Patients are advised to treat with bed rest and avoiding activities that increase intracranial pressure (i.e. weightlifting, valsalva, scuba diving, flying in airplanes) with the hopes of the membrane healing on their own. Appropriate Physical therapy / vestibular rehabilitation techniques can be helpful in managing symptoms of movement sensitivity.
Cholesteatoma is a persistent disease. Once the diagnosis of cholesteatoma is made in a patient who can tolerate a general anesthetic, the standard treatment is to surgically remove the growth.
The challenge of cholesteatoma surgery is to permanently remove the cholesteatoma whilst retaining or reconstructing the normal functions of the structures housed within the temporal bone.
The general objective of cholesteatoma surgery has two parts. It is both directed against the underlying pathology and directed towards maintaining the normal functions of the temporal bone. These aims are conflicting and this makes cholesteatoma surgery extremely challenging.
Sometimes, the situation results in a clash of surgical aims. The need to fully remove a progressive disease like cholesteatoma is the surgeon's first priority. Preservation of hearing is secondary to this primary aim. If the disease can be removed easily so that there is no increased risk of residual disease, then the ossicles may be preserved. If the disease is difficult to remove, so that there is an increased risk of residual disease, then removal of involved ossicles in order to fully clear cholesteatoma has generally been regarded as necessary and reasonable.
In other words, the aims of cholesteatoma treatment form a hierarchy. The paramount objective is the complete removal of cholesteatoma. The remaining objectives, such as hearing preservation, are subordinate to the need for complete removal of cholesteatoma. This hierarchy of aims has led to the development of a wide range of strategies for the treatment of cholesteatoma.
Surgery to remove the obstructing ear canal bone is usually performed under general anesthesia in an operating room and aided by the use of a binocular microscope. Most ear surgeons use a drill to remove the bone and may approach the area directly via the ear canal or by making an incision behind the ear and dissecting the ear forward. In using a drilling technique it is important to keep the thin inner ear canal skin away from the drill to preserve the skin and allow optimal skin coverage at the conclusion of the surgery.
Some doctors now prefer to use 1 millimeter chisels to remove the obstructing bone and enter directly through the ear canal. This technique enhances skin preservation. This technique may, in some cases, be performed under sedation with local anesthesia.
During recuperation from surgery it is extremely important not to expose the ear canal to water to minimize the chance of infection or complications.
Depending on the condition of the ear canal and the surgical technique used, the ear canal may require several weeks to several months to heal.
Unprotected exposure of ear canals to cold water and wind after treatment can lead to regrowth of bone and the need for repeated operations on the same ear.
Medical treatment with anti-vertigo medications may be considered in acute, severe exacerbation of BPPV, but in most cases are not indicated. These primarily include drugs of the anti-histamine and anti-cholinergic class, such as meclizine and hyoscine butylbromide (scopolamine) respectively. The medical management of vestibular syndromes has become increasingly popular over the last decade, and numerous novel drug therapies (including existing drugs with new indications) have emerged for the treatment of vertigo/dizziness syndromes. These drugs vary considerably in their mechanisms of action, with many of them being receptor- or ion channel-specific. Among them are betahistine or dexamethasone/gentamicin for the treatment of Ménière's disease, carbamazepine/oxcarbazepine for the treatment of paroxysmal dysarthria and ataxia in multiple sclerosis, metoprolol/topiramate or valproic acid/tricyclic antidepressant for the treatment of vestibular migraine, and 4-aminopyridine for the treatment of episodic ataxia type 2 and both downbeat and upbeat nystagmus. These drug therapies offer symptomatic treatment, and do not affect the disease process or resolution rate. Medications may be used to suppress symptoms during the positioning maneuvers if the patient's symptoms are severe and intolerable. More dose-specific studies are required, however, in order to determine the most effective drug(s) for both acute symptom relief and long-term remission of the condition.
Surgical treatments, such as a semi-circular canal occlusion, do exist for BPPV, but carry the same risk as any neurosurgical procedure. Surgery is reserved as a last resort option for severe and persistent cases which fail vestibular rehabilitation (including particle repositioning and habituation therapy).
The variation in technique in cholesteatoma surgery results from each surgeon's judgment whether to retain or remove certain structures housed within the temporal bone in order to facilitate the removal of cholesteatoma. This typically involves some form of mastoidectomy which may or may not involve removing the posterior ear canal wall and the ossicles.
Removal of the canal wall facilitates the complete clearance of cholesteatoma from the temporal bone in three ways:
1. it removes a large surface onto which cholesteatoma may be adherent;
2. it removes a barrier behind which the cholesteatoma may be hidden;
3. it removes an impediment to the introduction of instruments used for the removal of cholesteatoma.
