Episodic vertigo was fully controlled in 26 patients one needing a labyrinthectomy 18 months later.
Vestibular nerve section. In humans the vestibular nerve transmits sensory information transmitted by vestibular hair cells located in the two otolith organs the utricle and the saccule and the three semicircular canals via the vestibular ganglion of scarpa. One procedure is called vestibular nerve sectioning. Retraction of the cerebellum part of the brain is.
Generally done in an attempt to eliminate recurrent attacks of vertigo. Hearing loss is expected and inevitable. A vestibular nerve sectionconsists of cutting the vestibular part of the cochleovestibular 8th cranial nerve.
Surgery is rarely used to treat it. As it is the most invasive and risky of the surgical procedures offered for this condition other options first considered. Abstract records are available on 27 patients who had vestibular nerve section between 1975 and 1987 giving a follow up time of 10 to 22 years with a mean of 16 years.
If all other therapies are exhausted and the patient s hearing is still useful in the affected ear then this surgery is considered. Middle fossa translabyrinthine retrolabyrinthine and retrosigmoid approach. The goal of destructive surgery is to stop the production of sensory information or prevent its transmission from the inner ear to the brain.
Vestibular nerve section can be accomplished through four approaches. This operation is considered in patients who have severe meniere s disease with attacks of vertigo that continue despite aggressive medical management and still have good hearing in the affected ear. Surgical procedures for peripheral vestibular disorders are either corrective or destructive.
The goal of corrective surgery is to repair or stabilize inner ear function. In this short series our aim was. Vestibular neurotomy is usually preferred in our center.
