Summary
This study found no link between vertebrobasilar vascular system laterality and idiopathic sudden sensorineural hearing loss (ISSNHL) side. Patients with a potential vascular match were older but showed no other distinct clinical or hearing loss features.
Area of Science:
- Neurology
- Otolaryngology
- Vascular Imaging
Background:
- The cause of idiopathic sudden sensorineural hearing loss (ISSNHL) is unknown, but vascular issues are suspected.
- This study investigates if the side of the vertebrobasilar vascular system relates to the side of ISSNHL.
Purpose of the Study:
- To determine the correlation between vertebrobasilar vascular system laterality (VBVSL) and the laterality of idiopathic sudden sensorineural hearing loss (ISSNHL).
Main Methods:
- Retrospective analysis of 191 ISSNHL patients diagnosed between 2015-2020.
- Vertebrobasilar vascular system laterality (VBVSL) assessed using MRI scans.
- Defined 'positive match' as ISSNHL contralateral to basilar artery curvature or ipsilateral to dominant vertebral artery.
Main Results:
- Most patients (63.4% for BA, 71.2% for VA) did not have a positive vascular match.
- Patients with a positive match for vertebral artery (VA) laterality were significantly older.
- No significant differences in clinical, audiometric, or outcome factors were found between matched and unmatched groups.
Conclusions:
- No association was found between vertebrobasilar vascular system laterality and ISSNHL laterality.
- Patients with a positive vascular match did not present with unique clinical or audiometric characteristics.

01:28Major Somatic Sensory Pathways
992
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

01:29The Vestibular System
39.6K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:15Equilibrium and Balance
4.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:28Lateralization
342
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

01:15Auditory Pathway
5.4K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:13The Cochlea
45.1K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
