“…has reported reversible bilateral sensorineural hearing loss in a woman with cerebral venous thrombosis whose hearing loss reversed with treatment of intracranial hypertension. [3] There are different explanation for VIII nerve dysfunction in CVT. Increased pressure in the subarachnoid space may be transmitted to the endolymphatic system via cochlear aqueduct and the perilymph.…”

“…Increased intracranial pressure may also disturb VIII nerve function by causing increased pressure in its meningeal sheath. [3] However, CVT has also been referred as a direct cause of hypoacusis, in the absence of increased intracranial pressure. Cochlear venous blood is collected by cochlear vein and drains through labyrinthine vein into the inferior petrosal sinus or directly into transverse sinus.…”

Cerebral venous thrombosis (CVT) is a well-recognized entity, but its clinical presentation is varied and often mimics many neurological disorders, making it a diagnostic challenge. Cerebral venous thrombosis has a wide spectrum of signs and symptoms, which may evolve suddenly or over weeks. It mimics many neurological conditions such as meningitis, encephalopathy, idiopathic intracranial hypertension, and stroke. Cerebral venous thrombosis presenting as multiple lower cranial nerve palsies, are rarely reported. We describe a pregnant lady who presented with sensorineural deafness of the right ear and paralysis of the 9th, 10th, and 12th cranial nerves on the right side. She was diagnosed to have thrombosis of the right transverse sinus and sigmoid sinus with extension to the jugular vein and confluence of sinuses. She improved with anticoagulant treatment.

“…Reduced cochlear blood flow due to venous insufficiency is another theoretical mechanism by which vascular impairment can induce cochlear dysfunction. Cerebral venous thrombosis, chronic cerebrospinal insufficiency, and hyperviscosity occurring in macroglobulinemia are known causes of reversible SSHL 12,31,32 . In addition, Gatehouse et al 33 reported a significant relationship between hyperviscosity and sensorineural hearing loss.…”

Although cochlear venous insufficiency has been considered to cause sudden sensorineural hearing loss (SSHL), there is insufficient clinical evidence to support this hypothesis. We sought to determine whether there is a correlation between draining patterns of the dural venous sinuses and the side of the affected ear in SSHL, as well as hearing recovery. The medical records of 109 patients diagnosed with unilateral SSHL were retrospectively reviewed. Magnetic resonance images and pure tone audiometry were performed in all patients. We measured the dominance of the inferior petrosal sinus (IPS) and transverse-sigmoid sinus (TS/SS) ipsilateral to the affected ear. Most patients were characterized by asymmetric venous drainage (IPS, 53.2%; TS/SS, 81.7%). The dominant side of the IPS or TS/SS was independent of the side of the affected ear for all patients in this study. However, in 35 patients with early recovery within 2 weeks, the dominant side of TS/SS was significantly associated with the side of the affected ear (p = 0.011). Moreover, the dominance of both the IPS and TS/SS influenced hearing outcomes at 3 months. Dominant TS/SS ipsilateral to the affected ear, particularly in the presence of ipsilateral hypoplastic IPS, is associated with a favorable hearing prognosis of SSHL. Sudden sensorineural hearing loss (SSHL) is frequently associated with idiopathic etiology. Several theories concerning causes of SSHL have been proposed, including viral infection and autoimmune disease. Disruption of cochlear blood flow has also been considered as one of the factors explaining the potential pathophysiology of SSHL 1. Studies using an animal model have provided evidence to support vascular impairment as a possible cause of SSHL, since it is not possible to directly measure or visualize small amounts of blood flow in the cochlea using current techniques in humans 1. Similar to retinal vein occlusions, impaired venous return from the cochlear circulation is suspected to cause inner ear disorders 2. However, there are fewer experiments investigating the effect of venous congestion produced in the cochlea, compared to the number of experiments involving occlusion of arteries to the cochlea 2,3. The inferior cochlear vein (ICV) is the main draining vein of the cochlea. The ICV runs within the canal of Cotugno proximal to the cochlear aqueduct. Considering the venous drainage of the cochlea into the dural sinus, anatomic variability of adjacent sinuses, including the inferior petrosal sinus (IPS), transverse-sigmoid sinuses (TS/SS), or the jugular bulb, may affect the venous drainage of the cochlea and the development of hearing impairment. This theory of venous congestion is supported by the fact that the dural sinuses frequently have asymmetric drainage in the normal population. Prior studies have demonstrated that 23-35% and 72% of cases presented asymmetric structure of the IPS and TS/SS, respectively 4. In addition, there have been radiological studies showing significant asymmetry of the jugular bulb 5. Contrast-enhance...

“…Kim et al reported CVT mimicking acute unilateral vestibulopathy [25]. Assessment by MRI identified extensive CVT involving the superior longitudinal sinus, the straight sinus, and the proximal portion of both transverse sinuses in a patient with CVT sustained reversible bilateral sensorineural hearing loss [26]. Crassard et al described a patient with lateral sinus thrombosis who presented with acute hearing loss without vertigo or imbalance.…”

Auditory Dysfunction in Patients with Cerebrovascular Disease

Auditory dysfunction is a common clinical symptom that can induce profound effects on the quality of life of those affected. Cerebrovascular disease (CVD) is the most prevalent neurological disorder today, but it has generally been considered a rare cause of auditory dysfunction. However, a substantial proportion of patients with stroke might have auditory dysfunction that has been underestimated due to difficulties with evaluation. The present study reviews relationships between auditory dysfunction and types of CVD including cerebral infarction, intracerebral hemorrhage, subarachnoid hemorrhage, cerebrovascular malformation, moyamoya disease, and superficial siderosis. Recent advances in the etiology, anatomy, and strategies to diagnose and treat these conditions are described. The numbers of patients with CVD accompanied by auditory dysfunction will increase as the population ages. Cerebrovascular diseases often include the auditory system, resulting in various types of auditory dysfunctions, such as unilateral or bilateral deafness, cortical deafness, pure word deafness, auditory agnosia, and auditory hallucinations, some of which are subtle and can only be detected by precise psychoacoustic and electrophysiological testing. The contribution of CVD to auditory dysfunction needs to be understood because CVD can be fatal if overlooked.
