective case series. Settings: University hospital, secondary referral center. Patients: Thirty patients, 20 women and 10 men, age range of 25 to 75 years, matching the criteria for definit…
