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.

- Avoid activity during extremely cold or windy conditions.

- Keep the ear canal as warm and dry as possible.

- Ear plugs

- Wetsuit hood

- Swim cap

- Diving helmet

Because an acute hematoma can lead to cauliflower ear, prompt evacuation of the blood is needed to prevent permanent deformity. The outer ear is prone to infections, so antibiotics are usually prescribed. Pressure is applied by bandaging, helping the skin and the cartilage to reconnect. Without medical intervention the ear can suffer serious damage. Disruption of the ear canal is possible. The outer ear may wrinkle, and can become slightly pale due to reduced blood flow; hence the common term "cauliflower ear". Cosmetic procedures are available that can possibly improve the appearance of the ear.

Headgear called a "scrum cap" in rugby, or simply "headgear" or earguard in wrestling and other martial arts, that protects the ears is worn to help prevent this condition. For some athletes, however, a cauliflower ear is considered a badge of courage or experience.

The majority of patients present in their mid-30s to late 40s. This is likely due to a combination of the slow growth of the bone and the decreased participation in activities associated with surfer's ear past the 30's. However surfer's ear is possible at any age and is directly proportional to the amount of time spent in cold, wet, windy weather without adequate protection.

The normal ear canal is approximately 7mm in diameter and has a volume of approximately 0.8 ml (approximately one-sixth of a teaspoon). As the condition progresses the diameter narrows and can even close completely if untreated, although sufferers generally seek help once the passage has constricted to 0.5-2mm due to the noticeable hearing impairment. While not necessarily harmful in and of itself, constriction of the ear canal from these growths can trap debris, leading to painful and difficult to treat infections.

Prominent ear, otapostasis or bat ear is an abnormally protruding human ear. It may be unilateral or bilateral. The concha is large with poorly developed antihelix and scapha. It is the result of malformation of cartilage during primitive ear development in intrauterine life. The deformity can be corrected anytime after 6 years. The surgery is preferably done at the earliest in order to avoid psychological distress. Correction by otoplasty involves changing the shape of the ear cartilage so that the ear is brought closer to the side of the head. The skin is not removed, but the shape of the cartilage is altered. The surgery does not affect hearing. It is done for cosmetic purposes only. The complications of the surgery, though rare, are keloid formation, hematoma formation, infection and asymmetry between the ears.

Myringosclerosis seems to be more common than tympanosclerosis. Most research has not been conducted upon the general, healthy population, but rather those with otitis media or patients who have had tympanostomy tubes in prior procedures. Of the children studied who had 'glue ear', and who were treated with tympanostomy tubing, 23-40% of cases had tympanosclerosis. One study suggested that people with atherosclerosis were more likely to have tympanosclerosis than otherwise healthy individuals.

Cryptotia is often treated through surgery which involves releasing the ear from its buried position, reshaping the cartilage and using local tissue to resurface the released cartilage.

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.

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.

When diagnosing, PLF should be differentiated from Ménière's disease. Tympanostomy has been reported to be a way to diagnose and cure PLF.

Cryptotia is the condition where an ear appears to have its upper portion buried underneath the side of the head. The condition also involves underdeveloped scapha and antihelical crura. Cryptotia is also known as buried ear or hidden ear.

Various strategies may be used to manage tympanic membrane retraction, with the aims of preventing or relieving hearing loss and cholesteatoma formation.

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.

Courses of treatment typically include the following:

- Draining the pus once awhile as it can build up a strong odor

- Antibiotics when infection occurs.

- Surgical excision is indicated with recurrent fistular infections, preferably after significant healing of the infection. In case of a persistent infection, infection drainage is performed during the excision operation. The operation is generally performed by an appropriately trained specialist surgeon e.g. an otolaryngologist or a specialist General Surgeon.

- The fistula can be excised as a cosmetic operation even though no infection appeared. The procedure is considered an elective operation in the absence of any associated complications.

As retraction pockets may remain stable or resolve spontaneously, it may be appropriate to observe them for a period of time before considering any active treatment.

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.

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.

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.

This can be done by annual evaluations by multidiciplinary team involving otolaryngologist, clinical geneticist, a pediatrician, the expertise of an educator of the deaf, a neurologist is appropriate.

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.

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.

The strategies for preventing acute external otitis are similar to those for treatment.

- Avoid inserting "anything" into the ear canal: use of cotton buds or swabs is the most common event leading to acute otitis externa.

- Most normal ear canals have a self-cleaning and self-drying mechanism, the latter by simple evaporation.

- After prolonged swimming, a person prone to external otitis can dry the ears using a small battery-powered ear dryer, available at many retailers, especially shops catering to watersports enthusiasts. Alternatively, drops containing dilute acetic acid (vinegar diluted 3:1) or Burow's solution may be used. It is especially important NOT to instrument ears when the skin is saturated with water, as it is very susceptible to injury, which can lead to external otitis.

- Avoid swimming in polluted water.

- Avoid washing hair or swimming if very mild symptoms of acute external otitis begin

- Although the use of earplugs when swimming and shampooing hair may help prevent external otitis, there are important details in the use of plugs. Hard and poorly fitting ear plugs can scratch the ear canal skin and set off an episode. When earplugs are used during an acute episode, either disposable plugs are recommended, or used plugs must be cleaned and dried properly to avoid contaminating the healing ear canal with infected discharge.

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.

Presence of inner ear abnormalities lead to Delayed gross development of child because of balance impairment and profound deafness which increases the risk of trauma and accidents.

- Incidence of accidents can be decreased by using visual or vibrotactile alarm systems in homes as well as in schools.

- Anticipatory education of parents, health providers and educational programs about hazards can help.

Otosclerosis or otospongiosis is an abnormal growth of bone near the middle ear. It can result in hearing loss. The term otosclerosis is something of a misnomer. Much of the clinical course is characterised by lucent rather than sclerotic bony changes, hence it is also known as otospongiosis.
