The treatment for vestibular neuronitis depends on the cause. However, symptoms of vertigo can be treated in the same way as other vestibular dysfunctions with vestibular rehabilitation.

In most cases, the condition tends to be self-limiting. In 95% or greater, vestibular neuritis is a one-time experience with most people fully recovering.

Recovery from acute labyrinthine inflammation generally takes from one to six weeks, but it is not uncommon for residual symptoms (dysequilibrium and/or dizziness) to last for a couple of months.

Recovery from a temporary damaged inner ear typically follows two phases:

1. An acute period, which may include severe vertigo and vomiting

2. approximately two weeks of sub-acute symptoms and rapid recovery

Tests for vertigo often attempt to elicit nystagmus and to differentiate vertigo from other causes of dizziness such as presyncope, hyperventilation syndrome, disequilibrium, or psychiatric causes of lightheadedness. Tests of vestibular system (balance) function include: electronystagmography (ENG), Dix-Hallpike maneuver, rotation tests, head-thrust test, caloric reflex test, and computerized dynamic posturography (CDP).

The HINTS test, which is a combination of three physical exam tests that may be performed by physicians at the bedside has been deemed helpful in differentiating between central and peripheral causes of vertigo. The HINTS test involves: the horizontal head impulse test, observation of nystagmus on primary gaze, and the test of skew. CT scans or MRIs are sometimes used by physicians when diagnosing vertigo.

Tests of auditory system (hearing) function include pure tone audiometry, speech audiometry, acoustic reflex, electrocochleography (ECoG), otoacoustic emissions (OAE), and the auditory brainstem response test.

A number of specific conditions can cause vertigo. In the elderly, however, the condition is often multifactorial.

A recent history of underwater diving can indicate possibility of barotrauma or decompression sickness involvement, but does not exclude all other possibilities. The dive profile (which is frequently recorded by dive computer) can be useful to assess a probability for decompression sickness, which can be confirmed by therapeutic recompression.

A stroke (either ischemic or hemorrhagic) involving the posterior fossa is a cause of central vertigo. Risk factors for a stroke as a cause of vertigo include increasing age and known vascular risk factors. Presentation may more often involve headache or neck pain, additionally, those who have had multiple episodes of dizziness in the months leading up to presentation are suggestive of stroke with prodromal TIAs. The HINTS exam as well as imaging studies of the brain (CT, CT angiogram, and/or MRI) are helpful in diagnosis of posterior fossa stroke.

The condition is diagnosed by the patient's history, and by performing the Dix–Hallpike test or the roll test, or both.

The Dix–Hallpike test is a common test performed by examiners to determine whether the posterior semicircular canal is involved. It involves a reorientation of the head to align the posterior semicircular canal (at its entrance to the ampulla) with the direction of gravity. This test will reproduce vertigo and nystagmus characteristic of posterior canal BPPV.

When performing the Dix–Hallpike test, patients are lowered quickly to a supine position, with the neck extended by the clinician performing the maneuver. For some patients, this maneuver may not be indicated, and a modification may be needed that also targets the posterior semicircular canal. Such patients include those who are too anxious about eliciting the uncomfortable symptoms of vertigo, and those who may not have the range of motion necessary to comfortably be in a supine position. The modification involves the patient moving from a seated position to side-lying "without" their head extending off the examination table, such as with Dix–Hallpike. The head is rotated 45 degrees away from the side being tested, and the eyes are examined for nystagmus. A positive test is indicated by patient report of a reproduction of vertigo and clinician observation of nystagmus. Both the Dix–Hallpike and the side-lying testing position have yielded similar results, and as such the side-lying position can be used if the Dix–Hallpike cannot be performed easily.

The roll test can determine whether the horizontal semicircular canal is involved. The roll test requires the patient to be in a supine position with their head in 30° of cervical flexion. Then the examiner quickly rotates the head 90° to the left side, and checks for vertigo and nystagmus. This is followed by gently bringing the head back to the starting position. The examiner then quickly rotates the head 90° to the right side, and checks again for vertigo and nystagmus. In this roll test, the patient may experience vertigo and nystagmus on both sides, but rotating towards the affected side will trigger a more intense vertigo. Similarly, when the head is rotated towards the affected side, the nystagmus will beat towards the ground and be more intense.

