Understanding Oronasal Fistulas
Oronasal fistulas, although rare, can occur in cats and require attention to ensure the well-being of your feline companion. This section will explore the causes and locations of oronasal fistulas in cats, as well as the symptoms associated with this condition.
Causes and Locations
Oronasal fistulas in cats can be attributed to various factors. One common cause is diseased conditions affecting any tooth in the upper jaw, with the most frequent location being where the root of the fourth premolar on the upper jaw enters the palate (PetMD). Other causes include neoplasia (abnormal tissue growth), trauma, foreign bodies, severe periodontal disease, improper tooth extraction, and damage to the alveolar bone during surgery. In some cases, the loss of bones such as the palatine, maxilla, or incisive bones can result in the formation of an oronasal fistula.
Traumatic oronasal fistulas can occur due to skull trauma that leads to the destruction of the palate, separating the oral and nasal cavities. Causes of traumatic fistulas include chronic infection from periodontal disease, bite wounds, blunt trauma, neoplasia, and electrocution (NCBI).
Symptoms in Cats
Identifying the symptoms of oronasal fistulas in cats is crucial for early detection and intervention. Some common symptoms include:
- Nasal discharge: Cats with oronasal fistulas may exhibit chronic nasal discharge, which can range from clear to bloody.
- Sneezing: Persistent or frequent sneezing is another symptom that may indicate the presence of a fistula.
- Dropping of food while eating: Cats with oronasal fistulas may experience difficulty in keeping food in their mouths while eating, leading to food dropping out.
- Accumulation of blood in the mouth: Blood may accumulate in the mouth due to the fistula, causing discomfort and potential bleeding.
- Increased saliva production: Cats with oronasal fistulas may exhibit increased saliva production, which can be a sign of underlying issues.
If you notice any of these symptoms in your cat, it is essential to consult a veterinarian for a proper diagnosis and appropriate treatment. Early detection and intervention can help prevent complications and promote the well-being of your feline friend.

Diagnosis and Treatment
When it comes to identifying and addressing oronasal fistulas in cats, a proper diagnosis and appropriate treatment are essential. In this section, we will explore the diagnostic procedures used to identify oronasal fistulas and the surgical correction methods employed to treat this condition.
Diagnostic Procedures
Diagnosing an oronasal fistula in cats involves a combination of physical examination, history assessment, and additional diagnostic tests. During a routine dental cleaning, a veterinarian may identify the presence of an oronasal fistula through a physical examination of the cat’s mouth (Wagwalking). A periodontal probe may be used to investigate suspected fistulas, and dental radiography and periodontal probing are essential for diagnosis.
To evaluate the overall health of the cat and ensure it can withstand surgery, pre-surgical lab work, including a biochemistry profile and urinalysis, is typically conducted. This helps provide a comprehensive understanding of the cat’s health status before proceeding with the surgical correction (Wagwalking). A thorough history of the cat’s health, symptoms, and possible incidents related to the condition will also be taken into consideration during the diagnostic process.
Surgical Correction
Surgical correction is the primary treatment option for oronasal fistulas in cats. The surgical procedure involves the removal of the affected tooth and the closure of the passageway. During closure, a skin flap is placed both in the mouth and in the nasal cavity to ensure proper sealing and healing (PetMD).
Following the surgical correction, cats are typically prescribed pain medications and antibiotics to manage discomfort and prevent infection. It is important to follow the veterinarian’s instructions regarding medication dosage and administration. Additionally, a soft food diet is recommended during the recovery period to minimize irritation to the surgical site. Physical activities should be limited to allow for proper healing.
Regular follow-up appointments with the veterinarian are crucial to monitor the healing progress and address any potential complications that may arise. By adhering to the post-surgery care instructions and providing appropriate aftercare, the chances of a successful recovery are significantly enhanced.
Understanding the diagnostic procedures and surgical correction involved in treating oronasal fistulas in cats is essential for cat owners. By seeking proper veterinary care and following the recommended treatment plan, the overall health and quality of life for cats affected by oronasal fistulas can be significantly improved.
Surgical Considerations
When it comes to treating oronasal fistula in cats, surgical correction is the primary option. After the surgery, proper post-operative care is crucial to ensure a successful recovery. Additionally, it’s important to be aware of potential complications and the possibility of revisions.
