The vestibulocochlear face , also known as auditory vestibular nervus , is the 8th cranial nervus and is responsible for keep proportion and sense of hearing in a patient role . This special sensory nervus has two nerve branches , the vestibular limb and the cochlear branch . The vestibular offset facilitate with the equilibrium command of a someone , aid a person conserve an upright posture and ascertain their spatial positioning . The role of the cochlear branch is to serve the brain to detect sound which is transmitted through vibrations in hair cells . Damage to vestibulocochlear nerve impairs the mortal ’s ability to maintain equilibrium and to hear . There are various factors which damage the vestibulocochlear nerve .
What are the Causes of Nerve Damage in the Ear?
Some of the common causes of cheek damage in the spike are :
Infection
The sensory cheek endings ( tomentum cells ) of the vestibulocochlear cochlear mettle can get damage by pinna transmission . The most common type of pinna contagion isotitis media , which is the middle capitulum infection . Another contagion is vestibular neuronitis where there is inflammation of the vestibular part of the vestibulocochlear nerve causing symmetry disorder in the patient . Infections in children , such asmeasles , mumpsandchickenpox , can also get nerve equipment casualty in the ear .
Trauma
Trauma or accidental injury to the head which causes skull fracture can make damage to the vestibulocochlear nerve . The vestibulocochlear nerve exits through the temporal bone from the brain and passes into the internal acoustic meatus and gets divided into two branches . hurt to the temporal bone can also cause impairment to the vestibulocochlear nerve resulting in impairment of balance and hearing .
Excessive Noise
Noise pollution , such as exposure to tacky music either over a period of time or suddenly , can cause nerve damage in the ear and result in discover loss . Excessive and persistent noise damages the nerve termination present in the internal auricle which can top to lasting hearing loss . face damage in the pinna can also cause tinnitus , which is a status where the patient feels persistent ringing in the ears .
Tumors
Brain tumorsor tumor of the skull can also cause damage to the vestibular or acoustic branch of the vestibulocochlear nervus . Acoustic neuromais a noncancerous growth cogitate to pass off as a resultant of familial factors . This neoplasm can prepare in vestibular share of the mettle and is also termed as vestibular schwannoma . Some of the common symptoms of Acoustic neuroma includebalance disorders , get a line lossandtinnitus .
Treatment of Nerve Damage in the Ear
discussion depends on the suit of the face damage and can include the function of medicine , OR andhearing aids .
