acoustical neuroma is a benignant Cancer the Crab of the eighth cranial nerve . It is a slow - uprise tumor . It does not grow in the brain but it may compress the brain when it grows big . Its symptom involve exit of hearing , ringing in the ear , vertigo , facial numbness , release of body remainder and many others . It is find by hearing test and an MRI scan . It is treated with insomniac monitoring , radioactivity therapy , and surgery .
What Are The First Symptoms Of Acoustic Neuroma?
Acoustic neuroma is a non - cancerous tumor that develop on the vestibular nerve ( eighth cranial nerve ) . This nerve is also known as the vestibulocochlear nerve that conduct sounds from the inner ear and sends the information of counterweight from the inner pinna to the brain . This Cancer the Crab is known as vestibular schwannoma . Usually , it strike one ear . Its emergence is slow and may take years to develop . It does not develop in the brain . It may grow large that may compact the brain and neighboring cranial nerve . Then , it may upset the functions of facial muscles and grammatical construction and sensations . If tumors become too big , it contract the brain root word and cerebellum that can be fatal.(1 )
The symptoms of acoustical neuroma are often not noticeable . multitude often consider them as symptom of normal aging . It is sympathize only after diagnosis . It affects audience and equaliser nerves . Its symptom appear as the tumour grow.(1)Its first symptoms let in a obtuse and gradual release of find out in one of the ears . It is often assort with echo in the ear ( tinnitus ) and a sensation of fullness in the stirred spike . Sometimes , it may cause a sudden loss of hearing.(2 )
The other symptoms of acoustic neuroma involve-
Symptoms like clumsiness and confusion in the mind point the serious impact of the tumors on the brain , and it calls for immediate treatment.(1 )
acoustical neuroma is notice with a earreach test , MRI andCT CAT scan . A earshot test or auditory test is done by the audiologist to make up one’s mind your hearing ability . MRI scan determines the sizing of the neoplasm . If theMRI scanis not usable , then a CT CAT scan is performed to find out the exact localization of the neoplasm . However , an MRI CAT scan can encounter out even small tumors of size 1 to 2 millimeters in diameters.(4 )
Causes Of Acoustic Neuroma
The drive of acoustical neuroma are not unclouded . There are two character of acoustical sarcoma . One is sporadic form and the other is link up with a genetic upset named von Recklinghausen’s disease character II . The sporadic form of acoustical neuroma does not have any specific movement known today . The only known risk ingredient for the sporadic figure is direct vulnerability to the high dose of radiation employ especially to the head and neck.(1 )
The case of acoustic neuroma link with von Recklinghausen’s disease type II is most commonly seen in adult above 30 age . it is an genetic disease that leads to the formation of tumors in the total skittish system . It usually affects both ears . It is uncommon among the two types of acoustical neuroma.(1 )
Conclusion
acoustical neuroma is a noncancerous neoplasm of the eighth cranial nerve . Its first symptom involve irksome auditory sense loss over a few years , with a ringing sound in the ear and fullness feel in one of the ears . It is detected with earreach tests , CT scan and MRI scans .
