		The central branches leave the trunk of the facial nerve in the internal acoustic meatus, and form the sensory root; the peripheral branches are continued into the chorda tympani and greater superficial petrosal nerves.
		Entering the brain at the lower border of the pons between the motor root and the acoustic nerve, the fibers of the sensory root pass into the substance of the medulla oblongata and end in the upper part of the terminal nucleus of the glossopharyngeal nerve and in the fasciculus solitarius.
		From their superficial attachments to the brain, the two roots of the facial nerve pass lateralward and forward with the acoustic nerve to the internal acoustic meatus.

		—The cochlear nerve or root, the nerve of hearing, arises from bipolar cells in the spiral ganglion of the cochlea, situated near the inner edge of the osseous spiral lamina.
		In the upper part of the lateral lemniscus there is a collection of nerve cells, the nucleus of the lateral lemniscus, around the cells of which some of the fibers arborize and from the cells of which axons originate to continue upward the tract of the lateral lemniscus.
		—The vestibular nerve or root, the nerve of equilibration, arises from bipolar cells in the vestibular ganglion, ganglion of Scarpa, which is situated in the upper part of the outer end of the internal auditory meatus.

	Acoustic Neuroma
		An acoustic neuroma (sometimes called a neurinoma or vestibular schwannoma) is a benign (non-cancerous) tissue growth that arises on the eighth cranial nerve.
		The acoustic nerve arises from a part of the brainstem called the pons (in a region referred to as the cerebellopontine angle).
		The acoustic portion of the eighth nerve goes to the cochlea of the ear and transmits hearing while the vestibular portion goes to the semicircular canals which are responsible for detecting motion (acceleration more technically) and hence are involved in the sense of balance.

	ACOUSTIC NEUROMA
		Acoustic neuromas are a rare cause of unilateral hearing loss as well as other symptoms related to the ear and brain.
		Acoustic neuromas, also known as vestibular schwannomas, are non-malignant tumors of the 8th cranial nerve.
		The smallest, the intracanalicular acoustic, is measured in mm.

	Acoustic Neuroma \| Principal Health News
		An acoustic neuroma is a benign tumor involving cells of the myelin sheath that surrounds the vestibulocochlear nerve (eighth cranial nerve).
		The vestibulocochlear nerve extends from the inner ear to the brain and is made up of a vestibular branch, often called the vestibular nerve, and a cochlear branch, called the cochlear nerve.
		Acoustic neuromas are often called vestibular schwannomas because they are tumors that arise from the myelin sheath that surrounds the vestibular nerve.

		The etiology of facial nerve injury is discussed with emphasis on the pathophysiology of facial nerve palsy.
		Acoustic neuromas are considered by many surgeons to be one of the most difficult brain tumors to remove without producing dysfunction;[16,18,19] successful removal has long been considered a neurosurgical tour de force.
		According to the Acoustic Neuroma Association, facial nerve dysfunction remains the number one concern among patients undergoing cerebellopontine angle surgery.[35,40,47] Given the functional and psychological effects of facial nerve dysfunction, it is important to identify perioperative factors that influence facial nerve outcome.

	acoustic neuroma glossary
		ACOUSTIC NEUROMA - a benign tumor derived from the schwann cells lining the acoustic nerve (or vestibulocochlear nerve); more accurately known as "vestibular schwannoma" since the tumor is most often derived from schwann cells of the vestibular portion of this nerve.
		In acoustic neuroma surgery, the sigmoid sinus must be exposed (suboccipital approach goes behind the sigmoid sinus and translabyrinthine approach goes in front of the sigmoid sinus).
		The facial and vestibulocochlear nerves travel through canals in the temporal bone, and removal of portions of the temporal bone is necessary for acoustic neuroma surgery.

