Ricky, (his name may have been changed to protect his true identity) a male Shar pei from Maryland was seen at our hospital in Chester, PA with a severe long term ear infection in both ears. The ear canals, which are “L” shaped, do not allow air to dry the canals nor allow fluid to escape once the canals begin to close down due to infection.

Ricky had severe discomfort, smelly ears, and was very
afraid of even being touched. He could only be examined with a little sedation.
The medical term for Ricky’s condition is called Otitis externa or an inflammation of the ear canal.
This occurs when the lining of the
ear becomes inflamed and thickened, thereby blocking air and fluid flow in and out
of the canal. Animals with otitis externa can also develop otitis media (middle
ear inflammation).
In puppies and kittens, otitis externa is often caused by ear mites. These tiny parasites cause terrible itching and a thick brown discharge. In adult dogs, the most common underlying cause is allergies- sensitivity to something in the environment or to food. In older animals, tumors can cause blockage of the ear canal and secondary infection. Other predisposing causes may include foreign bodies (such as grass seeds), or small ear canals (often seen in Shar Pei) or long floppy ear flaps (for example, Basset hounds) that prevent air flow.
Dogs with otitis externa may
start out with mild signs, but symptoms can progress with time or from failed treatment
attempts, such as:
- · scratching their ears or shaking their heads
- · ears may be thick or red on the underside or hairless part
- · ears may have a strong, unpleasant smell
- · ear canal will eventually be blocked and have a cauliflower-like appearance
- · white thick discharge from the ears of dogs if bacterial infections are present
Because the condition is painful, particularly when the middle ear
is affected, pets may have personality and behavioral changes. They may shy
away from being petted on the head, and may be uncomfortable opening their
mouth wide or chewing food. Additionally, blockage of the ear canal
muffles their hearing and makes them less responsive to their
owners.
In Ricky’s case, we obtained
samples of the discharge, did a culture & sensitivity and decided what
antibiotics to put him on. Additionally, we added multiple Cold Laser Therapy
sessions to make Ricky more comfortable and possibly open the ear canals prior
to the planned surgery.
Medical management is sufficient and preferred
in pets that have inflammation and discharge of the ear canals, but no
blockage. The ear canals are cleaned and flushed, and your veterinarian may
even need to drain the middle ear to relieve the fluid buildup. Pets are
treated with a medication that kills mites, bacteria, or yeast, depending on
what type of organism is found in the canal. In Ricky's case, just medical treatment was not enough. He needed a Lateral Ear Resection. Picture a cylinder pipe with only one end open. Now picture the pipe full of moisture and dirt. The only way to dry the pipe out and have access to the inside of the pipe is if you cut the pipe open length-wise. Now air can dry the pipe and you can get a cloth onto the entire pipe to clean it out. This is what we did for Ricky's ear canals.
· Lateral Ear Canal Resection
(“Zepp”) Procedure
Opening the lateral and vertical part of the ear canal opens it up to air and the owners accessibility in cleaning the canal.
Ricky had his Zepp procedure
today and did very well. Just the vertical canal was opened. In a few months, we will assess Ricky's actual progress.
Owners of certain breeds of
dogs, such as Cocker spaniels, Shar Pei, and Bassett
hounds should be prepared for ear problems. These
dogs should have their ears checked once or twice a year, and any ear
infections should be treated promptly to prevent inflammation and thickening of
the canal. Any dogs prone to skin or food allergies should also be checked
annually.
