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 ...
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.

Neurofibromatosis type II, in which bilateral acoustic neuromas (tumors of the vestibulocochlear nerve or cranial nerve 8 (CN VIII) also known as schwannoma) develop, often leading to hearing loss. [16] Schwannomatosis, in which painful schwannomas develop on spinal and peripheral nerves. [17]
Soon, with five people in the room—Townsell, her boyfriend, a patient-care advocate, the supervising doctor, and a doctor in training—the doctor used the Carevix to place her copper IUD.
However, “This systematic review of multiple studies showed that mobile phone use likely does not increase the risk of brain cancer, including gliomas, meningiomas, and acoustic neuromas,” she ...
The misnomer of acoustic neuroma is still often used. The vestibular schwannomas grow slowly at the inner entrance of the internal auditory meatus (meatus acousticus internus). They derive from the nerve sheaths of the upper part of the nervus vestibularis in the region between the central and peripheral myelin (Obersteiner-Redlich-Zone) within ...
Retrograde discharge happens when semen flows backward from the urethra to the bladder due to problems with the bladder neck muscle. The bladder neck muscle is also sometimes called the bladder ...
Neurotology is expanded to include surgery of the lateral skull base to treat intracranial tumors related to the ear and surrounding nerve and vascular structures, such as large cerebellar pontine angle acoustic neuromas, glomus jugulare tumors and facial nerve tumors. Some of the concerns of otology include:
