Vestibular nerve section, also known as vestibular neurectomy, is a surgical procedure performed to treat severe cases of vertigo and imbalance that do not respond to other forms of treatment. The procedure involves cutting the vestibular nerve, which is responsible for transmitting signals related to balance and spatial orientation from the inner ear to the brain.
Although vestibular nerve section can be highly effective in relieving symptoms of vertigo, there are potential complications associated with the procedure. One of the most common complications is hearing loss, as the vestibular nerve is located close to the cochlear nerve, which is responsible for hearing. In some cases, patients may experience partial or complete loss of hearing in the affected ear following vestibular nerve section.
Other complications of the procedure may include facial nerve damage, which can result in weakness or paralysis of the facial muscles on the affected side, as well as cerebrospinal fluid leakage, infection, and balance issues. It is important for patients considering vestibular nerve section to discuss the risks and benefits of the procedure with their healthcare provider and to weigh these factors carefully before making a decision. Like any surgical procedure, vestibular nerve section carries potential risks, and patients should be fully informed before proceeding with treatment.
Can the vestibular nerve be repaired?
Surgical procedures for peripheral vestibular disorders are either corrective or destructive. The goal of corrective surgery is to repair or stabilize inner ear function. The goal of destructive surgery is to stop the production of sensory information or prevent its transmission from the inner ear to the brain.
What is the success rate of vestibular neurectomy?
Vestibular neurectomy is considered the reference treatment for incapacitating vertigo accompanying Meniere’s disease with an efficiency rate of 85-95% in most literature reports. Up to 95% of vestibular neurectomies cure vertigo.
What are the complications of vestibular neurectomy?
Tinnitus (ringing in ears): Tinnitus may remain, disappear, or get worse. Dizziness: Severe dizziness, vertigo, and imbalance are common immediately following surgery due to cutting of the balance nerve. After a few days, vertigo spinning stops, and imbalance improves slowly over weeks to months.
What is the success rate for vestibular nerve section?
Vestibular nerve section is very effective. More than 90% of patients will have complete relief of their vertigo. Hearing is preserved at the preoperative level about 80% of the time.
