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.
"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 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.
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.
These are intended to improve Eustachian tube function. Adenoidectomy can improve middle ear function and nasal steroid sprays can reduce adenoid size but it is not known whether these treatments alter tympanic membrane retraction.
There is no cure for Ménière's disease but medications, diet, physical therapy and counseling, and some surgical approaches can be used to manage it.
During MD episodes, medications to reduce nausea are used, as are drugs to reduce the anxiety caused by vertigo.
For longer term treatment to stop progression, the evidence base is weak for all treatments.
Although a causal relation between allergy and Menière's disease is uncertain, medication to control allergies may be helpful.
Diuretics are widely used to manage Ménière's on the theory that it reduces fluid buildup in the ear. Based on evidence from multiple but small clinical trials, diuretics appear to be useful for reducing the frequency of episodes of dizziness, but do not seem to prevent hearing loss.
In cases where there is significant hearing loss and continuing severe episodes of vertigo, a chemical labyrinthectomy, in which a drug (such as gentamicin) that "kills" parts or most of the vestibular apparatus is injected into the middle ear.
Enlargement of the Eustachian tube opening in the nose with laser or balloon dilatation is being evaluated as a potential treatment for tympanic membrane retraction.
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.
Definitive treatment depends on the underlying cause of vertigo. Ménière's disease patients have a variety of treatment options to consider when receiving treatment for vertigo and tinnitus including: a low-salt diet and intratympanic injections of the antibiotic gentamicin or surgical measures such as a shunt or ablation of the labyrinth in refractory cases.
Common drug treatment options for vertigo may include the following:
- Anticholinergics such as hyoscine hydrobromide (scopolamine)
- Anticonvulsants such as topiramate or valproic acid for vestibular migraines
- Antihistamines such as betahistine, dimenhydrinate, or meclizine, which may have antiemetic properties
- Beta blockers such as metoprolol for vestibular migraine
- Corticosteroids such as methylprednisolone for inflammatory conditions such as vestibular neuritis or dexamethasone as a second-line agent for Ménière's disease
All cases of decompression sickness should be treated initially with 100% oxygen until hyperbaric oxygen therapy (100% oxygen delivered in a high-pressure chamber) can be provided. Several treatments may be necessary, and treatment will generally be repeated until either all symptoms resolve, or no further improvement is apparent.
About half of people with SSNHL will recover some or all of their hearing spontaneously, usually within one to two weeks from onset. Eighty-five percent of those who receive treatment from an otolaryngologist (sometimes called an ENT) will recover some of their hearing.
- vitamins and antioxidants
- vasodilators
- betahistine (Betaserc), an anti-vertigo drug
- hyperbaric oxygen
- anti-inflammatory agents, primarily oral corticosteroids such as prednisone, methylprednisone
- Intratympanic administration - Gel formulations are under investigation to provide more consistent drug delivery to the inner ear. Local drug delivery can be accomplished through intratympanic administration, a minimally invasive procedure where the ear drum is anesthetized and a drug is administered into the middle ear. From the middle ear, a drug can diffuse across the round window membrane into the inner ear. Intratympanic administration of steroids may be effective for sudden sensorineural hearing loss for some patients, but high quality clinical data has not been generated. Intratympanic administration of an anti-apoptotic peptide (JNK inhibitor) is currently being evaluated in late-stage clinical development.
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.
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.
Treatment modalities fall into three categories: pharmacological, surgical, and management. As SNHL is a physiologic degradation and considered permanent, there are as of this time, no approved or recommended treatments.
There have been significant advances in identification of human deafness genes and elucidation of their cellular mechanisms as well as their physiological function in mice. Nevertheless, pharmacological treatment options are very limited and clinically unproven. Such pharmaceutical treatments as are employed are palliative rather than curative, and addressed to the underlying cause if one can be identified, in order to avert progressive damage.
Profound or total hearing loss may be amenable to management by cochlear implants, which stimulate cochlear nerve endings directly. A cochlear implant is surgical implantation of a battery powered electronic medical device in the inner ear. Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain. These consist of both internal implanted electrodes and magnets and external components. The quality of sound is different than natural hearing but may enable the recipient to better recognize speech and environmental sounds.
Because of risk and expense, such surgery is reserved for cases of severe and disabling hearing impairment
Management of sensorineural hearing loss involves employing strategies to support existing hearing such as lip-reading, enhanced communication etc. and amplification using hearing aids. Hearing aids are specifically tuned to the individual hearing loss to give maximum benefit.
Treatment is supportive and consists of management of manifestations. User of hearing aids and/or cochlear implant, suitable educational programs can be offered. Periodic surveillance is also important.
At present, presbycusis, being primarily sensorineural in nature, cannot be prevented, ameliorated or cured. Treatment options fall into three categories: pharmacological, surgical and management.
- There are no approved or recommended pharmaceutical treatments for presbycusis.
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.
These are surgically implanted hearing aids inserted onto the middle ear. These aids work by directly vibrating the ossicles, and are cosmetically favorable due to their hidden nature.
Historically, to temporarily alleviate symptoms, patients have tried positional maneuvers, such as tilting their head to one side or upside down, lie down on their backs, or sit in a chair with their head between their knees. Similarly, a routine of lying down four times per day with legs elevated to around 20 inches for at least two weeks has been attempted as well. Depending on the underlying cause of the disorder, the individual may need to remove caffeine from their diet, reduce exercise, or gain weight. It may be the case that the symptoms are induced by anxiety; anxiolytic drugs or supplements (e.g., GABA) combined with the removal of caffeine from the diet could offer a simple strategy to determine if anxiety is the root cause.
Estrogen (Premarin) nasal drops or saturated potassium iodide have been used to induce edema of the eustachian tube opening. Nasal medications containing diluted hydrochloric acid, chlorobutanol, and benzyl alcohol have been reported to be effective in some patients, with few side effects. Food and Drug Administration approval is still pending, however.
In extreme cases surgical intervention may attempt to restore the Eustachian tube tissues with fat, gel foam, or cartilage or scar it closed with cautery. These methods are not always successful.
Oral and topical pain killers are effective to treat the pain caused by otitis media. Oral agents include ibuprofen, paracetamol (acetaminophen), and opiates. Topical agents shown to be effective include antipyrine and benzocaine ear drops. Decongestants and antihistamines, either nasal or oral, are not recommended due to the lack of benefit and concerns regarding side effects. Half of cases of ear pain in children resolve without treatment in three days and 90% resolve in seven or eight days. The use of steroids is not supported by the evidence for acute otitis media.
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.
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.
Tympanostomy tubes (also called "grommets") are recommended with three or more episodes of acute otitis media in 6 months or four or more in a year, with at least one episode or more attacks in the preceding 6 months. There is tentative evidence of reduced recurrence rates in the 6 months after placement. Evidence does not support an effect on long-term hearing or language development. A common complication of having a tympanostomy tube is otorrhea, which is a discharge from the ear.
Oral antibiotics should not be used to treat uncomplicated acute tympanostomy tube otorrhea. Oral antibiotics are not a sufficient response to bacteria that cause this condition and have significant side effects including increased risk of opportunistic infection. In contrast, topical antibiotic eardrops can treat this condition.
It is normally possible to establish the cause of ear pain based on the history. It is important to exclude cancer where appropriate, particularly with unilateral otalgia in an adult who uses tobacco or alcohol.Often migraines are caused by middle ear infections which can easily be treated with antibiotics. Often using a hot washcloth can temporarily relieve ear pain.
