Abstract
Tinnitus is a relatively frequent symptom in an otolaryngology consultation. Interactions in external or internal hair cells, imbalances in the afferent fiber balance and cortical reorga- nization phenomena after peripheral injuries have been described in 90%-95% of the causes of tinnitus. The remaining 5%-10% is comprised of a type of tinnitus called objective, which do not share these pathophysiological mechanisms, but originate from some structure of the body generally external to the auditory pathway and stimulate the auditory apparatus just as a sound from the exterior. We present the case of a 52-year-old man referred to the Otolaryngology service at our hospital for pulsatile tinnitus of months of evolution, with no hearing loss, vertigo, or other symptoms associated.
