Dogs that have long-standing ear infections may develop an irreversible disease of the ear canal. Due to chronic inflammation, the ear canal becomes very thickened and can turn into bone. As a result, the infection will not resolve with medications.
Full Answer
The anterior (cranial) canal of one ear is roughly parallel to the posterior canal of the opposite ear of the dog. Again, the lateral canal of each side occupies a nearly horizontal plane. The longest semicircular canal of the dog inner ear is an anterior canal.
So, you may jump to the dog ear cartilage anatomy to know details about them. The auricle or pinna is the externally visible part of the external ear of a dog. It is roughly an elongated funnel-shaped structure with two surfaces, two borders, a base, and an apex. But the shape of the auricle or pinna of the dog varies with the breed.
The outer and middle parts of the canine ear are specific for selection, collection and maintaining pitch of all sound waves which enters the ear. The pictures in this section are reprinted with permission by the copyright owner, Hill's Pet Nutrition, from the Atlas of Veterinary Clinical Anatomy.
Collectively, Dog ear symptoms such as a foul ear smell, head shaking, redness, dog ear scratching, lesions, inflammation, alopecia around the margins of the ear flaps (dog ear hair loss), ear discharge, partial or complete canine deafness and itching are some common symptoms related to ear canal problems.
Otosclerosis can't be cured. Surgery can greatly improve the hearing loss caused by otosclerosis. Hearing aids can successfully manage your hearing loss as well.
Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter.
Otosclerosis is a rare condition that causes hearing loss. It happens when a small bone in your middle ear -- usually the one called the stapes -- gets stuck in place. Most of the time, this happens when bone tissue in your middle ear grows around the stapes in a way it shouldn't.
Surgery -- Surgery can be a highly effective treatment for otosclerosis. The procedure is called a "stapedectomy" (or "stapedotomy"). The procedure is intended to "bypass" the fixed part of the stapes bone by removing it, and replacing it with a new, mobile, prosthetic bone.
Through a surgery called stapedectomy, a surgeon removes all or part of the original stapes bone and replaces it with an artificial device. The result allows sound waves to be sent once again to the inner ear for hearing. The surgeon performs the procedure through the ear canal and uses an operating microscope.
Unfortunately, bone spurs don't go away on their own. If addressed quickly with a podiatrist, your bone spurs can be treated using non-invasive methods. Some of those methods include: Daily stretching and low-impact exercises.
Mastoiditis can be cured if treated with antibiotics right away. It may come back periodically (recur) in some individuals. If infection spreads, serious complication can arise including hearing loss, bone infection, blood clots, brain abscess, and meningitis.
When otosclerosis spreads to the inner ear a sensorineural hearing impairment may result due to interference with the nerve function. This nerve impairment is called cochlear otosclerosis and one it develops it may be permanent.
Otosclerosis is diagnosed using tests including:hearing tests – a person with otosclerosis typically has a hearing loss that affects all frequencies (pitches). The hearing loss may be conductive or mixed in nature. ... CT scan – to check for damage to the cochlear nerve and labyrinth.
Stapedectomy is successful in restoring hearing in more than 90 percent of cases, and the gain in hearing is usually permanent. In a small number of cases, there is no improvement in hearing.
Total ear canal ablation (TECA) is a common surgical procedure that is often used as a last resort when all other measures were tried and the dog's ear has sustained irreversible damage. The procedure is often referred to as a " salvage procedure " meaning that its aim is to provide relief when there is no more hope of a medical solution.
Other complications may include trouble chewing or pain opening the mouth, Horner's syndrome, balance problems (head tilt and staggering) swelling and recurrent infections. The dog's sense of hearing may also decrease following surgery, but most dogs had already hearing loss prior to surgery due to thickened ear canal.
This additional procedure which entail removal of infected tissue, is called a "b ulla osteotomy" and it's often included with ...
Many dogs keep their mouths open when playing and dog owners may wonder all about this doggy facial expression and what it denotes. In order to better understand this particular behavior, it helps taking a closer look into how dogs communicate with each other and the underlying function of the behavior.
The costs for dog ablation surgery may vary from place to place, but as a rough estimate, you can expect to pay anywhere between $1200 and $4000.
Fortunately though, in most cases the paralysis is temporary and subsides within 2 weeks , explains Dr. Degner.
