What type of hearing loss is associated with Sudden Idiopathic SNHL?

Sudden Idiopathic Sensorineural Hearing Loss (SNHL) is characterized by a rapid onset of hearing loss, often described as occurring over a period of 72 hours or less. This condition primarily affects one ear, which aligns with the choice indicating unilateral hearing loss.

Unilateral hearing loss refers to hearing impairment in only one ear, and Sudden Idiopathic SNHL typically presents this way, leaving the other ear unaffected. In contrast, bilateral hearing loss involves both ears, which does not fit the typical presentation of this specific type of hearing loss.

Conductive hearing loss, on the other hand, involves a problem in the outer or middle ear that prevents sound from being conducted to the inner ear, which differs fundamentally from the sensorineural nature of Sudden Idiopathic SNHL. Mixed hearing loss refers to a combination of conductive and sensorineural hearing loss and, while possible in other contexts, is not characteristic of Sudden Idiopathic SNHL, since it specifically involves the inner ear's functionality.

Thus, the correct type of hearing loss associated with Sudden Idiopathic SNHL is unilateral hearing loss, marking it as the focus of this specific condition.
