Summary
Vestibular nerve section effectively controls vertigo in most patients. However, long-term hearing significantly deteriorates, especially in those with initially good hearing, and carries risks of facial nerve issues.
Area of Science:
- Neurosurgery
- Otolaryngology
- Audiology
Background:
- Vestibular nerve section is a surgical treatment for severe vertigo.
- Long-term outcomes, particularly regarding hearing and potential complications, require thorough investigation.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of vestibular nerve section.
- To assess the impact of vestibular nerve section on hearing and tinnitus over time.
Main Methods:
- Retrospective analysis of 27 patients undergoing vestibular nerve section (1975-1987).
- Long-term follow-up (10-22 years) assessing vertigo control, hearing thresholds, tinnitus, and facial nerve function.
Main Results:
- Episodic vertigo was controlled in 26 of 27 patients.
- Significant hearing deterioration observed over 20 years, averaging a 29 dB loss.
- Hearing loss was more pronounced in patients with better pre-operative hearing.
- Tinnitus worsened in some patients; facial nerve complications occurred in two patients.
Conclusions:
- Vestibular nerve section provides excellent long-term vertigo control.
- Progressive hearing loss is a significant long-term consequence, necessitating careful patient selection and counseling.
- Potential for contralateral ear involvement and facial nerve injury should be considered.

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.
01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

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...
