Pulsitile Tinnitus
PULSITILE TINNITUS - Page 2
Pulsitile tinnitus can also be related to the following conditions:
From Otolaryngology Head and Neck Surgery, Eighth Edition, the chapter written by Dr. Alexander J.
Schleuning II (who practices at OHSU in Portland, Oregon). The
following notes are explanatory comments.
Pulsitile tinnitus related to: Vascular Abnormalities Arterioevenous shunts Congenital arteriovenous malformation Acquired arteriovenous shunts Glomus tumors of the jugular, Glomus tumors of the tympanicum
(middle ear area), Note: a glomus tumor is vascular non-cancerous growth in or near the blood vessels:
Pulsitile tinnitus related to: Arterial bruits (noises relating to the arteries-beating sounds) High-riding carotid
artery (close to the auditory areas), Carotid stenosis (closing or narrowing of the vessel),
Vascular loop (of the internal auditory canal), Persistent stapedial artery (close to the stapes bone).
Pulsitile Tinnitus related to: Venous hums (noises relating to slower blood flow) Dehiscent jugular bulb Hypertension (high blood pressure).
Pulsitile tinnitus related to: Mechanical Abnormalities Patulous eustachian tubes (open tubes leading from
throat to ear), Palatomyoclonus (small spasms of muscles in the soft palate area), Idiopathic stapedial muscle
spasm (the tiny muscle attached to the stapes bone in the middle ear space).
Pulsitile tinnitus can be heard as several characteristic sounds including a lower pitched thumping or
booming, as well as a rougher blowing sound which is coincidental with respiration, or as a clicking, higher
pitched rhythmic sensation. Finally, in some cases of pulsitile tinnitus there may be single, rhythmic beats, or
multiple biphasic beats (like the clip-clop of the horse), or a swishing, swooshing sound.
A rapid clicking sensation with pulsitile tinnitus may be due to the contractions of the middle ear and palatal
muscles. Low humming pulsitile tinnitus that is inaudible to the examiner may be due to venous blood flow or
associated with Meniere’s disease when accompanied by vertigo and fluctuating hearing loss.
Objective pulsitile tinnitus that is strongly associated with the timing of the heart beat is most likely the product
of a blood vessel - malformation of the arteries and veins of the head or neck area. These blood vessels are
located adjacent to the ear on the surface of the head or just inside the head. These pulsitile tinnitus cases
require special imaging techniques and often require surgery to resolve the pulsitile tinnitus.
It is our sincere hope that everyone who experiences pulsating tinnitus will pursue a thorough medical evaluation to locate the cause, if possible. There is a lot of research and reports about methods for repairing
the problems that create the disturbing symptoms of pulsitile tinnitus. At the same time, there are many cases
of pulsitile tinnitus which are not pinpointed, and these tend to fall into the idiopathic category (meaning
unknown causes). Individuals with pulsitile tinnitus who find that the initial imaging results do not reveal
abnormalities should insist on further examination and investigation. It is apparently possible to misread or miss these pulsitile tinnitus trouble spots that may be tangled in other structures or hidden by bone or other
tissue. Newer techniques regarding pulsitile tinnitus have been employed that help determine the site of
lesion in the majority of pulsitile tinnitus cases. The cure rates for pulsitile tinnitus are quite high, once the
problem area has been identified.
