Today we are looking at Canine Oronasal Fistula Repair and finding out a bit more about Oronasal Fistulas too!

Facts About Canine Oronasal Fistulas

A fistula is, by definition, a communication path that connects two separate locations. Consider a fistula to be similar to a hole in a wall that allows you to look through the wall into the next room when it is closed.

In the oral cavity and nasal route, oronasal fistulas are aberrant connections, or holes, that exist between the two structures.

In the normal architecture of the upper jaw (maxilla), the nasal passageways are divided from the oral cavity by soft tissue and bone, as seen in the illustration below (like a wall).

It is possible to develop a communication channel between the oral cavity and nasal airways when these tissues are injured, much like a hole in a wall between the two.

It is possible for food, drink, and saliva to flow from the mouth to the nose in pets that have developed an oronasal fistula. This can irritate the respiratory system and cause the pet pain and suffering.

Chronic infection might develop, and the pet may become unable to eat or drink as a result of the pain that is connected with it. Pets with oronasal fistulas may exhibit the following symptoms:

  • Excessive sneezing and sniffling
  • Expulsion of mucus from the nose
  • Sneezing food out of your nose
  • Inflammation and persistent infections of the respiratory tract are two conditions that might occur.

The Causes Of

Dental disease is the most prevalent cause of oronasal fistulas in pets, accounting for about half of all cases.

Periodontal disease is the most common reason for oronasal fistulas to develop. Periodontal disease is an infection of the supporting tissues that surround the teeth and is caused by bacteria. These tissues include the gingiva, periodontal ligament, cementum, and bone, all of which work together to hold the teeth in their proper positions.

Eventually, when the periodontal disease worsens, these tissues will be worn away and destroyed.

A fistula is formed between the oral cavity and the nasal airways when the periodontal tissues become weaker or entirely destroyed as a result of extensive erosion. In the upper canine (fang) teeth, the most typical location for an oronasal fistula is at their gum line.

They can, however, form around other teeth as well as around the front teeth.

Some of the other most common causes of oronasal fistulas are trauma to the maxillofacial (upper jaw) area (such as being hit by a car or being bitten by another dog) and aggressive oral malignancies.

They can also occur during a tooth extraction. Around some tooth roots, the bone that separates the tooth root from the nasal canal is thin.

The bone can shatter if overly aggressive extraction procedures are used, or if the bone is already fragile as a result of periodontal disease. This results in an oronasal fistula being formed.

By the age of three, the majority of pets have developed some degree of periodontal disease.

Severe dental disease, the most prevalent cause of oronasal fistulas, causes the bone surrounding a pet’s teeth to become weak, resulting in gaps forming between the mouth and the respiratory tract.
These spaces are ideal breeding grounds for germs to accumulate and infection to spread, necessitating the excision of the afflicted tooth or teeth in most cases.
An oronasal fistula can occur after extraction if so much bone has been removed that the tube between the mouth and the nasal passages is exposed.

Oronasal fistulas can be caused by a variety of factors, including trauma, malignancy, and a cleft palate.

The Symptoms To Look For

It is possible to observe the oronasal fistula during an awake oral exam if the fistula is large enough. The absence of an anesthetic can make it difficult to diagnose oronasal fistulas unless the patient undergoes a comprehensive examination under anesthesia.

When rhinitis-related symptoms such as nasal discharge and sneezing are present, the majority of oronasal fistulas are suspected. They are also more common in people who have advanced dental disease.

Treatment Of Canine Oronasal Fistulas

Canine Oronasal Fistula Repair

An oronasal fistula is a type of fistula that requires surgical correction.

The sooner an oronasal fistula is treated, the better the prognosis, because chronic fistulas are difficult to repair and frequently do not heal completely on their own after they have developed.

An oronasal fistula can only be repaired through surgery performed under general anesthesia.

After determining the depth of the fistula and removing any debris or bacteria from the area, we look for healthy gum tissue to sew over the fistula to close it, which might be difficult if the pet’s mouth is seriously ill.

After surgery, the pet should be restrained from chewing on anything hard, including dry food, for two to three weeks following the procedure.

Living & Management Of The Condition

The most effective method of preventing oronasal fistulas in pets is through good oral hygiene.

Good dental hygiene is essential for preventing bone loss and infection, both of which can impair periodontal support systems and result in oronasal fistulas in the mouth.

Brushing your pet’s teeth on a regular basis, providing dental chews, and scheduling routine dental checkups and expert cleanings are all important steps in maintaining your pet’s oral health in good health.

Canine Oronasal Fistula Repair is something that you may well have to consider during the lifetime of your dog but this can be rarer as a condition if you look after your dogs teeth.

As previously said, your pet’s oral health is extremely vital. If you notice any problems with your pet’s dental treatment, please get in touch with your vet as soon as possible.
