“…Furthermore, alterations in (i) blood viscosity, (ii) red cell deformability, and (iii) platelet aggregation have been hypothesized to be responsible for localized acute ischemic events in the inner ear [ 4 , 5 ]. Among the possible causes of sudden sensorineural hearing loss (SSNHL) [ 6 ], the vascular hypothesis (ischemic or haemorrhagic) is among the most acknowledged, as micro-thromboembolism or micro-haemorrhage of the internal auditory artery are considered possible causes of acute cochlear damage [ 7 , 8 , 9 ]. For this reason, the link between hearing loss and hypercoagulable states and bleeding diathesis has been investigated already.…”

Hearing Loss and Blood Coagulation Disorders: A Review

A relationship between microvascular disorders and sensorineural hearing loss (SNHL) has been widely proposed. The vascular hypothesis, theorized for the onset of sudden SNHL (SSNHL), is among the most acknowledged: a localized acute cochlear damage, of ischemic or haemorrhagic nature, could be considered a causative factor of SSNHL. The aim of this review is to assess (i) the effect on hearing in patients affected by blood coagulation disorders (prothrombotic or haemorrhagic) and (ii) the possible etiopathogenetic mechanisms of the related hearing loss. A PRISMA-compliant review was performed. Medline, Embase, and Cinahl databases were searched from inception to 31 January 2023, and a total of 14 studies have been included in the review. The available data suggest that it is possible to consider clotting disorders as a potential condition at risk for sensorineural hearing loss; in particular, coagulation tests and eventually the assessment of genetic and acquired prothrombotic factors should be recommended in patients with SSNHL. Also, an audiological evaluation should be recommended for patients with blood coagulation disorders presenting cochlear symptoms, especially in those suffering from clotting diseases.

Background The gold-standard assessment of asymmetric sensorineural hearing loss (ASNHL) is contrast-enhanced MRI. Although rates of identifying a vestibular schwannoma are low (<5%), it is generally accepted as cost-effective. Yet, the impact of incidentalomas is rarely considered. This study aims to characterize the incidence of incidentalomas in the workup of ASNHL and quantify the associated socioeconomic burden. Study Design Retrospective cohort study. Setting Single academic institution in a midsized city in the United States. Methods Radiology records were queried for MRI's ordered for ASNHL between January 2012 and November 2022. Results were characterized as “group 1: normal,” “group 2: abnormal read/normal variant,” “group 3: abnormal—likely cause of ASNHL,” or “group 4: abnormal—follow-up needed.” Subsequent costs of workup for group 4 were estimated using Medicare Physician Fee Schedule for Medicare costs, US Congressional Budgeting Office data for private insurer costs, and USC-Brookings Schaeffer Initiative for Health Policy estimates for uninsured individuals. Results Six hundred patients met the inclusion criteria. Eighteen (3.0%) were categorized in group 3, whereas 40 (6.7%) were categorized in group 4. Of these patients, 7.5% (n = 3) had interventions to manage their incidental findings. Estimated per patient cost for further workup of incidental findings amounted to approximately $744, $1,534, and $2,260 for Medicare, private insurance, and uninsured costs, respectively. Conclusion Incidentalomas occur over twice as often as retrocochlear pathologies responsible for ASNHL. Although the number of patients requiring treatment for incidentaloma is low, the economic impact is not insubstantial and should be considered for both individual patients and health system payers.
