What Researchers Did
Researchers conducted a review to synthesize current understanding of inner ear anatomy, clinical features, and treatment strategies for idiopathic sudden sensorineural hearing loss (ISSNHL), with a focus on vascular pathologies.
What They Found
They found that vascular pathologies, such as cochlear ischemia or infarction, are highly probable causes of ISSNHL, given that the labyrinthine artery is the sole end artery supplying the inner ear. Occlusion of the vestibulo-cochlear artery (VCA), which courses through a narrow bone canal, is a significant factor, and ISSNHL diagnosis typically involves excluding retrocochlear pathologies like vestibular schwannoma.
