[Extratympanic electrocochleography in Ménière's disease].

Introduction: Electrocochleography is the registration of an electrophysiological event which takes place in the cochlea after an acoustical stimulus. Most of the authors consider an increased summating potential (SP)/action potential (AP) ratio as characteristic of endolymphatic hydrops.

Methods: A longitudinal, prospective study of a unilateral Ménière's population diagnosed according to the American Academy of Otolaryngology-Head and Neck Surgery classification was carried out.

[Eagle's syndrome: transient syncopes as a clinical manifestation; complete stylohyoid ligament calcification].

We report a case of a young man with transient syncopes as a first clinical manifestation. Neck radiographic examination showed a bilateral calcification of the stylohyoid ligament, doubly articulated in its extension and compressing the internal carotid artery.