Thus removal of the canal wall provides one of the most effective strategies for achieving the primary aim of cholesteatoma surgery, the complete removal of cholesteatoma. However, there is a trade-off, since the functional impact of canal wall removal is also important.
The removal of the ear canal wall results in:
- a space, the "mastoid cavity", which is less likely than the original ear canal to resist infection;
- exposure of the ossicles, which may allow the subsequent formation of a new cholesteatoma deep to the ossicles. To prevent this, these ossicles must be removed, which may diminish the patient's hearing.
The formation of a mastoid cavity by removal of the canal wall is the simplest and most effective procedure for facilitating the removal of cholesteatoma, but may bestow the most lasting infirmity due to loss of ear function upon the patient treated in this way.
The following strategies are employed to mitigate the effects of canal wall removal:
1. careful design and construction of the mastoid cavity. This is essential for the health and integrity of the protective sheet of migrating, keratising epithelium which lines the distorted ear canal. This requires the surgeon to saucerise the cavity. A high facial ridge and an inappropriately small cartilaginous meatus are obstructions to epithelial migration and are particularly high risk factors for failure of the self-cleaning mechanism of the external ear.
2. partial obliteration of the mastoid cavity. This can be performed using a wide range of materials. Many of these resorb in time, which means that the long-term results of such surgery are poorer than the short-term results.
3. reconstruction of the ear canal wall. Canal wall reconstruction has been performed using ear canal skin alone, fascia, cartilage, titanium as well as by replacing the original intact wall. If the reconstruction is poorly performed, it may result in a high rate of recurrent cholesteatoma.
4. preservation of the ear canal wall. If poorly performed, it may result in a high rate of both residual and recurrent cholesteatoma.
5. reconstruction of the chain of hearing bones.
Clearly, preservation and restoration of ear function at the same time as total removal of cholesteatoma requires a high level of surgical expertise.
Hearing aids are a common treatment for hearing loss disorders. A more specific treatment is surgical, involving excision of the sclerotic areas and then further repair of the ossicular chain. There are several techniques, sometimes involving two surgeries; success rates are, however, variable. Damage to the inner ear as a result of surgical procedures is a possible and serious concern, as it can result in forms of sensorineural deafness.
The objective of irradiation is to halt the growth of the acoustic neuroma tumour, it does not excise it from the body, as the term 'radiosurgery' or 'gammaknife' implies. Radiosurgery is only suitable for small to medum size tumors.
There are three modalities of surgical treatment (excision) depending on where the anatomical location of the incision to access the tumor is made: retrosigmoid (a variant of what was formerly called suboccipital), translabyrinthine, and middle fossa.
The goals of surgery are to control the tumor, and preserve hearing as well as facial nerves. Especially in the case of larger tumors, there may be a tradeoff between tumor removal and preservation of nerve functionality.
There are different defined degrees of surgical excision, termed 'subtotal resection', 'radical subtotal resection', 'near-total resection', and 'total resection' in order or increasing proportion of tumor removed. Lesser amount of tumor removal may increase likelihood of preservation of nerve function (hence better post-operative hearing), but also likelihood of tumor regrowth, necessitating additional treatment.
Earlier workers suggested the use of calcium fluoride; now sodium fluoride is the preferred compound. Fluoride ions inhibit the rapid progression of disease. In the otosclerotic ear, there occurs formation of hydroxylapatite crystals which lead to stapes (or other) fixation. The administration of fluoride replaces the hydroxyl radical with fluoride leading to the formation of fluorapatite crystals. Hence, the progression of disease is considerably slowed down and active disease process is arrested.
This treatment cannot reverse conductive hearing loss, but may slow the progression of both the conductive and sensorineural components of the disease process. Otofluor, containing sodium fluoride, is one treatment. Recently, some success has been claimed with a second such treatment, bisphosphonate medications that inhibit bone destruction. However, these early reports are based on non-randomized case studies that do not meet standards of clinical trials. There are numerous side-effects to both pharmaceutical treatments, including occasional stomach upset, allergic itching, and increased joint pains which can lead to arthritis. In the worst case, bisphosphonates may lead to osteonecrosis of the auditory canal itself. Finally, neither approach has been proven to be beneficial after the commonly preferred method of surgery has been undertaken.
Once diagnosed, the gap in the temporal bone can be repaired by surgical resurfacing of the affected bone or plugging of the superior semicircular canal. These techniques are performed by accessing the site of the dehiscence either via a middle fossa craniotomy or via a canal drilled through the transmastoid bone behind the affected ear. Bone cement has been the material most often used, in spite of its tendency to slippage and resorption, and a consequent high failure rate; recently, soft tissue grafts have been substituted.
