Question
Is there any way to determine the etiology of occasional tinnitus, i.e. - tinnitus that occurs spontaneously, only lasts a short time, comes and goes and shows no pattern?
Even if the patient has hearing loss, is occasional tinnitus just a normal occurrence that normal hearing people experience or must it be connected to the hearing loss, noise exposure, medication, etc?
Answer
Rapidly appearing intense but short lived tinnitus is often associated with small muscle spasms located in the middle ear space. These very tiny muscles contract and tighten the eardrum area, causing a characteristic and noticeable 'loss of hearing' just prior to the onset of fairly loud high pitched tinnitus, which gradually fades over a few seconds or at most a minute or two. These little episodes are very common and are associated with jaw or neck tension, caffeine, or sometimes head position, although they certainly can show up spontaneously without obvious cause.
Sometimes people with tinnitus worry that these short term episodes may be signs of further damage or deterioration of the auditory system, but they are actually harmless little benign events similar to a temporary twitch in a toe or finger muscle. Almost everyone experiences these transient tinnitus events and there is no clinical evidence that connects them with other more serious cases of tinnitus or hearing loss.
