A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
An acoustic neuroma is a schwannoma on the vestibular nerve in the brain. This nerve is involved in hearing and patients with vestibular schwannomas experience hearing loss. However, bilateral vestibular schwannomas (vestibular schwannomas on both sides of the brain) do not occur in schwannomatosis. Juvenile vestibular tumors do not occur ...
NF2 is a genetic disorder that is characterised by the development of non-cancerous tumours along the nervous system. These vestibular schwannomas (also known as acoustic neuromas) often form on the auditory nerve, and surgical removal of these NF2 tumours can damage the auditory nerve and limiting the patient's ability to hear.

This surgical approach is typically performed by a team of surgeons, including a neurotologist (an ear, nose, and throat surgeon specializing in skull base surgery) as well as a neurosurgeon. In this approach, the semicircular canals and vestibule , including the utricle and the saccule of the inner ear are removed with a surgical drill ...
The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80%), followed by meningioma (10%). The cranial nerves affected are (from most common to least common) : VIII (cochlear component), VIII (vestibular component), V Acoustic neuroma/vestibular schwannoma
NF2 is a genetically transmitted condition. Diagnosis is most common in early adulthood (20–30 years); however, it can be diagnosed earlier. NF2 can be diagnosed due to the presence of a bilateral vestibular schwannoma, or an acoustic neuroma, which causes a hearing loss that may begin unilaterally. [14]
Schwannomas of the head and neck are a fairly common occurrence and can be found incidentally in 3–4% of patients at autopsy. [4] Most common of these is a vestibular schwannoma, a tumor of the vestibulocochlear nerve that may lead to tinnitus and hearing loss on the affected side. Outside the cranial nerves, schwannomas may present on the ...
A vestibulectomy is a gynecological surgical procedure that can be used to treat vulvar pain, specifically in cases of provoked vestibulodynia. Vestibulodynia (vulvar vestibulitis) is a chronic pain syndrome that is a subtype of localized vulvodynia [1] where chronic pain and irritation is present in the vulval vestibule, which is near the entrance of the vagina.