	Acoustic Neuroma \| Mayfield Clinic
		Acoustic tumors that are small and have few symptoms may be observed with routine MRI scans every year until the tumor growth or symptoms necessitate surgery.
		Acoustic tumors, depending on their size, can be attached to the seventh nerve, fifth nerve, ninth nerve, brainstem, or the anterior inferior cerebellar artery.
		Tumor attachment to the seventh nerve is carefully dissected to preserve the nerve because the seventh nerve is responsible for facial movement.

	Acoustic Neuroma - Origin
		An acoustic neuroma (sometimes also termed a neurinoma or vestibular schwannoma) is a benign or non-cancerous growth that arises from the 8th or vestibulo-cochlear nerve.
		Acoustic neuromas usually arise from the cells of the VIII nerve within the internal auditory canal (third figure).
		The 7th nerve is gradually stretched into a ribbon like structure over the enlarging tumor (figure; cross section of the 7th nerve is shown in the right half of the figure).

	ACOUSTIC NEUROMA
		Acoustic neuromas are a rare cause of unilateral hearing loss, dizziness, as well as rarely other symptoms related to the brain.
		In spite of the usual origin of acoustics in the inferior vestibular nerve (Komatsuzaki and Tsunoda, 2001), vertigo (spinning) is not common, occurring in only about 20 percent of persons with acoustic neuroma.
		As the inferior vestibular nerve innervates the posterior semicircular canal and saccule, one might expect VEMP's, which test saccule function, to be uniformly abnormal in acoustic neuroma's, but this has not yet been studied.

	Acoustic Neuroma
		Acoustic Neuroma is a benign (non-cancerous) growth that begins at the 8th cranial nerve, which runs from the brain to the inner ear.
		The 8th cranial nerve is double barreled; one part deals with hearing and the other with balance and the body’s sense of position in space.
		The trigeminal nerve (5th cranial nerve) is responsible for sensation on the skin of the face and the surface of the eye; if the 5th cranial nerve becomes involved it may lead to facial numbness.

		Referring to cranial nerves usually in conjunction with a procedure to "splice" the 7th and 12th nerves to help repair facial function to the 7th (facial) nerve.
		Since acoustic neuroma usually arises on the vestibular branch of the VIIIth cranial nerve, it is often (and according to some, properly) referred to as vestibular schwannoma.
		The facial nerve is the seventh cranial nerve.

		Immediately associated with these nerves is the 7th cranial nerve, the nerve that controls the muscles of the face, salivation, tearing, and taste.
		In cases of large tumors with a thinned out nerve that is splayed over the surface of the tumor, the nerve is physically saved during surgery, but it may not function well or only partially recover.
		In cases of partial dysfunction to the nerve, electrical stimulation to the face may allow the facial muscles to stay in shape while the nerve repairs itself.

	Archives of Pathology & Laboratory Medicine: Lipochoristomas (lipomatous tumors) of the acoustic nerve
		Context.-Lipochoristomas (lipomatous choristomas) are rare tumors of the acoustic nerve (cranial nerve VIII/vestibulocochlear nerve) within the internal acoustic canal and sometimes the cerebellopontine angle, and are histogenetically believed to be congenital malformations.
		Neoplasms of the internal acoustic canal (IAC) and cerebellopontine angle (CPA) often involve the acoustic nerve (cranial nerve VIII [CNVIII]/vestibulocochlear nerve).
		The vast majority are of neuroepithelial nosology, comprised mostly of acoustic schwannomas (approximately 80%-90%) and meningiomas (approximately 10%),1-4 while uncommon tumors include epidermoid/dermoid cysts, arachnoid cysts, and a variety of rare benign and malignant neoplasms.

		A series of nerve grafts may be done, followed by a muscle transplant followed shortly after by the nerve connection.
		The important thing is to understand that facial nerve function is not a question of "it works fine" vs. "it doesn't work at all" -- there is a whole range of "paresis" that can go from "not noticeable normally" to "full loss of funtion".
		If thee is loss of facial nerve function, it can be hard because of appearance, it can be difficult because of function (if the entire face is numb it is hard to chew without biting oneself), and because of the risk of permanent damage (if an eye becomes too dry serioius damaage could occur.
