It is a rare disease that appears in less than 12 hours with a sharp reduction in hearing in three adjacent audiometric frequencies.
Usually, the aetiology cannot be ascertained, although it has been attributed to a viral infection, vascular disorders (thrombosis or embolisms), autoimmune diseases and traumatisms. The most common case is for it to affect only one ear.
Regarding the symptomatology, in addition to deafness, the feeling of a plugged ear and ringing (tinnitus) may also occur.
Diagnosis is reached through the clinical history and a complete physical examination. The audiometric examination will help to classify the type of deafness.
Treatment will vary depending on the triggering cause: vasodilator medication, corticosteroids, antiplatelet medication, antivirals, etc.