The widespread use of wetsuits has allowed people to surf in much colder waters, which has increased the incidence and severity of surfer's ear for people who do not properly protect their ears.

There is no treatment to correct an enlarged vestibular aqueduct. Any hearing loss will need management with amplification and support in education and at work. If the hearing loss becomes severe to profound cochlear implants can be of significant value. Vestibular disturbance is usually short-lived and associated with head trauma but significant vestibular hypofunction may require rehabilitation.
People with enlarged vestibular aqueducts are advised to avoid head trauma where possible. This usually means avoiding contact sports such as boxing and rugby, but also horse riding, trampolining and other sports where head injury may occur. Some have symptoms when flying and should limit these activities if affected.
Vestibular neuronitis is generally a self-limiting disease. Treatment with drugs is neither necessary nor possible. The effect of glucocorticoids has been studied, but they have not been found to significantly affect long-term outcome.
Symptomatic treatment with antihistaminics such as cinnarizine, however, can be used to suppress the symptoms of vestibular neuronitis while it spontaneously regresses. Prochlorperazine is another commonly prescribed medication to help alleviate the symptoms of vertigo and nausea.
Studies have shown that older adults with dementia who take antipsychotics (medications for mental illness) such as prochlorperazine have an increased chance of death during treatment.
Treatment differs depending on the cause. Each cause has a different treatment, and may involve either medical treatment, surgery, or therapy. If serious damage has already been done, then the focus of treatment is upon avoidance of vestibular suppressants and ototoxins. It is recommended that you tell your physicians to avoid drugs that end in mycin ( Azithromycin, Erythromycin ) because of possible reactions which could lead to setbacks. Vestibular rehabilitation is important. Your physician will try to keep the administering of drugs to a minimum.
Because mood disorders can interfere with the vestibular compensation and adaptive plasticity, it suggested to address any co-occurring anxiety disorder and/or depression. Severe anxiety episodes are usually addressed by short-term benzodiazapine therapy. Long-term use of benzodiazapines such as diazepam, however, is not recommended due to the tolerance issues. SSRIs and SSNRIs are among a number of first line treatments for anxiety or depression.
The treatment will vary with the different grades, but the most common is a surgical repair. The surgical option is cosmetic reconstruction of the external ear's normal shape and repair of the ear canal. In less severe cases the reconstruction will be sufficient to restore hearing. In grades of anotia/microtia that affect the middle ear the surgery with the use of a Bone Anchored Hearing Aid (BAHA) will likely restore the hearing. The BAHA may be surgically implanted onto the skull which would allow for some hearing repair by conduction through the skull bone. "This allows sound vibrations to travel through bones in the head to the inner ear."
BAHA: An implantable hearing device. It is the only hearing aid device that works via direct bone conduction.
Sedative drugs are often prescribed for vertigo and dizziness, but these usually treat the symptoms rather than the underlying cause. Lorazepam (Ativan) is often used and is a sedative which has no effect on the disease process, but rather helps patients cope with the sensation.
Anti-nauseants, like those prescribed for motion sickness, are also often prescribed but do not affect the prognosis of the disorder.
Specifically for Meniere's disease a medication called Serc (Beta-histine) is available. There is some evidence to support its effectiveness in reducing the frequency of attacks. Also Diuretics, like Diazide (HCTZ/triamterene), are effective in many patients. Finally, ototoxic medications delivered either systemically or through the eardrum can eliminate the vertigo associated with Meniere's in many cases, although there is about a 10% risk of further hearing loss when using ototoxic medications.
Treatment is specific for underlying disorder of balance disorder:
- anticholinergics
- antihistamines
- benzodiazepines
- calcium channel antagonists, specifically Verapamil and Nimodipine
- GABA modulators, specifically gabapentin and baclofen
- Neurotransmitter reuptake inhibitors such as SSRIs, SNRIs and Tricyclics
Management falls into three modalities: surgical treatment, pharmaceutical treatment, and supportive, depending on the nature and location of the specific cause.