As mentioned above, both the Dix–Hallpike and roll test provoke the signs and symptoms in subjects suffering from archetypal BPPV. The signs and symptoms patients with BPPV experience are typically a short-lived vertigo, and observed nystagmus. In some patients, though rarely, the vertigo can persist for years. Assessment of BPPV is best done by a medical health professional skilled in management of dizziness disorders, commonly a physiotherapist, audiologist or other physician.

The nystagmus associated with BPPV has several important characteristics which differentiate it from other types of nystagmus.

- Latency of onset: there is a 5–10 second delay prior to onset of nystagmus.

- Nystagmus lasts for 5–120 seconds.

- Positional: the nystagmus occurs only in certain positions.

- Repeated stimulation, including via Dix–Hallpike maneuvers, cause the nystagmus to fatigue or disappear temporarily.

- Rotatory/Torsional component is present, or (in the case of lateral canal involvement) the nystagmus beats in either a geotropic (towards the ground) or ageotropic (away from the ground) fashion.

- Visual fixation suppresses nystagmus due to BPPV.

Although rare, CNS disorders can sometimes present as BPPV. A practitioner should be aware that if a patient whose symptoms are consistent with BPPV, but does not show improvement or resolution after undergoing different particle repositioning maneuvers — detailed in the Treatment section below — need to have a detailed neurological assessment and imaging performed to help identify the pathological condition.

Vertigo, a distinct process sometimes confused with the broader term, dizziness, accounts for about six million clinic visits in the United States every year; between 17 and 42% of these patients are eventually diagnosed with BPPV.

Other causes of vertigo include:

- Motion sickness/motion intolerance: a disjunction between visual stimulation, vestibular stimulation, and/or proprioception

- Visual exposure to nearby moving objects (examples of optokinetic stimuli include passing cars and falling snow)

- Other diseases: (labyrinthitis, Ménière's disease, and migraine, etc.)

The diagnosis of mastoiditis is clinical—based on the medical history and physical examination. Imaging studies provide additional information; The standard method of diagnosis is via MRI scan although a CT scan is a common alternative as it gives a clearer and more useful image to see how close the damage may have gotten to the brain and facial nerves. Planar (2-D) X-rays are not as useful. If there is drainage, it is often sent for culture, although this will often be negative if the patient has begun taking antibiotics. Exploratory surgery is often used as a last resort method of diagnosis to see the mastoid and surrounding areas.

Patients treated with complete surgical excision can expect an excellent long term outcome without any problems. Recurrences may be seen in tumors which are incompletely excised.

While there is a wide age range at clinical presentation (12–85 years), most patients come to clinical attention at 55 years (mean). There is no gender difference.

Differentiation between this and SCC would be based on a history of recent trauma or dental treatment in the area.

Immunohistochemistry may aid the diagnosis. If the lesion is NS, there will be focal to absent immunoreactivity for p53, low immunoreactivity for MIB1 (Ki-67), and the presence of 4A4/p63- and calponin-positive myoepithelial cells.

Otitis is a general term for inflammation or infection of the ear, in both humans and other animals.

It is subdivided into the following:

- "Otitis externa", external otitis, or "swimmer's ear" involves the outer ear and ear canal. In external otitis, the ear hurts when touched or pulled.

- "Otitis media" or middle ear infection involves the middle ear. In otitis media, the ear is infected or clogged with fluid behind the ear drum, in the normally air-filled middle-ear space. This very common childhood infection sometimes requires a surgical procedure called "myringotomy" and tube insertion.

- "Otitis interna" or labyrinthitis involves the inner ear. The inner ear includes sensory organs for balance and hearing. When the inner ear is inflamed, "vertigo" is a common symptom.

No known treatment for BPT currently exists. However, the condition it is self-limiting and resolves after about eighteen months.

With prompt treatment, it is possible to cure mastoiditis. Seeking medical care early is important. However, it is difficult for antibiotics to penetrate to the interior of the mastoid process and so it may not be easy to cure the infection; it also may recur. Mastoiditis has many possible complications, all connected to the infection spreading to surrounding structures. Hearing loss is likely, or inflammation of the labyrinth of the inner ear (labyrinthitis) may occur, producing vertigo and an ear ringing may develop along with the hearing loss, making it more difficult to communicate. The infection may also spread to the facial nerve (cranial nerve VII), causing facial-nerve palsy, producing weakness or paralysis of some muscles of facial expression, on the same side of the face. Other complications include Bezold's abscess, an abscess (a collection of pus surrounded by inflamed tissue) behind the sternocleidomastoid muscle in the neck, or a subperiosteal abscess, between the periosteum and mastoid bone (resulting in the typical appearance of a protruding ear). Serious complications result if the infection spreads to the brain. These include meningitis (inflammation of the protective membranes surrounding the brain), epidural abscess (abscess between the skull and outer membrane of the brain), dural venous thrombophlebitis (inflammation of the venous structures of the brain), or brain abscess.