What dogs generally need total ear canal ablation? Dogs who have suffered from chronic ear infections sustain significant damage to their ears over time. The long-standing inflammation causes the ear canal to considerably thicken, up to the point of turning into bone, and at that point, treatment will no longer work, explains board-certified veterinary surgeon Dr. Daniel A. Degner.
The pinna is shaped to capture sound waves and funnel them through the ear canal to the eardrum. In dogs, the pinnae are mobile and can move independently of each other. The size and shape of the pinnae vary by breed. The ear canal of the dog is much deeper than that of people and creates a better funnel to carry sound to the eardrum.
He or she will then use an instrument called an otoscope to view the ear canal and eardrum.
The middle ear includes the eardrum and a small, air-filled chamber that contains 3 tiny bones: the hammer, anvil, and stirrup. It also includes 2 muscles, the oval window, and the eustachian tube (a small tube that connects the middle ear with the back of the nose, allowing air to enter the middle ear). The inner ear is a complex structure that ...
In some cases, hair may need to be removed from the ear canals to allow the veterinarian a clear view of the eardrum. If an infection is suspected, tests will be performed on samples of fluid or secretions from the ear to determine the organisms involved and the proper treatment.
Ear Structure and Function in Dogs. The ear is an organ of hearing and an organ of balance. It consists of the outer, middle, and inner ear. The outer ear includes the pinna (the part you see that is made of cartilage and covered by skin, fur, or hair) and the ear canal. The pinna is shaped to capture sound waves and funnel them through ...
The inner ear is a complex structure that includes the cochlea (the organ of hearing) and the vestibular system (the organ of balance).

The bulla is a bony “bubble” at the bottom of the ear canal. At this stage of the disease, it routinely contains pus, which needs to be removed to reach good results. A sterile swab, called a culture, will also reveal which bacteria lives there, and which antibiotic will take care of it.
AJ Debiasse, a technician in Stroudsburg, PA, contributed to this article. Hershey, a 6 year old cocker spaniel, had been in and out of the vet for ear infections for almost all of his life. He had been treated with just about every oral antibiotic, and every type of ear medication known to man.
He also had to rest strictly for 3 weeks to protect the surgery site from any addition trauma. After 3 weeks , the incision looked great and surgery was then scheduled for the second ear. After another 3 weeks of rest, Hershey was allowed to resume his normal activity.
An instrument (called an otoscope) would not even fit inside the ear canals because they had become so narrow. Years of ear infections had transformed the soft and delicate cartilage of the ear canals into a hard, painful, infected mess.
A TECA is a challenging procedure which, like any surgery, presents some risks. The most common complication of a TECA is called facial nerve paralysis. The facial nerve is connected to multiple muscles of the face. If that nerve is damaged during surgery, the patient will lose function of several of those muscles.
If that nerve is damaged during surgery, the patient will lose function of several of those muscles. The most significant consequence is the inability to blink. This causes dry eye, since the tears are no longer able to spread over the entire eye. When this happens, artificial tears need to be applied to the eye.
Hershey’s guardians asked if there were less invasive options. “Other surgeries do exist, but they will fail in Hershey’s case. Only a TECA will take care of the entire problem. And only a TECA allows cleaning up the bulla.”. Understanding TECA to treat Hershey’s ear infection.
Once the ear canal is exposed to foreign allergens , microbes, stress or if it is not lubricated with an adequate amount of ear wax, different dog ear problems may develop. Similarly, if the immune system of the dog is suppressed or if the dog is experiencing any generalized illness, there is a chance that this will lead to increased microbial ...
Treatment and Prevention Ear Canal Problems: In order to treat any problem in the ear canal, specific drugs such as antibiotics, anti fun gal drugs, anti parasitic, insecticides and some types of steroids are used; all of which should only be used with a prescription.
The canine ear canal contains populations of microorganisms, including parasites, bacteria, fungus and some allergens. These agents grow in limited populations, with growth controlled by the dog ear wax. Once the ear canal is exposed to foreign allergens, microbes, stress or if it is not lubricated with an adequate amount of ear wax, ...
The middle ear ends with up to three different layers, which are collectively called ear drums. When sound waves hit these layers and the inner ear, which is the major functional part of a dog’s ear, the brain assesses and coordinates the identification of the sound wave.
