Summary
Bilateral sequential vestibular neuritis (BSVN) is rare, affecting one ear then the other years later. Recovery varies, highlighting the need for careful diagnosis and management of this vestibular disorder.
Area of Science:
- Neurology
- Otolaryngology
- Vestibular System Disorders
Background:
- Bilateral sequential vestibular neuritis (BSVN) is an uncommon condition.
- Understanding its clinical course and recovery is essential for patient management.
Purpose of the Study:
- To characterize the clinical features, vestibular function, and recovery in patients with BSVN.
- To explore diagnostic challenges and pathophysiological aspects of BSVN.
Main Methods:
- Retrospective analysis of three male patients diagnosed with BSVN.
- Comprehensive vestibular assessments including caloric testing, video head impulse test (vHIT), and vestibular evoked myogenic potentials (VEMP) were performed during both episodes.
Main Results:
- Patients experienced contralateral vestibular neuritis after a 2-5 year interval.
- Two patients showed significant recovery, while one developed persistent bilateral vestibulopathy.
- The second attack typically presented with milder symptoms than the first.
Conclusions:
- BSVN exhibits peripheral recovery and central compensation.
- Sequential vestibular testing aids in understanding its diverse presentations and recovery.
- Early recognition is vital for diagnosis, counseling, and management.

01:29The Vestibular System
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
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...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