Benign paroxysmal torticollis disappears in the early years of life with no medical intervention.

However, some cases of benign paroxysmal torticollis cases can evolve into benign paroxysmal vertigo of childhood, migrainous vertigo or typical migraines.

Diagnosis is based on clinical findings.

'Clinical findings'

- Profound congenital sensorineural deafness is present

- CT scan or MRI of the inner ear shows no recognizable structure in the inner ear.

- As michel's aplasia is associated with LAMM syndrome there will be Microtia and microdontia present(small sized teeth).

Molecular genetic Testing

1. "FGF3" is the only gene, whose mutation can cause congenital deafness with Michel's aplasia, microdontia and microtia

Carrier testing for at-risk relatives requires identification of mutations which are responsible for occurrence of disease in the family.

No treatment is required, but neoplastic processes (metastatic maliganancy to the submandibular lymph nodes and/or salivary gland tumours) should be ruled out. This is usually done with clinical exam and imaging. Very rarely, since the defect contains salivary gland tissue, salivary gland tumors can occur within an established defect but there is likely no difference in the risk of neoplasia in salivary gland tissue at other sites.

Treatment is not needed in the asymptomatic patient. Symptomatic patients may benefit from surgical debulking of the tumor. Complete tumor removal is not usually needed and can be difficult due to the tumor location.

Imaging studies are performed before surgery or biopsy to preclude an intracranial connection. Images usually show a sharply circumscribed but expansile mass. It may be difficult to exclude the intracranial connection if the defect is small whether employing computed tomography or magnetic resonnance.

The most common missed lesion is within the nasal cavity, where a fibrosed nasal polyp may be considered. However, it does not have glial tissue. Further, a polyp usually has mucoserous glands. The lesion is frequently misintrepreted as scar in the subcutaneous tissues, but scar in a <2 year old child would be uncommon. Special stains are frequently required to highlight the diagnosis.

Lhermitte–Duclos disease is a rare entity; approximately 222 cases of LDD have been reported in medical literature. Symptoms of the disease most commonly manifest in the third and fourth decades of life, although it may onset at any age. Men and women are equally affected, and there is not any apparent geographical pattern.

The diagnosis of episcleritis is based upon the history and physical examination. The history should be explored for the presence of the diseases associated with episcleritis, and the symptoms they cause, such as rash, arthritis, venereal disease, and recent viral infection. Episcleritis may be differentiated from scleritis by using phenylephrine or neosynephrine eye drops, which causes blanching of the blood vessels in episcleritis, but not in scleritis. A blue color to the sclera suggests scleritis, rather than episcleritis.

After anesthetizing the eye with medication, the conjunctiva may be moved with a cotton swab to observe the location of the enlarged blood vessels.

Healing is prolonged, and usually takes 6–10 weeks. The ulcer heals by secondary intention.

Stafne defect is uncommon, and has been reported to develop anywhere between the ages of 11 and 30 years old, (although the defect is developmental, it does not seem to be present form birth, implying that the lesion develops at a later age). Usually the defect is unilateral (on one side only) and most commonly occurs in men.

About 20–30% of the population report to have experienced dizziness at some point in the previous year.

Since the majority of ACA cases result from a post-viral infection, the physician’s first question will be to ask if the patient has been recently ill. From this point a series of exclusion tests can determine if the current state of ataxia is a correct diagnosis or not. A CT (computed tomography) scan with normal results can rule out the possibility of the presence of a posterior fossa tumor and an acute hemorrhage, which would both have abnormal results. Other imaging tests like EEG (electroencephalographs) and MRI (magnetic resonance imaging) can also be performed to eliminate possible diagnoses of other severe diseases, such as neuroblastoma, drug intoxication, acute labyrinthitis, and metabolic diseases. A more complicated test that is performed for research analysis of the disease is to isolate viruses from the CSF (cerebrospinal fluid). This can show that the virus has attacked the nervous system of the patient and resulted in the ataxia symptoms.
