めまい発症について気象因子に注目した遅発性内リンパ水腫の一例 A Case of Delayed Endolymphatic Hydrops in Which Vertigo was Influenced by Weather Factors
We experienced a case of Ménière's disease; the patient complained of attacks of hearing loss and vertigo that occurred depending on weather changes. However, a relationship between the disease and weather factors has not been previously reported. We report a case of delayed endolymphatic hydrops that was affected by the weather; we observed vestibular and cochlear symptoms during the clinical course. We recorded the relationship between weather factors (temperature, atmospheric pressure, and humidity) and vestibulocochlear symptoms in the patient for 2.5 years beginning from January, 2002. A significant relationship was observed between the atmospheric pressure data and the vestibulocochlear symptoms; this was greater than that for other factors such as temperature and humidity. The atmospheric pressure showed a high value when the patient experienced vestibular symptoms and a low value with cochlear symptoms. The vestibulocochlear symptoms were aggravated when the pressure changed by more than 10 hPa (increase or decrease) for several days. Based on the results of this study, a change in atmospheric pressure is considered to cause vestibulocochlear symptoms accompanied by an increase in endolymphatic hydrops. This change in endolymphatic hydrops is thought to be caused by a low atmospheric pressure in the middle ear and a corresponding high atmospheric pressure in the inner ear. It is difficult to accept that vertiginous disease is caused only by weather factors. The present case indicates a possibility for the prediction of vertiginous attacks by focusing on changes in atmospheric pressure.
