Internal Jugular Vein Compression Collar for Novel Symptomatic Treatment of Venous Pulsatile Tinnitus
Internal Jugular Vein Compression Collar for Novel Symptomatic Treatment of Venous Pulsatile Tinnitus
This study seeks to pilot an evaluation of whether an external jugular vein compression collar approved by the US Food and Drug Administration (FDA) for contact sports can provide symptomatic relief of venous pulsatile tinnitus. Furthermore, the study will evaluate quality of life impacts of the device and adherence by users.
Background: Tinnitus is a medical condition with a wide variety of causes that is characterized by the perception of sound, often described as ringing or buzzing, without an external stimulus. Venous pulsatile tinnitus is a specific subtype of tinnitus with limited treatment options: some cases can be treated with surgical correction of an underlying vascular defect, others are entirely idiopathic. The clinical diagnostic hallmark of venous pulsatile tinnitus is relief of symptoms with light compression of the ipsilateral external jugular vein by the physician. Internal jugular vein compression collars, FDA approved devices currently used to prevent brain injuries in contact sports, function by this exact same method. Therefore, it is believed that these collars can treat pulsatile tinnitus.
Study Design:
This is a non-blinded, interventional, prospective single cohort pilot study that will recruit 20 patients diagnosed with pulsatile tinnitus at the UNC Meadowmont Ear Nose and Throat (ENT) clinic (see methods for inclusion/exclusion criteria). Volunteers will compare tinnitus intensity before and after administration of the collar, take the collar home and evaluate its symptomatic efficacy over a 2-4-week period, and return to clinic to complete data on quality of life and longitudinal impacts. This data will be analyzed for significance.
Expected Outcomes:
It is expected that collar administration will offer immediate symptomatic relief, illustrated as significant improvement on the tinnitus intensity scale during their initial clinic visit Symptomatic improvement will be sustained while wearing the collar, measured by sustained improvement in the tinnitus handicap inventory over the course of the study. Lastly, the collar will improve quality of life as measured by patient reported outcome scales administered pre and post participation.
