Acoustic Neuroma, also referred to as vestibular schwannoma, is a tumor that is non-malignant (not cancerous) and arises on the eighth cranial nerve. This nerve is responsible for conveying balance and sound data from the inner ear to the brain and is also known as the vestibulocochlear or auditory-vestibular nerve.
It arises from a specific type of cell called Schwann cells, which form the protective covering (myelin sheath) around the nerves. These tumors grow slowly and usually originate from the Schwann cells lining the vestibular portion of the eighth cranial nerve.
Epidemiology
The epidemiology of Acoustic Neuroma:
Incidence and Prevalence: Acoustic Neuroma are uncommon growths, comprising approximately 8-10% of all tumors within the skull. It is approximated that there are 1 to 2 instances of this condition per 100,000 people annually.
Age distribution: Although Acoustic Neuroma may develop at any point in time, they are typically identified in individuals aged 30 to 60 years. The highest occurrence of cases is frequently observed during the fifth and sixth decades of life.
Sporadic vs. hereditary cases: Acoustic Neuroma are sporadic, occurring without any known genetic predisposition. Approximately 5-10% of cases are associated with a condition called neurofibromatosis type 2 (NF2), an inherited disorder characterized by the development of tumors in the nervous system.
Anatomy
Pathophysiology
The pathophysiology of Acoustic Neuroma involves the abnormal growth of Schwann cells on the eighth cranial nerve, which is responsible for transmitting sound and balance information from the inner ear to the brain.
Proliferation of Schwann cells: Acoustic Neuroma arises from Schwann cells, which usually offer backing and safeguarding to nerve fibers.
Loss of tumor suppressor genes: In certain instances, the formation of Acoustic Neuroma might be linked with the depletion or deactivation of definite tumor suppressor genes.
Compression and displacement: As the Acoustic Neuroma grow, it can exert pressure on surrounding structures, including the adjacent cranial nerves, brainstem, and blood vessels. This compression can cause various symptoms, such as hearing loss, balance problems, facial numbness or weakness, and headaches.
Impaired nerve function: The tumor can disrupt the normal functioning of the affected cranial nerve. In the case of Acoustic Neuroma, the vestibulocochlear nerve is affected, leading to hearing loss, tinnitus, and balance disturbances.
Etiology
Tumor growth and compression: Acoustic Neuroma usually proliferate at a gradual pace and as they expand in size, they can put pressure on neighboring formations, such as the contiguous cranial nerves, brainstem, and blood vessels. The exact indications are determined by the location and magnitude of the tumor.
Disruption of nerve function: The growth disrupts the typical operation of the vestibulocochlear nerve. The pressure applied by the tumor on the nerve fibers hinders the transfer of auditory and equilibrium signals to the brain.
Angiogenesis: As the tumor expands, it stimulates the emergence of fresh blood vessels to furnish oxygen and nutrients for its heightened metabolic necessities. This angiogenesis can contribute to the advancement and expansion of the tumor.
Genetics
Prognostic Factors
Several prognostic factors can help predict the outcome and guide the management of Acoustic Neuroma. These factors provide insights into the tumor’s behavior, growth pattern, and the potential impact on a patient’s quality of life.
Size of tumor: The magnitude of the Acoustic Neuroma during detection is a crucial indicator of future outcomes. The smaller growth usually has a positive prognosis and is linked to a reduced risk of complications.
Auditory condition: The hearing condition before surgery is a vital indicator of future outcomes, particularly for patients with functional hearing. The conservation of hearing is contingent on the magnitude, positioning of the growth, and the surgical method used.
Facial nerve function: The status of the facial nerve, which controls the muscles of facial expression, is another important prognostic factor. Preservation of facial nerve function and avoidance of facial nerve injury during tumor removal surgery.
Age: The age of diagnosis may impact the prognosis of Acoustic Neuroma. Typically, younger patients experience more favorable outcomes due to fewer comorbidities and better overall health.
Clinical History
CLINICAL HISTORY
Age Group:
Acoustic Neuroma may emerge at any stage of life, though they are generally identified in grown-ups ranging from 30 to 60 years old. The highest frequency of acoustic tumors typically arises during the fifth and sixth decades of existence.
Acoustic Neuroma are rare in younger individuals, particularly those below 18 years of age. When children experience acoustic tumors, they are usually connected to genetic disorders like neurofibromatosis type 2 (NF2).
Physical Examination
PHYSICAL EXAMINATION
Otoscopy: The medical practitioner will employ an otoscope to inspect the outer ear and ear canal. This evaluation assists in eliminating other ear ailments and evaluating the general well-being of the ear.
Audiometry: A hearing examination, such as pure-tone audiometry, is carried out to assess the patient’s hearing capacity. This procedure measures the patient’s hearing levels at various pitches and helps to establish the degree of hearing loss, particularly in the impacted ear.
Neurological examination: A comprehensive neurological examination is conducted to evaluate other neurological functions. This may include assessing muscle strength, reflexes, sensation, and coordination.
Age group
Associated comorbidity
Associated Comorbidity or Activity:
Some of the commonly observed comorbidities in Acoustic Neuroma include:
Auditory impairment and tinnitus: Acoustic Neuroma frequently exhibit indications associated with auditory impairment and ringing in the ears. These indications can have a considerable effect on the patient’s ability to communicate and their quality of life.
Cognitive and psychological impacts: Living with an Acoustic Neuroma and managing its associated symptoms can have psychological and cognitive effects. Patients may experience anxiety, depression, or cognitive difficulties due to the stress of the diagnosis.
Equilibrium and Coordination difficulties: As a result of the vestibular segment of the eighth cranial nerve being affected, Acoustic Neuroma can lead to equilibrium disruptions, vertigo, and difficulties with synchronization.
Facial nerve dysfunction: The facial nerve runs near the vestibulocochlear nerve, which is affected by Acoustic Neuroma.
Associated activity
Acuity of presentation
Acuity of Presentation:
Acute or immediate onset: Although less frequent, certain individuals may encounter an abrupt or immediate manifestation of symptoms. This can transpire if the tumor undergoes rapid expansion or if there is an abrupt alteration in its size or location.
Slow onset: In many cases, the indications of Acoustic Neuroma appear gradually over a period. Individuals may undergo a gradual hearing impairment in one ear, frequently accompanied by ringing in the ears. At first, these indications may be inconspicuous and remain unnoticed.
Asymptomatic: In certain cases, Acoustic Neuroma may be detected incidentally during imaging studies performed for unrelated reasons, such as a head CT or MRI.
Differential Diagnoses
DIFFERENTIAL DIAGNOSIS
Meniere’s syndrome: Meniere’s syndrome is a condition of the internal ear marked by repeated bouts of vertigo, hearing impairment, buzzing in the ear, and a sensation of pressure in the ear.
Benign paroxysmal positional vertigo (BPPV): BPPV is a frequent condition of the inner ear that causes short bouts of vertigo activated by specific head motions. It may give rise to symptoms such as lightheadedness, instability, and nausea.
Vertigo induced by Migraine: A few people who suffer from migraines can undergo episodes of dizziness and vertigo, frequently together with headache, nausea, and hypersensitivity to light and sound.
