Causes of Tinnitus: Cerebrovascular Diseases

One-year prevalence and risk factors of tinnitus in children with otological problems

“…The earlier literatures also reported that children with tinnitus had the experience of headache and giddiness. The reason could be that both tinnitus and headache have common pathophysiology which suggests that each one of these symptoms could amplify each other and one of these symptoms might cause the other 33 .…”

Tinnitus - selected models of phantom sound perception

“…wystrzał z broni palnej), a także nadużycia aspiryny (Jastreboff, Hazell, 2004). Zjawisko to jest jednym z trzech głównych objawów choroby Meniere'a (obok zawrotów głowy i niedosłuchu, Ying, Arriaga, 2011) i może być następstwem zapalenia nerwu przedsionkowo-ślimakowego (May, Ramachandran, Cacace, 2011), nerwiaka nerwu słuchowego (Raj-Koziak i in., 2003), choroby naczyniowo--mózgowej (Láinez, Ponz, Piera, 2011). Szumy uszne somatosensoryczne mogą mieć także związek z problemami z szyją i/lub głową (Sanchez, Rocha, 2011).…”

Incidence of Vascular Anomalies and Variants Associated with Unilateral Venous Pulsatile Tinnitus in 242 Patients Based on Dual-phase Contrast-enhanced Computed Tomography

“…The vascular anomalies and variants on symptomatic and asymptomatic sides were analyzed and evaluated retrospectively. These evaluated vascular anomalies and variants were diagnosed on the following previously described criteria [ Figure 1 ]: (1) High jugular bulb, the jugular bulb extended above the inferior border of the round window;[ 1 ] (2) dehiscent jugular bulb or dehiscent sigmoid plate, the incomplete thin bone around the jugular bulb or the sigmoid sinus;[ 4 10 ] (3) jugular bulb diverticulum, prominent protrusion or an irregular out-pouching of jugular bulb that was clearly distinguished from a smooth ellipsoidal form;[ 22 ] (4) sigmoid sinus diverticulum, a diverticulum entered into the mastoid bone;[ 9 ] (5) lateral sinus stenosis, the L/S ratio (L = the largest area of the vein; S = the smallest area of the vein) was >4.75;[ 11 ] (6) large emissary vein, diameter of the emissary veins was >3.5 mm;[ 12 ] (7) petrosquamosal sinus, embryologic emissary vein running along the petrosquamosal Fissure;[ 15 ] and (8) sinus thrombosis, signs of thrombosis were noted, including the empty δ-sign or an irregular filling defect. [ 23 ] These anomalies and variants were analyzed in each patient and summed.…”

“…Vascular pulsatile tinnitus (PT) is a perceived sound synchronous with the heartbeat without any external stimulus and is attributed to arterial and venous causes. [ 1 2 3 ] Venous PT is more common than arterial PT and is caused by numerous vascular anomalies and variants; surgical and endovascular interventions have proven successful for some lesions. [ 1 4 5 6 7 8 9 ] It is important to distinguish these anomalies or variants on imaging to determine the appropriate treatment strategy.…”

[ 1 4 5 6 7 8 9 ] It is important to distinguish these anomalies or variants on imaging to determine the appropriate treatment strategy. Thus far, previous studies on the incidence of these anomalies and variants of venous PT have notable limitations; they used small sample sizes and did not include several recently described venous PT anomalies, such as a dehiscent sigmoid plate and petrosquamosal sinus.…”
