Evaluation and Treatment of Pulse-Synchronous Tinnitus (.1 CEUs)
Duration: 1 hour
Presenter: David J. Eisenman
Who Should Attend: Any audiologist who is interested in tinnitus
Program Focus: Knowledge
Upon completion, each participant in the eAudiology Web seminar will be able to::
1. Describe 2 different pathophysiologies of pulse-synchronous tinnitus (PST)
2. Name 3 most common causes of PST
3. Explain audiometric findings in superior semicircular canal dehiscence
4. Explain the relationship between intracranial hypertension and PST.
Tinnitus is the abnormal perception of sound in the absence of an external sound source. Objective tinnitus can be defined as an abnormal perception arising from an internal somatosound; an actual mechanical sound source, though one that should not usually be perceived. The most common form of objective tinnitus is pulse-synchronous tinnitus (PST), caused by abnormal perception of one's own vascular flow. Unlike the more common, idiopathic, non-rhythmic tinnitus, most PST has an identifiable- and often treatable- cause. PST can be due to abnormal sound perception or abnormal sound production. In this eAudiology Web seminar, we will understand the pathophysiology underlying the most common forms of PST, and learn how to distinguish them based on a history, physical exam and audiometric testing. We will review two common causes that are paradigmatic of each of the broad pathophysiologic categories, and discuss treatment approaches.
