Abstract
Most cases of sudden sensorineural hearing loss (SSNHL) occur without a specific identifiable cause, although vascular factors may serve as potential etiological contributors. Silent infarction refers to ischemic changes observed on imaging studies without accompanying clinical symptoms; however, this condition is clinically significant owing to the increased risk of future stroke. We report a case of left-sided SSNHL accompanied by dizziness in a 62-year-old male patient who was diagnosed with left pontine infarction without any other neurological symptoms. The cochlea and pons receive blood supply from the anterior inferior cerebellar artery; the cochlea lacks collateral vessels and is therefore susceptible to fluctuations in blood flow. This case report provides evidence to support the vascular hypothesis as the etiology underlying SSNHL.
期刊介绍:
Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
