Is Sudden Sensorineural Hearing Loss (SSNHL) Hereditary?

Sudden sensorineural hearing loss (SSNHL), also known as idiopathic sudden hearing loss, refers to a rapid onset of sensorineural hearing impairment with no identifiable cause. Its primary clinical manifestations include unilateral hearing loss, often accompanied by tinnitus, aural fullness, vertigo, nausea, and vomiting. So, is sudden sensorineural hearing loss hereditary? Below, we address this question.

Is Sudden Sensorineural Hearing Loss Hereditary?

Generally, sudden sensorineural hearing loss is not hereditary. It falls under the category of sensorineural hearing loss, and its precise etiology remains unclear. Current understanding suggests it may be associated with factors such as physical exhaustion, exposure to cold, or emotional stress (e.g., anger).

Therefore, individuals should prioritize adequate rest, avoid excessive fatigue and sleep deprivation, maintain stable and positive emotional states, and minimize adverse psychological stimuli—such as anxiety or intense anger—that may trigger liver-fire ascending to impair auditory function. Ear hygiene should also be emphasized: keep the external auditory canal clean and dry, and avoid frequent ear cleaning or probing to prevent infection.

Additionally, glucocorticoids may be administered under medical supervision. These agents possess anti-inflammatory, antiviral, and immunosuppressive properties, helping alleviate vascular endothelial edema and improve cochlear blood supply—making them a cornerstone in current SSNHL treatment.

Thrombolytic and anticoagulant agents are also used. Studies show that patients with SSNHL exhibit significantly elevated plasma fibrinogen levels compared with healthy controls, along with increased red blood cell aggregation and plasma viscosity—indicating that blood hyperviscosity plays an important role in the pathogenesis of SSNHL.
