Tinnitus prevalence in New Zealand.

CONCLUSION: This is the first nationally representative study of tinnitus prevalence in New Zealand and largest study sample internationally for tinnitus prevalence to date. Tinnitus is a public health problem affecting approximately 207,000 people in the New Zealand population aged ≥14 years. This study has highlighted the importance of sex and age in defining a high-risk tinnitus population, but our knowledge falls short of profiling their ethnic and social-economic characteristics.

Arterial Abnormalities Leading to Tinnitus

Publication date: Available online 28 February 2016 Source:Neuroimaging Clinics of North America Author(s): Timothy R. Miller, Yafell Serulle, Dheeraj GandhiTeaser Tinnitus is a common symptom that usually originates in the middle ear. Vascular causes of pulsatile tinnitus are categorized by the location of the source of the noise within the cerebral-cervical vasculature: arterial, arteriovenous, and venous. Arterial stenosis secondary to atherosclerotic disease or dissection, arterial anatomic variants at the skull base, and vascular skull base tumors are some of the more common causes of arterial and arteriovenous pulsatile tinnitus. Noninvasive imaging is indicated to evaluate for possible causes of pulsatile tinnitus, and should be followed by catheter angiography if there is a st…

Clinical Evaluation of Tinnitus

Publication date: Available online 28 February 2016 Source:Neuroimaging Clinics of North America Author(s): Ronna Hertzano, Taylor B. Teplitzky, David J. EisenmanTeaser The clinical evaluation of patients with tinnitus differs based on whether the tinnitus is subjective or objective. Subjective tinnitus is usually associated with a hearing loss, and therefore, the clinical evaluation is focused on an otologic and audiologic evaluation with adjunct imaging/tests as necessary. Objective tinnitus is divided into perception of an abnormal somatosound or abnormal perception of a normal somatosound. The distinction between these categories is usually possible based on a history, physical examination, and audiogram, leading to directed imaging to identify the underlying abnormality. (Source:…
