Summary
Vertigo in sudden sensorineural hearing loss (SSNHL) is linked to vestibular dysfunction, but this relationship changes after considering audiogram configurations. Audiogram patterns are crucial for understanding vestibular involvement in SSNHL patients experiencing vertigo.
Area of Science:
- Otolaryngology
- Neurology
- Vestibular System Research
Background:
- Sudden sensorineural hearing loss (SSNHL) can present with or without vertigo.
- The extent of vestibular end organ (VEO) involvement in SSNHL and its correlation with vertigo symptoms require further elucidation.
- Audiogram classification may influence the understanding of vestibular dysfunction in SSNHL.
Purpose of the Study:
- To investigate the relationship between vertigo and vestibular dysfunction in unilateral SSNHL.
- To assess the contribution of audiogram classification to this relationship.
- To correlate vestibular function test results with clinical presentation and prognosis.
Main Methods:
- Retrospective analysis of 50 unilateral SSNHL patients, divided into vertigo and non-vertigo groups.
- Vestibular function tests included video head impulse test (vHIT), cervical vestibular-evoked myogenic potential (cVEMP), and ocular VEMP (oVEMP).
- Analysis of audiogram configurations, initial pure-tone average (PTA), number of involved VEOs, and prognosis.
Main Results:
- Significant differences in initial audiogram configurations and abnormal rates of posterior semicircular canal (PSC) and oVEMP were observed between groups.
- The number of involved VEOs correlated with initial PTA in both vertigo and non-vertigo groups.
- Prognosis was related to cVEMP abnormalities and VEO involvement, particularly to audiogram configurations in the vertigo group.
Conclusions:
- The association between vestibular dysfunction and vertigo in SSNHL differs based on audiogram classification.
- Audiogram configuration is a critical factor when evaluating vestibular dysfunction in SSNHL patients with vertigo.
- Further attention to audiogram patterns is recommended for comprehensive assessment of vestibular involvement in SSNHL.

5.3K
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...

01:29The Vestibular System
41.9K
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.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

01:17Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

01:13The Cochlea
48.2K
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.

01:15Auditory Pathway
6.2K
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.
