Idiopathic endolymphatic hydrops is a histopathological hallmark of Menière’s disease and other volume regulation-related inner ear disorders. It manifests as a triad of symptoms: episodic vertigo, tinnitus and hearing loss. In this study we used electrocochleography in order to diagnose Menière’s disease. Electrocochleography is a method of recording the stimulus-related potentials of the cochlea and the auditory nerve. In one of the three presented cases, analysis of the electrocochleographic waveform shows endolymphatic hydrops. In diagnosing Menière’s disease, electrocochleography is a fairly consistent indicator of the presence of endolymphatic hydrops, in addition to the anamnesis and examination of patients.

Идиопатичният ендолимфатичен хидропс е хистопатологичният белег на Мениеровата болест и на други нарушения на обемната регулация на течностите във вътрешното ухо. Клинично се проявява с триада от симптоми, включваща епизодично вертиго, тинитус и намаление на слуха. В настоящото проучване използвахме електрокохлеография за доказване на Мениеровата болест. Това е електрофизиологичен метод, регистриращ потенциали от кохлеата и слуховия нерв в отговор на звукови стимули. Анализът на електрокохлеографската крива показва хидропс на лабиринта в един от представените три случая. Електрокохлеографията е сравнително постоянен индикатор за наличието на ендолимфатичен хидропс и допълва данните от анамнезата и физикалния преглед при доказването на Мениеровата болест.