Post-Surgery Care
Following the surgical procedure, cats with oronasal fistulas require attentive post-surgery care. The veterinarian will typically prescribe pain medications and antibiotics to manage any discomfort and prevent infection. It is essential to administer these medications as directed by the veterinarian.
To aid in the healing process, cats may be placed on a soft food diet to minimize stress on the surgical site. The soft consistency of the food reduces the risk of irritation and helps prevent any disruption to the healing tissue. It’s important to follow the veterinarian’s dietary recommendations during the recovery period.
During the post-surgery period, it is advisable to limit the cat’s physical activities to prevent any strain or damage to the surgical site. Providing a calm and quiet environment can help reduce stress and promote healing. It’s essential to monitor the cat closely for any signs of discomfort, infection, or complications and promptly consult the veterinarian if any concerns arise.
Complications and Revisions
Oronasal fistulas in cats may occasionally reopen due to constant tension caused by breathing. In such cases, additional surgeries with advanced tissue flaps may be necessary to address the issue. These revisions aim to improve the closure and reduce the risk of recurrence.
One potential complication is dehiscence, which refers to the separation of the surgical incision or wound. Tension on the flap during the surgery should be avoided, as it can lead to dehiscence. Surgeons emphasize the importance of maintaining no tension on the flap to minimize the risk of complications (dvm360).
In some cases, the repair of oronasal fistulas may require multiple surgeries. For instance, a cat may undergo a second surgery involving the extraction of remaining teeth to increase the size of buccal flaps. However, despite initial success, graft failure can occur due to inadequate blood supply and trauma from eating dry cat food.
Regular follow-up appointments with the veterinarian are essential after the surgery to monitor the healing progress and address any concerns. By closely adhering to post-surgery care instructions and promptly seeking veterinary assistance if complications arise, the chances of a successful recovery from oronasal fistula surgery can be significantly improved.
Preventing Oronasal Fistulas
Taking preventive measures against oronasal fistulas in cats is essential to maintain their oral and overall health. There are two key aspects to focus on: dental hygiene and early detection with proper maintenance.
Dental Hygiene
Good oral hygiene plays a vital role in preventing oronasal fistulas in cats. Regularly brushing your cat’s teeth using a pet-specific toothbrush and toothpaste is highly recommended. This helps remove plaque and tartar buildup, reducing the risk of dental disease and subsequent complications. Providing dental chews or treats designed to promote oral health can also contribute to maintaining a healthy mouth.
Scheduling routine dental exams and cleanings with a veterinarian is crucial. These appointments allow for a thorough evaluation of your cat’s dental health, identification of any potential issues, and professional cleaning to remove stubborn plaque and tartar. Regular veterinary care ensures that any dental problems are addressed early on, reducing the risk of complications that may lead to oronasal fistulas.

Early Detection and Maintenance
Early detection of dental issues is key to preventing oronasal fistulas in cats. It is important to be aware of the signs and symptoms of dental disease, such as bad breath, difficulty eating, drooling, pawing at the mouth, and inflamed gums. If you notice any of these signs, consult a veterinarian promptly for a thorough examination.
One of the most common locations for oronasal fistulas in cats is where the root of the fourth premolar on the upper jaw enters the palate. Regular dental check-ups can help identify any diseased conditions or abnormalities in this area. If an oronasal fistula is detected, surgical correction is necessary to prevent food and water from passing from the mouth into the nasal cavity, which can lead to various complications such as irritation of the nose, runny nose, sinus inflammation, infection, and even pneumonia.
Maintaining proper oral health after surgical correction is crucial. Your veterinarian will provide guidance on post-surgery care, including any necessary medications or dietary adjustments. Regular follow-up visits will also be recommended to monitor your cat’s progress and address any concerns that may arise. By adhering to these recommendations, you can reduce the risk of complications and help your cat recover successfully.
By focusing on dental hygiene and early detection with proper maintenance, you can significantly reduce the likelihood of oronasal fistulas in your cat. Regular dental care, along with prompt veterinary attention, ensures a healthy oral environment and overall well-being for your feline companion.