In cases of infection, antibiotics or antifungal medications are an option. Some conditions are amenable to surgical intervention such as middle ear fluid, cholesteatoma, otosclerosis. If conductive hearing loss is due to head trauma, surgical repair is an option. If absence or deformation of ear structures cannot be corrected, or if the patient declines surgery, hearing aids which amplify sounds are a possible treatment option. Bone conduction hearing aids are useful as these deliver sound directly, through bone, to the cochlea or organ of hearing bypassing the pathology. These can be on a soft or hard headband or can be inserted surgically, a bone anchored hearing aid, of which there are several types. Conventional air conduction hearing aids can also be used.
there were no medications effective for tinnitus. There is not enough evidence to determine if antidepressants or acamprosate are useful. While there is tentative evidence for benzodiazepines, it is insufficient to support usage. Anticonvulsants have not been found to be useful. Steroid injections into the middle ear also do not seem to be effective.
Botulinum toxin injection has been tried with some success in some of the rare cases of objective tinnitus from a palatal tremor.
"Ginkgo biloba" does not appear to be effective. The American Academy of Otolaryngology recommends against taking melatonin or zinc supplements to relieve symptoms of tinnitus. In addition, a 2016 Cochrane Review concluded that evidence is not sufficient to support taking zinc supplements to reduce symptoms associated with tinnitus.
There are various methods to treat otosclerosis. However the method of choice is a procedure known as Stapedectomy.
Early attempts at hearing restoration via the simple freeing the stapes from its sclerotic attachments to the oval window were met with temporary improvement in hearing, but the conductive hearing loss would almost always recur. A stapedectomy consists of removing a portion of the sclerotic stapes footplate and replacing it with an implant that is secured to the incus. This procedure restores continuity of ossicular movement and allows transmission of sound waves from the eardrum to the inner ear.
A modern variant of this surgery called a stapedotomy, is performed by drilling a small hole in the stapes footplate with a micro-drill or a laser, and the insertion of a piston-like prothesis. The success rate of either surgery depends greatly on the skill and the familiarity with the procedure of the surgeon. However, comparisons have shown stapedotomy to yield results at least as good as stapedectomy, with fewer complications, and thus stapedotomy is preferred under normal circumstances.
Dysequilibrium arising from bilateral loss of vestibular function – such as can occur from ototoxic drugs such as gentamicin – can also be treated with balance retraining exercises (vestibular rehabilitation) although the improvement is not likely to be full recovery.
The age when outer ear surgery can be attempted depends upon the technique chosen. The earliest is 7 for Rib Cartilage Grafts. However, some surgeons recommend waiting until a later age, such as 8–10 when the ear is closer to adult size. External ear prostheses have been made for children as young as 5.
For auricular reconstruction, there are several different options:
1. "Rib Cartilage Graft Reconstruction:" This surgery may be performed by specialists in the technique. It involves sculpting the patient's own rib cartilage into the form of an ear. Because the cartilage is the patient's own living tissue, the reconstructed ear continues to grow as the child does. In order to be sure that the rib cage is large enough to provide the necessary donor tissue, some surgeons wait until the patient is 8 years of age; however, some surgeons with more experience with this technique may begin the surgery on a child aged six. The major advantage of this surgery is that the patient's own tissue is used for the reconstruction. This surgery varies from two to four stages depending on the surgeon's preferred method. A novel one stage ear reconstruction technique is performed by a few select surgeons. One team is able to reconstruct the entire external ear and ear canal in one operation.
2. "Reconstruct the ear using a polyethylene plastic implant (also called Medpor):" This is a 1–2 stage surgery that can start at age 3 and can be done as an outpatient without hospitalization. Using the porous framework, which allows the patient's tissue to grow into the material and the patient's own tissue flap, a new ear is constructed in a single surgery. A small second surgery is performed in 3–6 months if needed for minor adjustments. This surgery should only be performed by experts in the techniques involved. The use of porous polyethylene implants for ear reconstruction was initiated in the 1980s by Alexander Berghaus.
3. "Ear Prosthesis:" An auricular (ear) prosthesis is custom made by an anaplastologist to mirror the other ear. Prosthetic ears can appear very realistic. They require a few minutes of daily care. They are typically made of silicone, which is colored to match the surrounding skin and can be attached using either adhesive or with titanium screws inserted into the skull to which the prosthetic is attached with a magnetic or bar/clip type system. These screws are the same as the BAHA (bone anchored hearing aid) screws and can be placed simultaneously. The biggest advantage over any surgery is having a prosthetic ear that allows the affected ear to appear as normal as possible to the natural ear. The biggest disadvantage is the daily care involved and knowing that the prosthesis is not real.
Management of ear pain depends on the underlying cause.Most cases of otitis media are self-limiting, resolving spontaneously without treatment within 3–5 days. Age-appropriate analgesics or a warm washcloth placed over the affected ear can help relieve pain until the infection has passed.In some cases ear pain has been treated successfully with manual therapy.