A dog’s ear mainly has three parts, which appears as a canal. These are the external, middle and internal parts, which are distributed with different anatomical features. The outer and middle parts of the canine ear are specific for selection, collection and maintaining pitch of all sound waves which enters the ear. Dog Ear Diagram.
Moreover, associated anatomical bodies such as cartilages, nerves, vascular supply, glands and the ear cavity assists in the normal functioning of ear, and helps the body to maintain balance.
When it comes to ear problems, dog owners can only examine or clean the outer part of the ear canal, The middle and inner part of ear can only be examined with the help of an instrument called an otoscope and other related equipment, which can only be found in a veterinarians office.
As a veterinary student or pet dog practitioner, you might have a good piece of knowledge on dog ear anatomy. You may divide the dog ear into three portions for the description purpose – the external, middle, and internal ear.
The anatomy of the dog external ear consists of skin-covered cartilages, auricle, and external acoustic meatus. It is a somewhat funnel-shaped structure but may vary between species and within the domestic breed.
The auricle or pinna is the externally visible part of the external ear of a dog. It is roughly an elongated funnel-shaped structure with two surfaces, two borders, a base, and an apex. But the shape of the auricle or pinna of the dog varies with the breed.
In dog ear cartilage anatomy, you will find three types of cartilages – auricular, annular, and scutiform. The auricular cartilage is large and forms the shape of the dog ear. Again, the scutiform cartilage is a small quadrilateral shape that attaches to the cranial aspect of the base of the auricular cartilage.
The external acoustic meatus of the dog ear is the canal that forms the base of the auricle to the tympanic membrane. This canal is bounded by the annular cartilage and the tubular part of the auricular cartilage.
In the dog middle ear anatomy, you will find three important features – the tympanic membrane, tympanic cavity, and auditory ossicles. Here, I will show you the important features from the dog’s middle ear with the labeled diagrams.
Several ligaments attach the ossicle to the wall of the tympanic membrane of the dog ear. Here, I will enlist the ligaments that are found in the dog middle ear anatomy.
If your dog’s eardrum has become perforated, you will need to seek veterinary attention. An eardrum that is perforated and left untreated can cause long-term effects for your dog and even deafness in the affected ear.
You may not be aware that your dog is suffering from an eardrum rupture and just assume that they are ignoring you or being stubborn. There are several symptoms that will let you know that there is something wrong with your dog and you need to make a trip to see your veterinarian. These symptoms include:
An eardrum rupture can result from a number of things. You may never figure out what caused your dog’s eardrum to rupture, but you should never leave a ruptured eardrum untreated. Potential causes include:
Your veterinarian will begin the appointment by taking a medical history of your dog and then performing a physical examination. An ear examination is needed to properly diagnose an eardrum that has ruptured. Many dogs will need to be sedated during the ear examination.
Once your dog has been diagnosed with an eardrum rupture, your veterinarian will discuss your treatment options with you. Be sure to follow your veterinarian’s instructions and give any prescribed medication as directed.
A ruptured eardrum will usually heal within three to six weeks if the rupture has not required surgery and your dog responds well to the treatment plan. Depending on severity of the rupture, your dog may experience permanent hearing loss or even permanent neurological complications.
My dog was on Zicam for a week and was doing great on it. Her ear wad looking much better. This morning she was whining about her ear. There’s almost a clear substance coming from it that’s slightly tinted red/brown. The discharge isn’t nearly as bad as the first few days of the infection.
Earwax Gland Tumors. Benign or malignant tumors of the earwax glands (called ceruminous glands) can develop in the external ear canal.. These tumors can appear as smooth or bumpy stalk-shaped lumps or flattened patches that rise off the lining of the ear canal. A deep biopsy of the tissue is necessary for diagnosis.
Average survival time of animals with malignant ear canal tumors has been reported to be almost 5 years in dogs; however, dogs with extensive tumor involvement had a less favorable outlook. Radiation therapy can be used to treat incompletely removed malignant earwax gland tumors, with a 56% 1-year survival rate reported.
If the middle or inner ear is involved, the dog may have loss of balance and coordination, deafness, head tilt, and other neurologic signs. In any case of inflammation in one ear that does not respond to treatment, a tumor of the ear canal should be suspected by your veterinarian.
Of those that are malignant, less than 10% spread beyond the local area. Signs of ear canal tumors include ear discharge (waxy, pus-filled, or bloody) in one ear, a foul odor, head shaking, ear scratching, and swelling or draining abscesses near the ear. If the middle or inner ear is involved, the dog may have loss of balance and coordination, ...
Tumors may develop from any of the structures lining or supporting the ear canal, including the outer layer of skin, the glands that produce earwax and oil, or any of the bones, connective tissues, muscles, or middle layers of the skin. Tumors of the external ear canal and pinna are more common than tumors of the middle or inner ear.
A deep biopsy of the tissue is necessary for diagnosis. Computed tomography (CT scan) or magnetic resonance imaging (MRI) may also be needed to determine whether the tumor is invading surrounding tissues, including the middle ear.
Earwax gland tumors may be malignant or benign. Surgical removal of benign ear canal tumors is possible in many cases. Laser surgery has also been used. More extensive surgery is required for malignant ear canal tumors. Average survival time of animals with malignant ear canal tumors has been reported to be almost 5 years in dogs; however, ...
Tissue death of the pinna can occur due to blood clots that form within blood vessels. The decreased blood flow to the area causes open sores to form, with scaling, thickening, and darkening of the surrounding skin. Skin changes start at the tip of the pinna and then spread along its inner surface.
The hair coat begins to thin when a dog is less than 1 year old, and complete hair loss on the outer ear may occur by 8 to 9 years of age. Other commonly affected areas are the neck, chest and thighs. There are no other signs. No effective treatment has been reported, but certain drugs may be helpful.
Other parts of the body (face, armpits, groin, and feet) are also often affected. Veterinarians diagnose allergies based on the dog's signs and history and by ruling out other causes. Food allergies are diagnosed or ruled out with a strict diet trial, which must adhere closely to the veterinarian's directions.
Ear hematomas are fluid-filled swellings that develop on the inner surface of the ear flap in dogs. The cause for their development is unknown, but head shaking or ear scratching due to itchiness is usually involved. In dogs, the condition is seen with environmental or food allergies in which the ear canals are the primary sites of allergic inflammation and itching. Treatment usually involves surgery to drain and flush the swellings. Frequently, the veterinarian will place a drain made out of a soft tube in the area to help prevent fluid from building up again. Medications may also be prescribed.
This inflammation, called contact dermatitis, can develop 1–7 days after starting a treatment.
Canine juvenile cellulitis is an infection and inflammation of the tissues beneath the skin of young dogs. It is an uncommon disorder of puppies and is characterized by masses of small, round raised areas of inflamed skin filled with pus on the face and ears.
Allergies. Allergies caused by environmental allergens (such as dust mites, pollens, or molds) or food are common in dogs and frequently cause redness and itchiness of the ears. Allergies often lead to ear canal infections, which can extend to the pinna (outer ear). Other parts of the body (face, armpits, groin, and feet) are also often affected.
Dogs are more prone to ear infections than humans because of the shape of their ear canals. Prevention is key — learn how to clean your dog’s ears safely. If your dog is showing any of the common signs of ear infections, it’s important to visit your veterinarian as soon as possible. Many dog owners have learned to recognize the telltale signs ...
The most common is otitis externa, in which inflammation affects the layer of cells lining the external portion of the ear canal. Otitis media and interna refer to infections of the middle and inner ear canal, respectively. These infections often result from the spread of infection from the external ear. Otitis media and interna can be very serious ...
In severe cases, your vet may prescribe oral antibiotics and anti-inflammatory medications. Most uncomplicated ear infections resolve within 1–2 weeks, once appropriate treatment begins.
Jeff Grognet, DVM, a columnist for AKC Family Dog, advises the following steps for ear cleaning: “First, fill the canal with a dog ear cleaning solution and massage the vertical ear canal from the outside. Wipe out the canal with absorbent gauze.
Factors that may predispose your dog to ear infections include: Moisture, which can create a prime growing environment for bacteria and yeast. Allergies, which lead to ear disease in about 50 percent of dogs with allergic skin disease and 80 percent of dogs with food sensitivities.
In cases of severe chronic disease where other treatments have failed, your veterinarian may recommend surgery such as a Total Ear Canal Ablation (TECA). A TECA surgery removes the ear canal, thus removing the diseased tissue and preventing the recurrence of infection.
Be prepared to provide your vet with a thorough history of the problem. This is especially important for first-time infections, or if you are seeing a new veterinarian. Your vet will want to know the following: Duration of any symptoms, such as pain, swelling, discharge, and odor.
